IMPORTANT!

MultiRAE-series instruments use instrument firmware version 1.50/sensor firmware version 1.50.

IMPORTANT! BUMP TEST THE MONITOR BEFORE EACH DAY’S USE

Prior to each day’s use, every gas detection monitor should be bump tested to confirm the response of all

sensors and activation of all alarms by exposing the monitor to a concentration of target gas that exceeds the low alarm set point. A bump test is also recommended if the monitor has been subjected to physical

impact, liquid immersion, an Over Limit alarm event, or custody changes, or anytime the monitor’s

performance is in doubt.

To ensure greatest accuracy and safety, only bump test and calibrate in a fresh air environment.

The monitor should be calibrated every time it does not pass a bump test, but no less frequently than every six months, depending on use and exposure to gas and contamination, and its operational mode.

• Calibration intervals and bump test procedures may vary due to national legislation.

• Honeywell recommends using calibration gas cylinders containing the gas that is appropriate to the

sensor you are using, and in the correct concentration.

3 General Information

The MultiRAE is a family of multi-threat gas detectors that combine continuous monitoring capabilities for volatile organic compounds (VOCs), toxic and combustible gases, and radiation, with Man Down Alarm functionality in one highly portable instrument. MultiRAE monitors offer an industry-leading selection of interchangeable field-replaceable electrochemical, combustible, infrared, PID (photoionization detector), and gamma radiation sensors to fit a wide variety of applications. The MultiRAE family’s wireless capability elevates worker protection to the next level by providing safety officers real-time access to instrument readings and alarm status from any location for better visibility and faster response.

Notes:

 NDIR combustible sensors are not supported on the diffusion version with CSA certification.  The PID sensor requires a pumped configuration.  If a %Vol. NDIR sensor is installed in an instrument, a catalytic bead %LEL sensor must also be

installed in the instrument for CSA certification.

 MultiRAE Benzene is designed specifically for use with the benzene-specific cartridge.

IMPORTANT!

The benzene-specific cartridge cannot be used on other MultiRAE models.

3.1 Key Features

 All-in-one continuous monitoring capabilities for gamma radiation, VOCs, oxygen, toxic

and combustible gases, for a total of up to six threats at a time

 Highly customizable with over 25 field-interchangeable intelligent sensor options  Wireless access to real-time instrument readings and alarm status from any location

through ProRAE Guardian Real-Time Wireless Safety System

 Unmistakable five-way local and remote wireless notification of alarm conditions,

including Man Down Alarm

 Large graphical display with easy-to-use, icon-driven user interface  Simple maintenance with easily accessible sensors, pump, and plug-and-play battery  Fully automated charging, data management, bump testing and calibration with AutoRAE 2

4.1.2 Keys And Interface

The MultiRAE has three keys:

Y/+

MODE

N/-

In addition to their labeled functions, [Y/+], [MODE], and [N/-] act as “soft keys” that control different parameters and make different selections within the instrument’s menus. From menu to menu, each key

controls a different parameter or makes a different selection.

Three panes along the bottom of the display are “mapped” to the keys. These change as menus change,

but at all times the left pane corresponds to the [Y/+] key, the center pane corresponds to the [MODE] key, and the right pane corresponds to the [N/-] key. Here are examples that show the relationships of the keys and functions:

In addition to the functions described above, any of the keys can be used to manually activate display backlighting. Press any key when the backlighting is off to turn it on. A subsequent key press is required to carry out an actual function corresponding to that key.

4.1.3 LCD Flip

The MultiRAE senses its vertical/horizontal orientation, and can automatically flip the display 180 degrees, making it easy to read if the MultiRAE is upside down. (You can turn this feature on or off in Programming Mode, under “Monitor/LCD Flip.”)

As the MultiRAE is tilted, the gravity sensor detects its orientation and inverts the screen when it is past its horizontal position.

4.1.4 Key Remapping When LCD Is Flipped

When the instrument is inverted and the LCD flips, the keys are remapped to the functions shown on the screen.

4.2 Screen Display For Various Numbers Of Active Sensors

The MultiRAE family of instruments can display readings from one to six sensors (including dual sensors), depending on the configuration. In order to maximize readability and the amount of information shown, the display is automatically reconfigured, according to the number and types of sensors in the MultiRAE.

If the configuration includes five sensors, and one of them is a PID, then the lamp value is shown, along with the currently applied correction factor (CF) and measurement gas.

One sensor.

Two sensors.

Three sensors.

Four sensors.

Five sensors, including Gamma radiation sensor.

Five sensors, including PID, showing lamp type, correction factor, and measurement gas.

Six-sensor configuration with CO+H2S combo sensor.

When used in TVOC mode, MultiRAE Benzene shows all sensor readings continuously

In benzene mode, the display prompts for snapshot sampling.

Toggle Display is standard on MultiRAE Benzene to alternate between LEL and VOC reading and their CFs. ProRAE Studio II allows other MultiRAE instruments to toggle the display for PID and LEL readings and CFs.

4.3 Menus

The reading menus are easy to step through by pressing the [N/-] key.

Hygiene Mode: Sampling is continuous, and Hygiene Mode allows you to clear peak and minimum values at any time.

Search Mode: Samples only when you tell it to sample. This allows you to save sample readings as individual events in the datalog. You can also clear peak and minimum values.

Notes:

 You can switch between Hygiene and Search modes via the Programming Menu (Select Monitor

and then Operation Mode).

 If the instrument is not equipped with a VOC sensor (PID), or is not equipped with an LEL

sensor, then screens for those sensors (VOC Gas Status and LEL Gas Status, respectively) are not shown.

 Operation of Wi-Fi-equipped MultiRAE Lite is shown on page 19.  Search Mode is not available on MultiRAE Benzene.  MultiRAE Benzene operation is shown on page 22.

4.3.1 Hygiene Mode

Note: Dashed line indicates automatic progression.

4.3.2 Search Mode

Notes:

 If the instrument is not equipped with a VOC sensor (PID), or is not equipped with an LEL

sensor, then screens for those sensors (VOC Gas Status and LEL Gas Status, respectively) are not shown.

 If the Peak or Min is cleared, the Average is also cleared. In addition, each cycle through the

main screen after they are cleared will route from “Ready… Start sampling?” directly to Date and Time if you press [N/-] (see red line in diagram below), until you perform a new sample. Also, if you start sampling again and stop sampling, clear the Peak, or clear the Min, it advances to Date and Time, as well.

Note: Dashed line indicates automatic progression.

MultiRAE Benzene (TVOC and Benzene Modes)

Notes:

 When prompted to start benzene sampling, there is an option to view a tutorial. This is helpful if

you do not have this User’s Guide in the field or if you are unfamiliar with how to ready the

MultiRAE Benzene for benzene sampling. If the option is not shown, follow the procedure on page 41.

 Benzene sampling is done in a “snapshot,” meaning that the instrument does not continuously

monitor for benzene.

Note: Dashed line indicates automatic progression.

5 Wireless Control And Submenus

When you step through the main menu, as shown in the previous diagrams, there are screens for wireless communication.

Note: These are only present if the MultiRAE is equipped with a wireless module. At the Radio On/Off screen, you can turn the radio on or off, if the MultiRAE is in Advanced User

Mode. The radio turns off instantly, but turning on the radio takes a few seconds, so you see a screen that indicates the radio is being turned on. If the instrument is in Basic User Mode, the option for turning the radio on or off does not appear (you can turn it on or off in Programming Mode).

All wirelessly equipped models, except those with Wi-Fi, also have the following screens. At the Wireless screen, you can check communication with other wireless devices and get other useful information about the wireless settings. The Wireless menu is divided into a sequence of four “pages,” each presenting different information. As you press [Y/+] on each of the “pages,” you advance to the next one.

Unit ID (unique identifier of the instrument’s radio), Pan ID, and Channel are read-only parameters that help you to check whether the instrument’s wireless settings are correct (very helpful for troubleshooting).

The next “page,” Parent ID and Device Type are also read-only. The Parent ID (the ID of the “Parent” wireless device to which the monitor is connected) is not changeable. The device type tells you that it is “Standard,” meaning it transmits and receives.

The third “page” is labeled “Ping,” where you can check the signal strength via RSSI (received signal strength indication) and “ping” the network to confirm an active two-way communication

network. Each time you press [MODE] to “ping” the network, a number of sends is included under “Sent.” If the network receives the signal and sends one back, which is in turn received by

the MultiRAE, then a number is added under “Received.” The fourth “page” includes the type of transmitter (Region), Radio Type (model), and Tx Power

(transmission power). These are primarily for diagnostics and troubleshooting.

When you reach the fourth “page,” you can wrap around to the first one by pressing [Y/+].

Otherwise, you can press [N/-] to quit, which advances to the next screen.

6 Point-To-Point Wired Connection

The MultiRAE can communicate with other devices through P2P (point-to-point) wiring. Turning on P2P requires connecting the MultiRAE with a computer running ProRAE Studio II software and toggling P2P on. Note: When P2P is active, the wireless modem (if one is installed in the MultiRAE) is disabled.

Refer to page 102 for detailed information on connecting the MultiRAE to a PC running ProRAE Studio II.

6.1 Using ProRAE Studio II To Set P2P Operation

6.2 Connecting A MultiRAE To A PC To Enable Point-To-Point Operation

Once the MultiRAE is configured for P2P (point-to-point) communication, you must connect it to a PC or other equipment that it will communicate with.Connect the MultiRAE to the computer

using the special RS232 Travel Charger and its mini-USB to DB9 cable (the standard MultiRAE Travel Charger and mini-USB-to-USB PC communications cable will not support P2P). If your computer does not have a DB9/RS232 serial port, use the USB-to-Serial Adapter (P/N: 410-0210-000) to connect the mini-USB to DB9 cable to a PC’s USB port.

Supply power to the RS232 Travel Charger. Either attach the AC adapter to the RS232 Travel Charger, or plug its USB-A plug into an active USB port on the computer for power. The RS232 Travel Charger will not operate without a power source.

Note: Do not plug in both the USB and the AC adapter at the same time, as this may cause errors. Follow one of the three diagrams below for power and data connection options.

Note: Refer To RAE Systems Technical Note TN-190 for more information on how point-to-point operation works.

7. Battery

Always make sure the batteries are fully charged before using the MultiRAE. Three battery options are available for the MultiRAE (PGM 62x6/62x8):

1. Standard duration rechargeable Li-ion battery (PN: M01-3051-000)

2. Extended-duration rechargeable Li-ion battery delivering 50% more runtime than the standard

battery (PN: M01-3056-000)

3. Alkaline battery pack for four standard AA-sized batteries (PN: M01-3052-000)

Its standard or extended-duration batteries are charged inside the instrument by placing the MultiRAE in its cradle or using the Travel Charger. Contacts on the bottom of the instrument meet the cradle’s contact pins, transferring power.

Note: Before setting the MultiRAE into its MultiRAE Desktop Cradle or attaching its Travel Charger, visually inspect the contacts to make sure they are clean. If they are not, wipe them with a soft, dry cloth. Do not use solvents or cleaners.

WARNING

To reduce the risk of ignition of hazardous atmospheres, recharge, remove or replace the battery only in an area known to be non-hazardous! Do not mix old and new batteries or batteries from different manufacturers.

6.3 Charging With The MultiRAE Desktop Cradle

Follow this procedure to charge the MultiRAE:

1. Plug the AC/DC adapter into the MultiRAE’s Desktop Cradle.

2. Plug the AC/DC adapter into the wall outlet.

3. Place the MultiRAE into the cradle (make sure the bottom of the instrument and the alignment pins on the cradle mate properly) and press down until it is locked in place.

The MultiRAE begins charging automatically. The LED in the cradle should glow red to indicate charging. When charging is complete, the LED in the cradle glows green.

To remove the MultiRAE from the Desktop Cradle, tilt it toward you until it releases, and then lift it up.

Next, put the plug from the power supply into the jack on the side of the Desktop Cradle:

Press down until MultiRAE is seated firmly in the cradle

Release the MultiRAE by tilting it forward and lifting

Plug the other end of the charger into a power source.

6.4 Automatic PID Cleaning

MultiRAE products offer auto-cleaning, a unique feature that reduces PID lamp cleaning. When a MultiRAE equipped with a PID lamp is charging in a desktop cradle, truck mount, or AutoRAE 2 cradle (but not a Travel Charger), the PID lamp turns on for two hours and generates a small concentration of ozone. Ultraviolet light and ozone molecules then burn off heavy contaminants that may have built up on the lamp and sensor. Then the pump runs for 20 minutes to exhaust gas contained inside the gas plate. After the pump stops, the battery continues to be charged, if necessary. Note: This function also works when the instrument is turned off

6.5 Charging With The Travel Charger

The Travel Charger is a lightweight portable alternative to the Desktop Cradle for charging and PC communications. Follow these steps to use the Travel Charger.

Before attaching the Travel Charger, check that it is aligned correctly with the base of the MultiRAE. There are two alignment pins on one side and one alignment pin on the other side, designed to mate with matching points on the bottom of the MultiRAE:

1. Check bottom of MultiRAE

Travel Charger’s alignment pins

for correct orientation with the MultiRAE.

2. Align Travel Charger with bottom of MultiRAE.

3. Press Travel Charger onto bottom of MultiRAE.

4. Make sure the Travel Charger clicks into place and attaches firmly.

Next, put the plug from the power supply into the jack on the side of the Travel Charger:

Plug the other end of the charger into a power source (AC outlet or 12VDC mobile power port, depending on the model). When power is applied and the MultiRAE’s battery is charging, the LED glows red. The LED glows green when the battery is fully charged.

6.6 Carrying The MultiRAE In A Vehicle

If you try to charge alkaline batteries installed in the instrument, the Charging Cradle or Travel Charger’s charging LED does not glow, indicating that it will not charge them.

The alkaline battery adapter accepts four AA alkaline batteries (use only Duracell MN1500). Do not mix old and new batteries or batteries from different manufacturers.

Note: When replacing alkaline batteries, properly dispose of old ones.

7 Turning The MultiRAE On And Off

7.1 Turning The MultiRAE On

With the instrument turned off, press and hold the [MODE] key until the beep sounds and the display and LED alarm lights turn on, and then release.

A RAE Systems logo (or a company name) should appear first. This is followed by a progression of screens that tell you the MultiRAE’s current settings:

 Product name and model number, air flow type, and serial number  Application firmware version, build date, and build time  Sensor firmware, build date, build time  Installed sensors (including serial number/production/expiration/calibration date and alarm limit

settings)

 Current date, time, temperature, and relative humidity  User mode and operation mode  Battery type, voltage, shutoff voltage  Alarm mode and alarm settings  Datalog period (if it is activated) and interval  Policy Enforcement settings (whether calibration and/or bump testing are enforced)

Note: To speed up the startup time, the number of screens shown on startup can be reduced by enabling the Fast Startup option under Programming/Monitor.

Then the MultiRAE’s main reading screen appears. It may take a few minutes for sensors to show a reading, so if any have not warmed up by the time the main screen is shown, you will see “- - -” instead of a numerical value until the sensor provides data (typically less than 2 minutes). Then it displays instantaneous readings similar to the following screen (depending on the sensors installed) and is ready for use.

Note: If the battery is completely empty, then the display briefly shows the message “Battery Fully Discharged,” and the MultiRAE shuts off. You should charge the battery or replace it with a fully charged

battery before turning it on again.

7.2 Turning The MultiRAE Off

Press and hold [MODE]. A 5-second countdown to shutoff begins. You must hold your finger on the key for the entire shutoff process until the MultiRAE is powered off.

7.3 Testing Alarm Indicators

IMPORTANT!

During operation, make sure the probe inlet and the gas outlet are free of obstructions. Obstructions can cause premature wear on the pump, false readings, or pump stalling. During normal operation, the pump icon alternately shows inflow and outflow as shown here:

If there is a pump failure or obstruction that disrupts the pump, the alarm sounds and you see this icon blinking on and off:

Once the obstruction is removed, you can try to restart the pump by pressing the [Y/+]. If the pump does not restart, and the pump stall alarm continues, consult the Troubleshooting section of this guide or contact RAE Systems Technical Support.

It is advisable to perform a pump stall test periodically, to make sure the pump is working properly and there are no leaks in the system. To perform a pump stall test, simply block the gas inlet with your finger. To pass the test, the instrument should go into a pump alarm. Press [Y/+] to disable the alarm and return to normal operation.

Note: Pump Status is not indicated on diffusion MultiRAEs.

Note: For all MultiRAE instruments with a PID (in Search or Hygiene mode), if the pump is in alarm for

more than five minutes, the PID lamp automatically turns off. The display reading shows “- - -” and there is a “Lamp” alarm. Click [Y/+] to restart the pump. If there is no longer a pump alarm, then the PID lamp

will require a 2-minute warm-up to stabilize. During this time, the PID’s reading shows “- - -”. Once the PID lamp is warmed up, the display shows the actual value.

7.6 Calibration Status

The instrument displays this icon next to the sensor that requires calibration:

Calibration is required (and indicated by this icon) if:

 The lamp type has been changed.  The sensor module has been replaced with one whose calibration is overdue.  The defined period of time between calibrations has been exceeded.  If you have changed the calibration gas type without recalibrating the instrument.  The sensor has failed a previous calibration.

8 Modes Of Operation

The MultiRAE has two operation modes and two user modes.

8.1 Hygiene Operation Mode

Hygiene Mode provides continuous monitoring.

8.2 Search Operation Mode

Search Mode provides monitoring only when monitoring is initiated. This allows specific samples to be taken at different times, rather than continuously.

8.3 Benzene-Specific Mode (MultiRAE Benzene Only)

The MultiRAE Benzene can perform snapshot compound-specific (benzene) measurement in addition to general VOC measurement. This requires using a RAE-Sep Tube Cartridge (P/N: M01-3222-000, available in packs of 6: P/N M01-0312-000) and having the MultiRAE Benzene in Benzene Mode.

WARNING!

The RAE-SEP Tube Cartridge is designed to provide six one-time specific measurements of benzene. This cartridge has unique properties and performance features not found in other monitors. It has been designed to provide accurate, benzene-only measurement and has only been evaluated and tested on the MultiRAE Benzene monitor.

Failure to use the MultiRAE Benzene monitor with the RAE-Sep Tube Cartridge will result in inaccurate detection or measurement, which may include the failure to detect benzene and possible serious injury or death.

IMPORTANT!

The RAE-Sep Tube Cartridge is warranted by RAE Systems by Honeywell only for use with the MultiRAE Benzene monitor. Any other use will void the product warranty. In addition, RAE Systems by Honeywell specifically disclaims liability for all loss or damage arising out of any use of the RAE-Sep Tube Cartridge that violates the warnings and instructions in this manual.

8.3.1 Separation Tube Cartridge Installation

Before using the MultiRAE Benzene for benzene-specific measurement, you must attach a RAE-Sep Tube Cartridge to the MultiRAE Benzene. Follow this procedure:

1. Remove the dust filter from the MultiRAE Benzene (if one is currently attached).

2. Align a new RAE-Sep Tube Cartridge with the MultiRAE Benzene’s inlet.

3. Screw on the RAE-Sep Tube Cartridge until it is seated snugly in place.

4. The “B” switch of the RAE-Sep Tube Cartridge should be aligned with the triangle on the inlet.

IMPORTANT!

Do not overtighten any portion of the sampling assembly.

Note: When the MultiRAE Benzene is used only for VOC monitoring, there is no need to use a RAE-Sep Tube Cartridge. Make sure the cartridge is set for TVOC operation (the letter “T” should be visible).

Always rotate the RAE-Sep Tube Cartridge clockwise. Turning it counterclockwise loosens it from the inlet. Rotate the cartridge so that a new (unused) tube is aligned with the “B” marker.

Note the yellow tabs at both ends of each tube. These are for breaking the ends of the tubes to open them.

IMPORTANT!

Break the ends of only one tube at a time.

Press the tab hard to break off the end of the tube to be used. (The broken glass is held inside the cartridge.)

Press the tab at the other end to break open the other end of the tube.

IMPORTANT!

Once a tube’s ends are broken off, the material inside is exposed. Therefore, use the tube for sampling as soon as possible.

Before performing a benzene measurement, check that the tab labeled “B” is pulled all the way out.

Before starting another benzene sample session, turn the RAE-Sep Tube cartridge to the next unused tube.

IMPORTANT!

If the MultiRAE Benzene goes into pump stall (the pump stops, the LEDs flash, and the “Pump Stall” icon appears in the display), check the alignment of the tube and the RAE-Sep Tube

Cartridge setting. Also check that the both ends of the tube have been cracked off. If one has not been cracked off, the sample will not be able to pass through, causing the pump to stall.

Note: After all six RAE-Sep Tubes in the cartridge have been used, remove the cartridge and dispose of it in a safe manner.

8.3.2 Measurement

To perform a benzene-specific measurement, follow this order:

1. Attach the RAE-Sep Tube Cartridge to the MultiRAE Benzene. Make sure it is set for

TVOC measurement (the “T” is showing).

2. Turn on the instrument. Allow it to go through its startup until the main reading screen is

shown.

3. Press [N/-] to advance to this screen:

Note: If the MultiRAE Benzene is in this mode for more than five minutes, it automatically returns to TVOC Mode.

4. Press [Y/+]. You see this screen:

Make sure the cartridge is installed tightly, and the selector shows “B”:

5. Press [Y/+]. You now see this prompt:

Check that the ends of the selected tube are broken.

6. Press [Y/+]. Measurement starts and the instrument shows a countdown (time of

measurement is automatically adjusted to gas sample temperature). Countdown time is automatically adjusted, depending on temperature.

Once the countdown is completed, the display shows a benzene-specific snapshot result (and triggers an alarm if appropriate).

7. Press [N/-] to exit. You see this screen again:

If you want to perform another snapshot benzene-specific measurement, press [Y/+] and continue, using the same procedure as outlined above. Otherwise, press [N/-] to abort. You see this screen:

8. If you are done performing benzene measurements or if you want to use the MultiRAE Benzene

for TVOC operation, either remove the RAE-Sep Tube Cartridge or press the button so that the “B” is hidden and the “T” side is fully exposed (all the way out):

9. Press [N/-] to advance to the main reading screen.

IMPORTANT!

Do not overtighten any portion of the sampling assembly.

Note: When the MultiRAE Benzene is used only for TVOC (total VOC) monitoring, there is no need to use a RAE-Sep Tube Cartridge. If the cartridge is left on during VOC monitoring, make sure it is set for TVOC measurement (the “T” is showing).

8.4 Basic User Mode

In Basic User Mode, some restrictions are applied, including password protection that guards against entering Programming Mode by unauthorized personnel.

** Pump-equipped version only. *** This menu item is shown only if a 3-point calibration is enabled. Change Span2 Value menu item is only

shown if a 3-point calibration is enabled on the instrument. Three-point calibration is disabled by default, but can be enabled on MultiRAE and MultiRAE Pro instruments with 10.6eV PID sensors, including high-range ppm and ppb PID sensors. The MultiRAE Lite PID sensors only support 2-point calibration.

9.3.1 Editing And Selecting Parameters And Sensors

There are a few basic ways to edit parameters, select sensors, and perform other activities in the MultiRAE. The actions performed by pressing keys always match 1-to-1 with the boxes along the bottom of the display and the three keys. Some parameters are edited by scrolling and selecting individual items (black bars behind white text act as highlighters). Some include a choice via “radio buttons,” where only one item in a list can be selected, while other menus use

boxes for you to “check” with an “X,” and these allow for multiple items in a list to be selected.

In all cases of editing, you can save or undo your choice.

9.3.2 Calibration

Use this menu to perform a bump test or zero or span calibration for one or more sensors, and change the gas concentration value used in bump tests and span calibration, as well as choose which sensors will be calibrated at the same time.

9.3.3 Bias & Equilibration For Liquid O2 And Other Biased Sensors

Some electrochemical sensors (NO, NH3, Liquid O2) require a bias voltage to detect the gas, while most do not. Unbiased sensors may be shipped with a shorting pin across the electrodes to avoid an accidental bias. The pin should be removed before installation. Biased sensors require an equilibration time (also known as warm-up time) of at least 6 hours, and sometimes more, after installation for the baseline to become stable enough to calibrate the sensor. Unbiased sensors require at least 10 minutes to stabilize. Once installed, any sensor bias stays on, even when the meter is off. Therefore, even biased sensors are ready for immediate use when the instrument is turned on again, and the equilibration time is needed only when first installed or if the battery becomes completely drained. The SensorRAE 4R+ can be used to maintain bias on NO and other biased sensors, so long equilibration times can be avoided when installing such sensors into a multi-gas instrument.

CAUTION

If an instrument is calibrated directly after sensor installation (no equilibration time, no use of

SensorRAE 4R+), readings will be seen to decrease until the sensor’s bias is is stable. Also, this

may may trigger a low alarm, even if calibration passes.

Refer to RAE Systems Technical Note TN-114 for a list of biased sensors.

9.3.3.1 Fresh Air

This procedure determines the zero point of the sensor calibration curve for all the sensors that require a zero calibration. For the oxygen sensor, Fresh Air calibration sets the point equal to the concentration of oxygen in ambient air (approximately 20.9% volume).

Note: Fresh air calibration is performed on all enabled gas sensors at the same time. To perform Fresh Air calibration on multiple sensors:

1. If using dry air, install the calibration adapter and connect it to a source of dry air. Otherwise do not

use calibration adapter to perform fresh air calibration.

2. At the Calibration Menu, select “Fresh Air.” Press [Y/+] once to enter the fresh air calibration sub-

menu.

3. Start the flow of dry air, if used.

4. Press [Y/+] to start fresh air calibration.

5. A countdown screen appears. You can abort the calibration at any time during the countdown by

pressing [N/-].

6. If the calibration is not aborted, the display shows the sensor names and tells you whether the fresh air

calibration passed or failed, followed by the sensors’ fresh air readings.

Note: Dotted line indicates automatic progression.

9.3.3.2 Multi Sensor Span

Depending on the configuration of your MultiRAE and span gas you have, you can perform a span calibration simultaneously on multiple sensors. You can define which sensors are calibrated together using the Multi Cal Select menu described in section 9.3.3.10.

In case all sensors in the instrument cannot be calibrated with the same gas, the MultiRAE will intelligently split the span calibration process into several steps and will provide menu prompts accordingly.

1. At the Calibration Menu, select “Multi Sensor Span.”

2. Install the calibration adapter and connect it to a source of calibration gas.

3. Start the flow of calibration gas.

4. Press [Y/+] to start calibrating or wait for calibration to start automatically.

5. A countdown screen is shown. You can abort the calibration at any time during the countdown by

pressing [N/-].

6. If the calibration is not aborted, the display shows the sensor names and tells you whether the

calibration passed or failed, followed by the sensor readings.

9.3.3.3 Single Sensor Zero

This allows you to perform zero (fresh air) calibration on individual sensors. Even though most toxic gas sensors can be zeroed in fresh air, sensors such as the CO2 and parts-per-billion PID sensor for volatile organic compounds (VOCs) should not be zeroed in fresh air. Both CO2 gas and VOCs are normally present in ambient air, so zeroing these sensors in ambient air will not allow for a true zero to be set for such sensors. The CO2 sensor should be zeroed in 99.9% nitrogen, and the parts-per-billion PID sensor with ambient air using a charcoal filter or a VOC zeroing tube.

1. If you are using a charcoal filter, connect it to the instrument.

2. If you are using dry air, install the calibration adapter and connect it to a source of dry air.

Note: Dotted line indicates automatic progression.

3. At the Calibration Menu, select “Single Sensor Zero.” Press [Y/+] once to enter the zero calibration

sub-menu.

4. Start the flow of dry air, if used.

5. Press [Y/+] to start zero calibration.

6. A countdown screen appears. You can abort the calibration at any time during the countdown by

pressing [N/-].

7. If the calibration is not aborted, the display shows the sensor names and tells you whether the zero

calibration passed or failed, followed by the sensors’ zero calibration readings.

9.3.3.4 Single Sensor Span

Instead of performing a span calibration on multiple sensors simultaneously, you can select a single sensor and perform a span calibration.

Note: If a calibration icon (bottle with bottom portion filled in) is shown next to any of the sensors, it means that the sensor is due for a full calibration.

To perform span calibration of an individual sensor, follow these steps:

1. At the Calibration Menu, select “Single Sensor Span.”

2. Select a sensor to calibrate from the list.

3. Install the calibration adapter and connect it to a source of calibration gas.

4. Verify that the displayed calibration value meets the concentration specified on the gas cylinder.

5. Start the flow of calibration gas.

6. Press [Y/+] to start calibrating or wait for calibration to start automatically.

Note: Dotted line indicates automatic progression.

7. A countdown screen appears. You can abort the calibration at any time during the countdown by

pressing [N/-].

8. If the calibration is not aborted, the display shows the sensor names and tells you whether the

calibration passed or failed, followed by the sensor readings.

Note: The gamma radiation sensor comes pre-calibrated from the factory and does not require routine calibration. However, you can check it by placing a check-source on the rear of the MultiRAE equipped with a gamma sensor to check the readings. There is a raised dot on the rubber boot that marks where the sensor is located inside the instrument.

9.3.3.5 MultiRAE Benzene Calibration Process

Calibrating the MultiRAE Benzene is similar to calibrating other MultiRAEs. Calibration is performed with isobutylene and benzene. Make sure the target gas is the same as the calibration gas and that it is in the correct concentration.

IMPORTANT!

 The MultiRAE Benzene must not have a RAE-Sep Tube Cartridge installed during calibration.  A filter must be attached to the inlet.  The calibration adapter must be used for calibration with both gases (isobutylene and benzene).

Note: Dotted line indicates automatic progression.

9.3.3.6 Multi Sensor Bump

Depending on the configuration of your MultiRAE and span gas you have, you can perform a bump test simultaneously on multiple sensors. Which sensors are bump tested simultaneously is defined in the Multi Cal Select menu. Refer to section 9.3.3.10 for more information.

1. At the Calibration Menu, select “Multi Sensor Bump.”

2. Install the calibration adapter and connect it to a source of calibration gas.

3. Start the flow of calibration gas.

4. Press [Y/+] to start calibrating or wait for calibration to start automatically.

5. A countdown screen is shown. You can abort the calibration at any time during the countdown by

pressing [N/-].

6. If the calibration is not aborted, the display shows the sensor names and tells you whether the

calibration passed or failed, followed by the sensor readings.

Note: Dotted line indicates automatic progression.

7. If a sensor requires different gas (such as a PID for VOCs), you are prompted. Change the calibration

gas, and when you are ready, start bump testing by pressing [Y/+].

Note: You can quit the bump calibration procedure and exit to the menu whenever you see “Quit.” Press [MODE] to quit.

9.3.3.7 Single Sensor Bump

This menu allows a bump test to be performed on an individual sensor of your choice.

Note: If a bump test icon (bottle with bottom portion not filled in) is shown next to any of the sensors, it means that the sensor is due for a bump test.

To perform a bump test on an individual sensor, follow these steps:

1. At the Calibration Menu, select “Single Sensor Bump.”

2. Scroll down the list using [N/-], and then press [Y/+] to select a sensor to calibrate.

3. Install the calibration adapter and connect it to a source of calibration gas.

4. Verify that the displayed calibration value meets the concentration specified on the gas cylinder.

5. Start the flow of calibration gas.

6. Press [Y/+] to start calibrating or wait for calibration to start automatically.

7. A countdown screen appears. You can abort the calibration at any time during the countdown by

pressing [N/-].

8. If the calibration is not aborted, the display shows the sensor names and tells you whether the

calibration passed or failed, followed by the sensor readings.

Important!

After each sensor is bump tested, and you press

“OK,” the next sensor in the menu list is highlighted. Note: Dotted line indicates automatic progression.

9.3.3.8 Cal. Reference

It is sometimes desirable to calibrate a sensor (PID for VOC, and LEL) with a specific gas for best response to a gas you are surveying. The Cal. Reference library contains calibration curves for the PID and LEL sensors for select gases. Choose the sensor, and then select from the list of reference gases.

9.3.3.9 Change Cal. Gas

You can change the calibration gas for the MultiRAE’s PID and LEL sensors. Select from a custom list that you

create (My List), the last ten gases used, the built-in gas library for your PID lamp, and user-defined custom gases. Each gas is shown in the list for selection and the screen automatically changes to show its full name, chemical formula, molecular weight (M.W.) and correction factor (CF).

9.3.3.10 Multi Cal Select

This menu allows you to define a group of sensors to be bump tested and span calibrated together. Simultaneous testing and calibration of multiple sensors shortens the bump test and calibration processes and reduces the number of individual gas cylinders you need. For example, it may be more efficient to use a single cylinder with a four-gas mix including 50% LEL Methane, 18% O2, 10 ppm H2S, and 50 ppm CO, to calibrate the LEL, O2, CO, and H2S sensors at one time, compared to using four distinct gas cylinders and calibrate these sensors individually in sequence. In order for sensors to be calibrated together, all of them must be selected using Multi Cal. Select.

1. Scroll down the list of sensors using the [N/-] key.

2. Add or remove that gas from the list by pressing [Y/+]. An “X” in a box to the left of a sensor’s

name indicates it is selected.

3. Once you have made all your selections, press [MODE] for “Done.”

9.3.3.11 Change Span Value

You can individually set the span gas concentration for each sensor. This concentration setting will also be used for a bump test. The units of measure (ppm, %LEL, etc.) are shown on the display.

1. Scroll down the list of sensors using the [N/-] key.

2. Press [Y/+] to select it.

3. Press [N/-] to step through the digits.

4. Press [Y/+] to increase the number from 0 through 9. Once the number 9 is reached, pressing

[Y/+] causes the numbers to “wrap around” to 0 and count up again.

5. Once you have set the desired value, press [MODE] for “Done.” This registers the new span value.

9.3.3.12 Change Span2 Value

If your MultiRAE is equipped with a high-range, or parts-per billion, PID sensor, you can set the span gas value for a third calibration point (Span2). The unit of measure is shown on the display.

1. Press [Y/+] to select the highlighted sensor (VOC).

2. Press [N/-] to step through the digits.

3. Press [Y/+] to increase the number from 0 through 9. Once the number 9 is reached, pressing

[Y/+] causes the numbers to “wrap around” to 0 and count up again.

4. Once you have set the desired value, press [MODE] for “Done.” This registers the new Span 2 value.

Note: Three-point calibration is disabled by default, but can only be enabled on MultiRAE and MultiRAE Pro instruments with 10.6eV PID sensors, including high-range ppm and ppb PID sensors. The MultiRAE Lite PID sensor only supports 2-point calibration.

9.3.4 Calibrating A PH3 Sensor Using H2S Calibration Gas

Using a specially designed PH3 (Phosphine) sensor in a MultiRAE with firmware version 1.50 or higher, it is possible to calibrate the PH3 H sensor using H2S (Hydrogen Sulfide) calibration gas. This simplifies both multi- and single-sensor calibration because it allows calibrating both sensors together, without requiring PH3 calibration gas.

Note: Two PH3 sensors are available, so you must use the correct one, P/N: C03-0976-100, if you want to calibrate the PH3 sensor with H2S calibration gas (or 4-mix gas containing H2S).

If the MultiRAE reads the sensor and finds that it is designed for this H2S/PH3 calibration, when you view the Multi Cal. Select screen, it shows H2S and PH3 selected. Then, if you press [N/-] to see the values of the Span gas the MultiRAE expects. Make sure that the gas values on a 4-mix calibration gas cylinder match the values shown, except for H2S, which should be 10 ppm (even though the display shows 16 ppm for PH3). To calibrate multiple sensors, including the specialized PH3 H sensor, follow the instructions on page 54.

If the MultiRAE reads the sensor and finds that it is not designed for H2S/PH3 calibration, when you view the Multi Cal. Select screen, PH3 is not selected. When you press [N/-] to advance to the values screen, PH3 is not shown.

When performing a single-sensor calibration and the instrument is equipped with the specialized PH3 H sensor, the Span Calibration screen shows the target value of the calibration gas and reminds you to apply gas using 10 ppm H2S. Follow the standard process outlined on page 55.

9.3.5 Measurement

The submenus for Measurement include Sensor On/Off, Change Measurement Gas, and VOC and Gamma (if equipped) Measurement Units.

9.3.5.1 Sensor On/Off

You can turn sensors on or off via this submenu. An “X” in a box to the left of a sensor’s name indicates it is turned on.

1. Scroll down the list of sensors using the [N/-] key.

2. Add or remove that gas from the list by pressing [Y/+]. An “X” in a box to the left of a sensor’s

name indicates it is selected.

3. Once you have made all your selections, press [MODE] for “Done.”

9.3.5.2 Change Meas. Gas

The MultiRAE has extensive onboard gas libraries for combustible gases and VOCs that you can use to configure your MultiRAE to automatically apply the appropriate correction factors and produce readings in the units of the desired combustible gas or VOC.

Measurement gases are organized in four lists:  My List is a customized list of gases that you create. It contains a maximum of 10 gases and can only

be built in ProRAE Studio II on a PC and transferred to the instrument. Note: The first gas in the list is always isobutylene (it cannot be removed from the list).

 Last Ten is a list of the last ten gases used by your instrument. The list is built automatically and is

only updated if the gas selected from Custom Gases or Library is not already in the Last Ten. This ensures that there is no repetition.

 Gas Library is a library that consists of more than 200 gases for the PID sensor and more than 50 for

the catalytic LEL sensor.

 Custom Gases are gases with user-modified parameters. Using ProRAE Studio II, all parameters

defining a gas can be modified, including the name, span value(s), correction factor, and default alarm limits.

9.3.5.3 Measurement Units

In some cases, the measurement unit for displaying data from sensors can be changed.

Standard available measurement units include:

Abbreviation

Here are two examples of menu hierarchies (select the sensor type and then the measurement unit):

9.3.6 Alarms

Use this menu to change high, low, STEL, and TWA alarm limits - the points at which alarms are triggered. The Alarms menu also allows changing alarm mode (latched or automatic reset) and alarm output methods (combinations of light, buzzer, and vibration alarm indications).

9.3.6.1 Alarm Limits

There are four groups of alarm settings that you can adjust for each individual sensor for which a particular alarm type is available.

Settings:

 High Alarm  Low Alarm  STEL (Short-Term Exposure Limit) Alarm  TWA (Time-Weighted Average) Alarm

Note: Some alarm settings are not applicable to all sensors. If a setting is irrelevant to a sensor (for example, STEL for a gamma radiation sensor), then that sensor does not appear in the list.

9.3.6.2 Alarm Mode

You can program the MultiRAE so that there are two ways to shut off an alarm:

Auto Reset

When the alarm condition is no longer present, the alarm stops automatically.

Latch

You must manually turn off an alarm when one is triggered. The latched setting only controls alarms for High Alarm, Low Alarm, STEL Alarm, and TWA Alarm.

9.3.6.3 Alarm Settings

You can enable/disable any combination of light (visible), buzzer (audible), and vibration alarms.

Settings:

 All Enabled  Light  Vibration  Buzzer  Buzzer & Light  Buzzer & Vibration  Vibration & Light  All Disabled

9.3.6.4 Comfort Beep

A Comfort Beep is a single beep of the audible alarm at 60-second intervals that informs the person using the MultiRAE that it is functioning. It can be turned on or off.

9.3.6.5 Man Down Alarm

The Man Down Alarm is a critical and potentially lifesaving feature of every MultiRAE. The Man Down Alarm is based on the premise that if the instrument is motionless when it is not supposed to be, something wrong may be happening to its user. If that is the case, a wirelessly enabled MultiRAE not only goes into alarm locally on the instrument to notify people in the vicinity, but also remotely, over a wireless network, to transmit the alarm to remote safety officers at a command center, that a person is down, so that help can be dispatched quickly.

Whenever the Man Down feature is enabled, the main screen displays a Man Down icon along the top to indicate it is active:

The MultiRAE has a 3D gravity sensor that can track the slightest motion of the instrument in any direction. If the instrument is not moved during that time, then a pre-alarm is activated to alert the user, and shows the “Are You OK?” screen. Pressing [Y/+] clears the alarm and returns the MultiRAE to its normal operation. Pressing [N/-] sets it into Man Down Alarm (and if wireless connectivity is enabled, a Man Down message is sent in real time to remote observers). If neither key is pressed, then after the countdown, it goes into Man Down Alarm (again sending a message to remote observers if wirelessly enabled).

Settings are available for:

 Off/On (off by default)  Motionless Time: time the instrument is motionless before initiating a pre-alarm (30 seconds by

default)

 Motion Sensitivity: set to low, medium, or high to compensate for ambient vibration or motion

(medium by default)

 Warning Time: countdown, in seconds, from pre-alarm to Man Down alarm (30 seconds by default)

When the Man Down pre-alarm is activated, the buzzer sounds and LEDs flash twice per second, and a countdown begins.

 If the MultiRAE’s user presses [Y/+] for “Yes” in response to the “Are You OK?” question on the

screen before the countdown reaches zero, the Man Down alarm stops and the main reading screen is displayed.

 If the person does not press [Y/+] for “Yes” in response to the “Are You OK?” question on the screen

before the countdown reaches zero, the Man Down alarm is triggered.

 If the person presses [N/-] during the countdown, answering the “Are You OK?” question with “No,”

the Man Down alarm starts.

If wireless connectivity is enabled, a Man Down message is also sent to remote observers.

IMPORTANT!

When gas or radiation alarm conditions exist at the same time as the Man Down is activated, the prealarm stage is skipped and the instrument goes straight into a Super Alarm (gas or radiation and Man Down) with four beeps/flashes per second.

IMPORTANT!

MultiRAE Benzene only: Man Down alarm capability is off during Benzene Mode measurements.

IMPORTANT!

9.3.11.14 User Mode

Two User Modes are available: Advanced and Basic. The Advanced User Mode allows a greater number of parameters to be changed than Basic User Mode. It can be used with either of the Operation Modes, Hygiene or Search. No password is required to enter the Programming Menu when in Advanced User Mode.

9.3.11.15 Backlight

The display’s backlight can be set to illuminate either automatically, based on ambient light conditions, or

manually, or it can be shut off. If manual backlighting is selected, when the backlight is turned off, pressing any key turns backlighting on. A key needs to be pressed again to perform its main function.

9.3.11.16 LCD Flip

The display can be configured to flip 180° automatically when the MultiRAE is turned upside-down. The LCD Flip feature can be set to On or Off.

Note: When LCD Flip is enabled and the instrument is inverted, the screen flips, and the button functions also “flip” so that their orientation changes, as well.

10 Policy Enforcement

The MultiRAE can be configured to enforce a facility/company’s requirements that calibration and/or bump testing be performed at specified intervals, and to explicitly prompt the user that calibration/bump testing is required. Depending on how Policy Enforcement features are configured, the user may be required to perform a bump test or calibration prior to being able to use the instrument. That is, it can be set to not allow normal operation of the instrument unless calibration or bump testing is performed.

If the instrument has been bump tested and calibrated in compliance with the policy settings, a checkmark icon is included along the top of the MultiRAE screen:

If Policy Enforcement is enabled, then after startup the MultiRAE displays a screen that informs the user that the instrument requires either a bump test or a calibration. If both are required, then they are shown in sequence.

Note: Policy enforcement features are disabled by default.

10.1 Setting Policy Enforcement

You must use ProRAE Studio II to make changes to Policy Enforcement settings. The procedure differs, depending on whether you are using an AutoRAE 2, a MultiRAE Travel Charger, or a MultiRAE Desktop Cradle. Policy violations are captured in the datalog.

10.1.1 Using The AutoRAE 2 Automatic Test And Calibration System

11 Calibration And Testing

11.1 Manual Alarms Test

Under Normal Operation Mode and non-alarm conditions, the buzzer (audible alarm), vibration, visible alarms, and backlight can all be tested anytime by pressing [Y/+] twice. If any alarm does not respond, check the alarm settings in the Programming Menu to make sure all alarms are enabled (selected setting under Programming/Alarms/Alarm Settings should be “All Enabled”). If any alarms are enabled but not functional, the instrument should not be used.

11.2 Bump Testing And Calibration

RAE Systems recommends that a bump test be conducted prior to each day’s use. The purpose of a bump test is to ensure that the instrument’s sensors respond to gas and all the alarms are enabled and functional.

 The MultiRAE multi-gas detector must be calibrated if it does not pass a bump test when a new

sensor is installed, after sensor maintenance has been performed, or at least once every 180 days, depending on use and sensor exposure to poisons and contaminants.

 Calibration and bump test intervals and procedures may vary due to national legislation and

company policy.

A bump test or calibration can be performed either manually or using the AutoRAE 2 Automatic Test and Calibration System. When a bump test or calibration is done manually, the instrument makes a pass/fail decision based on sensor performance, but the user still has the responsibility to make sure all the alarms are enabled and functional.

An AutoRAE 2 bump test or calibration takes care of both the sensor and alarm tests. Consult the AutoRAE 2 User’s Guide for details.

11.2.1 MultiRAE Equipped With A Pump

With its pump speed setting of low or high, a MultiRAE normally draws in air at a flow rate of between 200 cc/min and 300 cc/min. RAE Systems recommends that a calibration adapter used with calibration gas flow rates from 500 cc/min to 1000 cc/min.

Installing The Calibration Adapter

WARNING: Make sure the calibration adapter clips on and stays in the correct position during calibration, as illustrated below. Otherwise, the calibration adapter must be manually held in the correct position.

Wrong Wrong Wrong Correct

11.2.2 MultiRAE Lite Diffusion Model (No Pump)

Because there is no single inlet on the diffusion (non-pumped) version of the MultiRAE, a Calibration Adapter is used for supplying calibration gas to all sensors at one time. Follow these steps for attaching the Calibration Adapter.

Grasp the small handles on the Calibration Adapter.

Align the Calibration Adapter’s

two connectors with the screws

on both sides of the MultiRAE’s

gas inlets.

Make sure the connectors are securely in place before starting the flow of calibration gas. (The Calibration Adapter has small grooves on its underside to allow gas to escape after passing over the sensors.

11.2.3 Bump (Functional) Testing

A bump test can be performed on an individual sensor (Single Sensor Bump) or a group of sensors (Multi Sensor Bump) combined into Multi Cal. Select. The same gas is used for a bump test as for calibration. Typically, two cylinders of calibration gas are needed to perform a bump test or calibration on an instrument with a PID sensor and electrochemical and LEL sensors. This may require one gas cylinder with Isobutylene or another VOC test gas to test the PID sensor, and another with a 4-gas mix to test electrochemical (such as CO, H2S, and O2) and LEL sensors. As with calibration, the instrument intelligently splits the process into two consecutive steps: first, the wizard prompts for testing electrochemical and LEL sensors, and then it tests the PID sensor.

For a manual bump test, a constant-flow regulator producing 0.5 to 1 liters per minute should be used, and the calibration adapter must be installed on the instrument. Testing and calibration with an AutoRAE 2 must be performed using demand-flow regulators. A calibration adapter must not be used. Teflon tubing must be used to test or calibrate the PID sensor. Follow the steps described here to perform a manual bump test:

1. Turn on your MultiRAE by pressing and holding [MODE] (the middle button) and allow the

instrument to boot up fully until the main measurement screen with sensor names and readings is shown.

IMPORTANT!

Make sure all of the instrument’s sensors have warmed up before performing the bump test. The instrument will take the time to warm up the sensors prior to enabling access to bump test menus. You can tell a sensor has warmed up if you see a reading next to it name on the display. If it has not warmed up, you see three dashes (“---”) next to it.

Calibration Adapter

Hose to Calibration Gas Source

2. Enter the Bump Test menu. It is accessible either through Programming Menu/Calibration or

using the following easy shortcut:

With the instrument running in Normal Mode and the main measurement screen shown, press both [Y/+] and [N/-] at the same time and hold them for 5 seconds. If all the sensors have warmed up, the Multi-Bump Test menu then appears:

Otherwise, the menu appears after the warm-up is complete (while it is warming up, the screen indicates that you must wait for the sensors to warm up).

Note: If you do not apply gas within a couple of minutes, the screen changes briefly to indicate gas has not been applied, and then the instrument returns to its normal reading screen.

3. Install the calibration adapter on the MultiRAE and connect it to the calibration gas. Turn on the

gas to initiate flow.

4. Press [Y/+] to start the bump test. While the bump test is being performed, the readings for each

sensor are shown. Once the bump test completes, pass/fail test results and readings are shown for each sensor.

Note: If a PID or other sensors are installed in the instrument require a dedicated cylinder of gas to calibrate, the instrument will prompt for calibrating such sensors at this point.

5. If a PID or other sensors installed in the instrument require a dedicated gas cylinder to calibrate,

the instrument will prompt to calibrate such sensors at this point. Disconnect the gas cylinder and connect the next (for example, 100 ppm Isobutylene for a PID).

6. Press “OK” to proceed to the PID sensor test. Turn on the gas and press Start ([Y/+] button).

While the bump test is being performed, PID sensor readings are shown. Once the bump test completes, pass/fail test results and readings are shown for the PID sensor.

Note: If other installed sensors require a dedicated cylinder of gas to calibrate, the instrument prompts for calibrating these sensors at this point.

IMPORTANT!

If one or more sensors fails a bump test, be sure to calibrate those sensors.

7. The bump test is now complete. Press Exit to return to the main measurement screen.

8. Now perform a manual alarms test, as described in section 11.1.

If all the alarms and all sensors have passed and no sensor is due for a calibration, the instrument is now ready for use.

Note: When a manual bump test is performed, the readings shown are in the equivalent units of the calibration gas, and not the measurement gas (if different).

11.2.4 Testing The Gamma Radiation Sensor

The gamma radiation sensor does not require user calibration. You can check it by placing a check-source on the rear of the MultiRAE equipped with a gamma sensor to check the readings. A raised dot on the rubber boot marks where the sensor is located inside the instrument.

11.3 Zero/Fresh Air Calibration

This operation sets the zero point of the sensor calibration curve for clean air. It should be performed before other calibrations.

IMPORTANT!

Even though most toxic gas sensors can be zeroed in fresh air, sensors such as the CO2 and the parts-perbillion PID sensor for volatile organic compounds (VOCs) should not be zeroed in fresh air. Both CO2 gas and VOCs are normally present in ambient air, so zeroing these sensors in ambient air will not allow for a true zero to be set for such sensors. The CO2 sensor should be zeroed in 99.9% nitrogen and the parts-per-billion PID sensor should be zeroed with ambient air using a charcoal filter or a VOC zeroing tube.

Note: If you use a zero air or other gas cylinder, you must use the MultiRAE Calibration Adapter. A calibration adapter is not necessary for calibration in fresh air.

11.3.1 Zero Calibration For A CO2 Sensor

IMPORTANT! If your MultiRAE is equipped with a CO2 sensor, it must be zero calibrated using 100%

Nitrogen (N2), which is inert, instead of fresh air or zero air.

11.3.2 Zero Calibration For Parts-Per-Billion (ppb) Sensor

IMPORTANT! The parts-per-billion PID sensor for volatile organic compounds (VOCs) should not be

zeroed in fresh air. VOCs are normally present in ambient air, so zeroing the sensor in ambient air will not allow for a true zero to be set. The parts-per-billion PID sensor should be zeroed with ambient air using a charcoal filter or a VOC zeroing tube.

11.3.3 Fresh Air Calibration

This procedure determines zero points of most sensors. The MultiRAE should be zero-calibrated in clean air with 20.9% oxygen or with a cylinder of clean zero air.

At the Calibration menu, select “Fresh Air” by pressing [Y/+] once to enter fresh air calibration.

After a timer countdown, the zero calibration is done. The LCD displays the sensor names and tells you whether each calibration passed or failed, followed by the sensor readings.

Note: You can abort the calibration at any time during the countdown by pressing [N/-].

11.3.4 Single-Sensor Zero Calibration

Select the sensor and then start the calibration by pressing [Y/+]. You can abort the procedure anytime by pressing [N/-].

11.4 Span Calibration

This procedure determines the second point of the sensor calibration curve for the sensor.

Note: When a manual calibration is performed, the readings shown are in the equivalent units of the calibration gas, and not the measurement gas.

11.5 Three-Point Calibration For Enhanced Linearity With Extended-

Range And ppb PID Sensors

For better linearity at higher concentrations when a MultiRAE is equipped with a PID sensor, a 3-point calibration can be performed.

IMPORTANT!

Three-point calibration is disabled by default, but can be enabled using ProRAE Studio II Instrument Configuration and Data Management software on MultiRAE and MultiRAE Pro instruments with 10.6eV PID sensors, including high-range ppm and ppb PID sensors. The MultiRAE Lite PID sensor does not support three-point calibration.

Default calibration gas settings for MultiRAE PID sensors are as follows:

11.5.1 Enabling 3-Point Calibration Via ProRAE Studio II

The MultiRAE must be connected to a PC through the supplied Desktop Cradle, Travel Charger, or AutoRAE 2 and must be in the PC or AutoRAE 2 communications mode.

1. Start up the ProRAE Studio II software, enter a password, and detect the instrument following the

directions provided in the ProRAE Studio II User’s Manual.

2. Click “Setup” to download the MultiRAE’s current configuration information.

3. Click “Sensor Summary” to show the list of installed sensors.

4. Click “VOC(ppm)” or “VOC(ppb)” to get and set sensor parameters.

5. Click 3-Point Calibration (the check mark should now be showing).

6. Click the “Upload all settings to the instrument” icon. You will be asked whether you want to

upload all configurations to the instrument. Click “Yes.”

7. When you are done, quit ProRAE Studio II and then press [Y/+] on the MultiRAE to exit the PC

communications mode. The instrument returns to operating in Normal mode.

11.5.2 Multi-Sensor Span Calibration

This lets you perform a span calibration on multiple sensors simultaneously. It requires using the appropriate span gas and that the concentration labeled on the gas cylinder matches the concentration programmed in the MultiRAE.

For a multi-sensor span calibration, a constant-flow regulator producing 0.5 to 1 liters per minute should be used, and the calibration adapter must be installed on the instrument. Testing and calibration with an AutoRAE 2 must be performed using demand-flow regulators. A calibration adapter must not be used. Teflon tubing must be used to test or calibrate the PID sensor. Follow the steps described here to perform a multi-sensor span calibration:

1. Attach the calibration adapter and connect gas to the MultiRAE.

2. Start the flow of gas and then either press [Y/+] to begin calibration or wait for calibration to start

automatically once the sensor “senses” the gas. A countdown screen is shown. You can abort the calibration at any time during the countdown by pressing [N/-].

If the calibration reaches its conclusion, it shows the sensor names and tells you whether the calibration passed or failed, followed by the sensor readings.

Note: If there are other sensors to be calibrated at this stage, the screens will guide you through the process.

11.5.3 Single-Sensor Span Calibration

To perform span calibration of an individual sensor, follow these steps:

1. At the Calibration Menu, select “Single Sensor Span.”

2. Select a sensor from the list.

3. Connect the calibration adapter and connect it to a source of calibration gas.

4. Verify that the displayed calibration value meets the concentration label on the gas cylinder.

5. Start the flow of calibration gas.

6. Press [Y/+] to start calibrating. You can abort the calibration at any time during the countdown by

pressing [N/-].

After a timer countdown, the span calibration is done. The LCD will display whether the calibration was successful and the reading for that calibration gas.

Note: If the sensor calibration fails, try again. If calibration fails repeatedly, turn off the instrument and then replace the sensor.

WARNING: Do not replace sensors in hazardous locations.

12 MultiRAE Pro Normal & Gamma Operation

MultiRAE Pro monitors equipped with a gamma radiation sensor in addition to one or more sensors for detecting chemical threats can operate in two different measurement modes:

 Normal mode, in which the instrument monitors for both chemical threats and radiation

simultaneously

 Radiation-only mode, in which the instrument continuously monitors for gamma radiation and

does not monitor for chemical threats

The specifics of each operating mode are described in the following sections.

12.1 Normal Mode For Simultaneous Radiation & Gaseous Threat

Measurements

Normal mode is the default mode of MultiRAE Pro’s operation. It is only available on MultiRAE Pro monitors equipped with a gamma radiation sensor, provided the gamma sensor is enabled. The minimum instrument firmware requirements for the gamma sensor are:

 Application firmware: v.1.16 or higher  Sensor firmware: v.1.06 or higher

When the monitor is turned on, it boots up in normal mode to monitor for both gamma radiation and gaseous threats. Measurements are done continuously.

12.2 Gamma Radiation-Only Measurement Mode

When the instrument is in gamma-only mode, gas sensors are not shown on the display and gas measurements are not taken. The pump remains off and gamma radiation is measured all the time.

WARNING

Toxic and combustible gases cannot be detected by the MultiRAE when it is operated in gammaonly mode.

12.2.1 Activating Gamma-Only Measurement Mode

To activate gamma-only measurement mode:

1. Press [N/-] when the instrument is running in normal (multi-threat) mode:
