Approved Models of the Multi-PID 2

This manual provides operational information for all models of the Multi-PID 2. The Multi-PID 2 is intrinsically safe and approved for use in hazardous locations. Refer to the Notices and Warnings section of this manual for details of each approval.

Throughout the manual, notes are provided to inform you of any limitations of usage for the Multi-PID 2 models.

WARNING: If the Multi-PID 2 you are using is not speciﬁcally identiﬁed as intrinsically safe with a label on the Multi-PID 2, do not use it in a location where ﬂammable concentrations of gases and vapors may exist.

Introduction

Excessive Heat and Cold

WARNING: Do not expose the instrument to intense sunlight for prolonged periods. Exposure to excessive heat or cold may result in erroneous readings.

Introduction

Intended Use

The Multi-PID 2 measures the concentration of airborne gases and vapors that can be ionized by a photoionization detector. The Multi-PID 2 automatically displays and can record these concentrations.

In the TVOC mode the Multi-PID 2 does not distinguish between individual compounds.

The reading displayed represents the total concentration of all photoionizable chemicals present in the sample. The Multi-PID 2 is factory-set to display concentration in units of ppm.

Benzene is selectively measured in GAS mode.

This measurement requires the use of the PID pre-ﬁlter tube benzene. The pre-ﬁlter tube adsorbs all substances with the exception of benzene. Only benzene passes into the detector.

The Multi-PID 2 operates automatically. The Multi-PID 2 display updates itself once per second. You can read concentrations directly from the display. The Multi-PID 2 will perform short-term exposure limit (STEL), timeweighted average (TWA) and REAL calculations when it is in INTERVAL mode. You can view any of these results in INTERVAL mode.

The Multi-PID 2 has two datalogging options, TAG and INTERVAL mode. TAG mode allows the user to manually tag and store readings during a walkthrough. Interval mode allows the user to datalog at selectable intervals of 3 seconds to 900 seconds. In INTERVAL mode, the STEL, REAL and TWA are calculated. If you select INTERVAL mode, these values are automatically recorded in the Multi-PID 2’s memory. The Multi-PID 2 can log up to 12,000 entries.

In TAG mode operation, the Multi-PID 2 prompts you to locate a site and then to record a background and sample readings for the site. You can record up to 12,000 manual entries. There is no averaging of data in TAG mode. Tags are set via the PC using the Dräger GasVision software.

Introduction

Recorded data can be reviewed on the display or downloaded to a computer. Data are recorded by date and time.

The Multi-PID 2 has 5 keys for instrument operation. The keys are used to set up and calibrate the Multi-PID 2. All information entered with the keys and stored in the Multi-PID 2’s memory is retained when the instrument is switched off. The clock and calendar continue to operate and do not need to be reset when the Multi-PID 2 is turned on.

Introduction

General Operation

The Multi-PID 2 is a microprocessor-controlled air monitor for measuring the presence of photoionizable compounds in air at parts-per-million levels. The block diagram in Figure 2 shows the main components of the Multi-PID 2.

Figure 2 – Multi-PID 2 Block Diagram

The microprocessor controls the components of the instrument and interprets and records the signal generated by the photoionization detector (PID). Recorded data and setup information entered into the microprocessor’s memory are retained when the Multi-PID 2 is turned off.

A pump continuously pulls the air under test through the Multi-PID 2’s PID. The Multi-PID 2 converts the concentration of photoionizable compounds in the sample into an electrical signal. The microprocessor subtracts any background from the signal and divides this signal by a sensitivity obtained by calibrating with a standard gas of known concentration. This concentration appears on the Multi-PID 2’s display and, depending on the values entered through the Multi-PID 2’s keypad, an alarm status may be displayed and an audio signal may be heard.

Gas Connections

00623958_01_en.eps

The Multi-PID 2 can detect thousands of different types of airborne gases and vapors and its response depends on the characteristics as well as the concentration of each compound.

The Multi-PID 2 does not distinguish one type of compound from another, but displays a number indicating the total concentration of all photoionizable compounds in the sample.

A standard of isobutylene at a known concentration may be used for setting the sensitivity. If the Multi-PID 2 is calibrated with isobutylene, it displays concentrations in units equivalent to ppm of isobutylene. If isobutylene were the only photoionizable chemical in the sample, then the Multi-PID 2 would display its concentration directly.

The Multi-PID 2 responds more or less readily to other chemicals than it does to isobutylene. Because it has a medium sensitivity to isobutylene, this gas has been chosen as a reliable means of reporting an average concentration of total ionizable compounds present.

Gases other than isobutylene can be used to calibrate the MultiPID 2. However, all response factors are based on an isobutylene calibration.

Introduction

Photoionization Detector

The photoionization detector (PID) is shown in Figure 3. The PID measures the concentration of photoionizable chemicals in the gas stream from the sample inlet and produces an electrical signal for the microprocessor.

A UV lamp generates photons which ionize speciﬁc molecules in the gas stream. The permanent air gases (argon, carbon dioxide, nitrogen, oxygen, water vapor, etc.) require a relatively high energy for ionization, and are not ionized by the UV photons. Many of the compounds considered pollutants, including most hydrocarbons, are ionized.

The gas stream is directed into the PID through a small port at the center of the UV lamp window and through a series of larger ports around the perimeter of the lamp window. This arrangement permits a high sample ﬂow rate and short response time.

Ionized Molecule

The ionized molecules in the detector cell are subjected to the electric ﬁeld between the electrodes. This generates a current which is proportional to the concentration of the ionized molecules in the detector cell. An ampliﬁer converts the current to a voltage which is then fed to the microprocessor.

00723958_01_en.eps

The UV lamp is operated by a high voltage lamp driver circuit which injects its energy through plates in the lamp holder. The lamp driver power supply is controlled by the microprocessor based on a feedback signal from a light sensor on the driver circuit board.

Introduction

Support Equipment and Consumables

Calibration

For normal operation these items are required:

1. Calibration Gas Regulator (Part No. 68 10 688).

2. Calibration gas containing 100 ppm isobutylene (Part No. 68 10 687). Other concentrations of the calibration gas may be required. This will depend on your application.

3. Zero air (clean dry air without any organic impurities) There are several alternatives for clean or zero air calibration: you

can use a bottle of clean air (certified as having not more than

0.1 ppm total hydrocarbons) connected directly to the instrument; the clean air can be transferred to a Tedlar bag which can then be connected to the instrument; clean, ambient air without detectable contamination; or, ambient air run first through the charcoal filter (Part No. CH 24 101).

4. If compound threshold limit values (TLVs) are exceeded, you should use a gas bag for sampling and calibration.

To determine the TLV of the compounds contained in the calibration gas, refer to the Material Safety Data Sheet (MSDS) supplied with your calibration gas cylinder.

Field Operation

For ﬁeld operation, the Multi-PID 2 Field Kit (Part No. 83 17 663) is available. The ﬁeld kit includes a cable kit, a carrying case and a calibration regulator, and a spare battery pack.

1. If the Multi-PID 2 has been turned on, turn it off by pressing the ON/OFF key for five seconds and then releasing it.

NOTE: If you do not turn the Multi-PID 2 off before removing the battery pack, you will reset the instrument and you will lose all logged data and setup parameters.

2. Locate the battery hatch on the back of the instrument. See Figure 4.

3. Loosen the two Phillips screws in the top of the battery hatch.

4. The battery hatch can now be removed.

5. Lift the battery pack out of the case and carefully disconnect the battery pack connector from the Multi-PID 2.

6. Attach the connector from the charged battery pack to the Multi-PID 2.

NOTE: The connector is polarized. It will only ﬁt one way. Do not force the connection.

7. Place the battery pack in the Multi-PID 2 case. Ensure the battery wires are not pinched or strained.

8. Ensure the wrist strap ring is in proper position. This ring holds the wrist strap in place.

9. Replace the battery hatch and then replace the two screws. Do not overtighten the screws as you will damage the case.

Charging the Battery Pack

NOTE: Only use the AC adapter speciﬁed for use with the Multi-PID 2. Using another AC adapter will result in damage to the battery pack, the Multi-PID 2 or the adapter itself.

To charge the battery pack:

1. Plug the AC adapter into the jack located on the bottom of the Multi-PID 2.

2. Plug the AC adapter into an AC outlet. If you are using the European AC adapter, ensure the correct plug is installed on the line cord. If it is not correct for the wall outlet in your area, then it must be replaced.

3. The Charge LED on the Multi-PID 2 indicates the charge state. Red indicates the battery is being charged. Green indicates the battery is fully charged and ready for use. It is normal for a fully charged battery to indicate it is charging (red light) when first plugged in. The Charge LED will turn green within a few minutes to indicate the battery is fully charged.

4. When the battery pack is fully charged, remove the AC adapter first from the wall outlet and then from the Multi-PID 2.

Using the Multi-PID 2

Figure 4 – Battery Pack Removal and Replacement

00823957_01_de.eps

Using the Multi-PID 2

Charging a fully discharged battery pack will take approximately 4 hours.

Optionally you can use the off line charger (Part No. 64 05 404) to charge the battery pack when not installed in the Multi-PID 2.

If you are charging the battery pack in the instrument you can use all the features of the Multi-PID 2 while the battery pack is being charged.

Leaving the AC adapter connected to the Multi-PID 2 will not harm the battery or the AC adapter in any way. If the Multi-PID 2 is to be left unused for an extended period of time, leave it connected to the AC adapter so that the battery will be fully charged and ready for operation.

On average a fully charged battery pack will provide 8 hours of continuous operation. Battery life is shorter if the instrument is turned off and then on again repeatedly, or if the backlighting is turned on.

Display

The Multi-PID 2 has a graphic display for reporting detected concentration and to guide you through conﬁguration options. All functions of the Multi-PID 2 will be reported on the display.

Graphic Display

The Multi-PID 2 uses an 8 line graphic display. The display will always be used for reporting detected concentration. In order to accommodate the range of concentrations the Multi-PID 2 can detect, the meter reading will be reported using one of two resolutions. A resolution of 0.1 ppm will be used for concentrations below 100 ppm, and a resolution of 1 ppm will be used for concentrations above 100 ppm .

Keys

Fixed Keys

The Multi-PID 2 has two ﬁxed keys. The ﬁrst ﬁxed key is the -key (on/off). The second ﬁxed key is the dedicated -key (calibration key). Pressing the -key will start calibration in almost any mode.

CAL

The -key is used to both turn power on to the Multi-PID 2 as well as the turn the power off. To turn on the Multi-PID 2, press the key. To turn the power off, press the -key and hold it down for 5 seconds, and then release it. This is done to prevent accidental power off.

Soft Keys

The three soft keys on the Multi-PID 2 are located directly below the display. Each key has varying functions for conﬁguring the Multi-PID 2, editing the data, and controlling the display. Since only three soft keys are available, each function is broken down into a path.

CAL

Beginning Operation

Turning the Multi-PID 2 On

1. Turn the Multi-PID 2 on by pressing the -key.

2. The Multi-PID 2 will display the instrument’s software version number. Next the Multi-PID 2 will proceed to the mode display.

3. The Multi-PID 2 has an instant-on lamp. For maximum accuracy and stability, allow the Multi-PID 2 to warm-up for 10 minutes prior to calibration.

Default Display

The display shows the last mode the Multi-PID 2 used. The resolution of the display changes with the magnitude of the reading. A reading of 0 to 99.9 will be displayed with a resolution of 0.1 ppm. A reading greater than 99.9 will be shown with a resolution of 1 ppm. The meter will display concentrations up to 2,000 ppm.

GAS mode:

In GAS mode, the PID pre-ﬁlter tube benzene (Order No. 81 03 511) can be used to measure benzene, or a sample collection tube (Order No. 67 33 011) can be ﬁlled with a deﬁned amount of a sample. The GAS mode is a ﬁlter tube mode. This means that all measurements require the installation of the pre-ﬁlter tube holder (83 10 093) and of the pre-ﬁlter tubes. The PID pre-ﬁlter tube benzene which is mounted at the head end of the tube holder and adsorbs all substances with the exception of benzene is used to selectively measure benzene. The entire process is menu-driven. The selective benzene measurement value is displayed after 90 seconds. Activating the GAS mode opens a dialog which queries a device calibration. The benzene measurement screen is displayed after installation of the PID pre-ﬁlter tube benzene.:

So the displayed number shows the remaining measuring time. " SAMPLE DONE " signalled in the display indicates that the measurement is ﬁnished. The PID pre-ﬁlter tube benzene is a one-shot-device and cannot be used for a second measurement. Repeatedly pressing the " sample " key will call up the information that the PID pre-ﬁlter tube benzene in use is no good and that a new PID pre-ﬁlter tube benzene must be put into the pre-ﬁlter tube holder. Only after inserting a new tube will pressing the " sample " key start a new measurement.

System Alerts and Alarms

While operating the instrument, system alerts can occur. To accurately identify the source of the alarm, each type of alarm has been given a unique status.

In addition to the status, the Multi-PID 2 also has an audio alarm and an alarm LED. To conserve power, the Multi-PID 2 alternates between the LED and audio. Different alarms are identiﬁed by the frequency at which the Multi-PID 2 alternates between the audio and LED; REAL alarm is 5 times per second, STEL alarm is 2.5 times per second, and TWA alarm is 1.25 times per second.

Using the Multi-PID 2

A soft key is used for acknowledging alarms and is named “ accept ”. If no alarm exists, then the “ accept ” key is not shown. To clear the alarm, press the “ accept ” key. Once acknowledged, the alarm indi- cators are cleared. The alarm status will remain until the alarm condition clears.

The Multi-PID 2 updates the instantaneous concentration once every second. Following every update, the instantaneous concentration is compared to the REAL alarm level, and if exceeded, an alarm is triggered.

In Interval mode, if a 15-minute average exceeds the STEL, a STEL alarm is generated. The TWA alarm is generated when the current average of concentration, since the TWA was last cleared, has exceeded the TWA exposure limit.

During calibration, all alarms are disabled. Once the calibration is complete, the alarms are re-enabled.

Short-Term Exposure Limit (STEL) Mode

The Short-Term Exposure Limit (STEL) mode displays the concentration as a 15-minute moving average. The Multi-PID 2 maintains 15 samples, each representing a one-minute averaging interval.

Once every minute, the oldest of the 15 samples is replaced with a new one-minute average. This moving average provides a 15-minute average of the last 15 minutes with a one-minute update rate. Since the average is calculated using 15 one-minute averages, the meter display will only update once every minute. STEL is set to zero each time the instrument is turned on. Since STEL is a 15-minute moving average, there is no need to clear or reset the STEL. STEL calculations are always being performed by the Multi-PID 2. You can display the results of the calculations by selecting Interval Mode.

Time-Weighted Average (TWA) Mode

The TWA accumulator sums concentrations every second until 8 hours of data have been combined. If this value exceeds the TWA alarm setting, a TWA alarm is generated. The TWA is not calculated using a moving average. Once 8 hours of data have been summed, the accumulation stops. In order to reset the TWA accumulator, press the " clear " key, then select » TWA « using the " " clear ".

This sum will only be complete after 8 hours, so the meter displays the current sum divided by 8 hours.

TWA calculations are always being performed by the Multi-PID 2. You can display the results of the calculations by selecting Interval mode.

l " key, then press

Using the Multi-PID 2

REAL Mode

The REAL mode displays the current detected concentration. The reading is updated once a second. In the background, the Multi-PID 2 datalogger is sampling the concentration and measuring minimum, maximum, and average concentrations for the selected averaging interval. At the end of every interval, one entry is placed in the datalogger until the datalogger is full.

In order to reset the REAL reading, press the " clear " key then select » REAL « using the "

11.7 eV UV Lamp

General Information

The Multi-PID 2 is equipped with a standard 10.6 eV UV lamp. An

11.7 eV UV lamp (Part No. 83 18 317) is available for special applications. Install this lamp as outlined in Removing and Replacing the UV Lamp on page 80. When you install a UV lamp other than the standard

10.6 eV lamp, all the response factors become invalid. You must set the response factor for the current cal memory to 1. Contact Dräger Safety’s Applications Department for further information.

NOTE: Do not use the 11.7 eV lamp in conjunction with the dilution probe.

Limitations of Lithium Fluoride Lamp Window

This lamp is intended for special applications only. It is not suitable for normal operation, due to limitations of the lamp window material.

The 11.7 eV lamp window material is lithium ﬂuoride (LiF). LiF is composed of two light elements which are easily disrupted within the crystal lattice by the UV light generated by the lamp. Disruption of the lattice causes the crystal to turn a yellowish color, and again performance declines.

Unlike other lamp windows, LiF readily absorbs water from atmospheric humidity. When contaminated by moisture, the window loses its ability to transmit UV light.

WARNING: Do not touch the lamp window or handle it near water.

Using the 11.7 eV UV Lamp

With an 11.7 eV lamp installed, your instrument functions as a detector responding to compounds which ionize at 11.7 eV or less. The

11.7 eV lamp may be useful for detecting compounds not ionized by the standard 10.6 eV lamp.

Due to the lamp window limitations, the lifetime of the 11.7 eV lamp is restricted and it must be used sparingly according to the following instructions.

To use the 11.7 eV lamp in your the Multi-PID 2:

1. Remove the 11.7 eV lamp from the supplied desiccant bottle and install the lamp as outlined in Removing and Replacing the UV Lamp on page 80.

WARNING: Do not remove or replace any detector lamp in a hazardous location, danger of an explosion!

2. Turn the instrument on and wait for the ready status. If the lamp cannot be started, contact Dräger Safety’s Technical Support Department.

3. Calibrate the Multi-PID 2. See Calibration Using the Flow-Match Regulator on page 76.

4. All response factors are invalid when an 11.7 eV lamp is installed. The response factor must be set to 1.

5. Recalibrate the instrument every 15 minutes of operation.

6. Every hour of operation, switch off the instrument, remove the lamp and examine the window for yellowing. If the window is yellow, then regenerate the window according to the procedure in Cleaning the Lithium Fluoride Window on page 83.

7. After use, remove the lamp and store it in the supplied desiccant bottle.

Do not leave the 11.7 eV lamp in the instrument when you turn it off. Always remove the 11.7 eV lamp and store it in the supplied desiccant bottle

The Multi-PID 2 is designed for ease of use with a logically organized internal menu structure/user interface. The Multi-PID 2 User Menu is shown in Figures 6 and 7 on page 30 and page 31.

The Multi-PID 2 has three soft keys under the graphic LCD display which always show the available functions of the soft keys in any screen.

Operation Modes

GAS mode

The GAS mode is a ﬁlter tube mode. This means that all measurements require the installation of the pre-ﬁlter tube holder and of the pre-ﬁlter tubes. In this selective measuring mode, the PID pre-ﬁlter tube benzene which is mounted at the head end of the pre-ﬁlter tube holder and adsorbs all substances with the exception of benzene is used to selectively measure benzene. The entire process is menudriven. The selective benzene measurement value is displayed after 90 seconds.

Activating the GAS mode opens a dialog which queries a device calibration. The benzene measurement screen is displayed after installation of the PID pre-ﬁlter tube benzene. The following values are displayed: benzene concentration in xx ppm, STEL value, the highest benzene measurement value recorded so far (SMAX), the amount of measurements already carried out (SAMP) – corresponds with the amount of PID pre-ﬁlter tube benzene already used, and the sampling interval period of 90 seconds (SECS). Pressing the " view " key shows the Datalogger measurement values. Pressing the " menu " key takes you back to the selection menu. Pressing the " sample " key starts the measurement: the pump is activated and the measured air is drawn through the PID pre-ﬁlter tube benzene for 90 seconds. The measurement status is indicated by the ﬂashing concentration value and by the ﬂashing word " sampling ". The number 90 displayed under SECS counts down to 0. So the displayed number shows the remaining measuring time. " sample done " signalled in the display indicates that the measurement is ﬁnished. The PID pre-ﬁlter tube benzene is a one-shot-device and cannot be used for a second measurement. Repeatedly pressing the " sample " key will call up the information that the PID pre-ﬁlter tube benzene in use is no good and that a new PID pre-ﬁlter tube benzene must be put into the pre-ﬁlter tube holder.

» Interval «

Interval displays the instantaneous readings as well as STEL, TWA, and REAL readings. Interval mode is identiﬁed by the letters » INT « in the upper right-hand corner of the Multi-PID 2 display. Interval automatically calculates and updates STEL, TWA, and REAL readings. Interval mode also automatically stores these readings in the Multi-PID 2’s memory at a preset interval selected by the user. In interval mode data is logged at a user selected interval value between 3 seconds and 900 seconds. The microprocessor accumulates all readings in an averaging interval that you select, and determines the minimum, average and maximum readings. It stores these numbers along with the highest priority instrument status and the most recent time and date. These recorded data can now be reviewed and edited. Recorded data can also be printed using the PC. For each averaging interval, the Multi-PID 2 prints the minimum of all the minima, the average of all the readings for the interval and the maximum of all the maxima.

Menu Functions

In STEL mode, 15 samples are combined to form a 15-minute average. Once every minute, the oldest of the 15 samples is replaced with a new one-minute average. This moving average provides a 15-minute average with a one-minute update rate so the meter display will only update once every minute. STEL is set to zero each time the instrument is turned on. STEL calculations are always being performed by the Multi-PID 2. You can display the results of the calculations by selecting STEL as the Display mode.

In REAL mode, the reading is updated once a second. In the background, the Multi-PID 2 datalogger is sampling the concentration and measuring min, max, and average concentrations for the selected averaging interval. At the end of every interval, one entry is placed in the datalogger until the datalogger is full.

TWA mode sums concentrations every second until 8 hours of data have been accumulated. Once 8 hours of data have been summed, the accumulation stops. This sum will only be complete after 8 hours, so the meter displays the current sum divided by 8 hours. While you are in TWA mode, the time on the status display will show the number of minutes and hours of data that TWA has accumulated. When this reaches 8 hours, the Multi-PID 2 stops accumulating data and the TWA is complete. TWA calculations are always being performed by the Multi-PID 2. You can display the results of the calculations by selecting TWA as the Display mode. Interval mode logs readings at user-selected intervals of 3 seconds to 900 seconds.

General Information

The response of a PID to a compound is dependent on its ionization potential. In certain situations when the user is conﬁdent that only a single speciﬁc compound exists, they can set up the Multi-PID 2 using an isobutylene calibration to mimic the Multi-PID 2 response as if the Multi-PID 2 was calibrated using that speciﬁc single compound. In situations where only a single pure compound is present in air, the Multi-PID 2 should be calibrated with a standard of that speciﬁc compound as span gas.

Menu Functions

NOTE: In the case of calibration or when changing the conﬁguration, the data logger has to be deleted manually to ensure consistant data.

The Multi-PID 2’s 15 memory slots can be used to store calibration information for 15 different span gases. The Multi-PID 2 will always detect all ionizable compounds present in a sample regardless of the response factor (RF) selected.

NOTE: Even if the Multi-PID 2 has been calibrated with a speciﬁc compound, its response is not speciﬁc and the presence of another ionizable impurity may render the numerical result invalid.

It is often impractical to carry a range of different standards into the ﬁeld. Approximate results can be obtained by calibrating the MultiPID 2 with the recommended span gas and entering the appropriate response factor. The response factor is based on the ratio of the response of the speciﬁc compound to the response of the span gas. The response factor multiplies the Multi-PID 2’s reading, then displays and records it. See table 5 on page 97 for response factors. This list should be used only for concentrations up to 500 ppm of the speciﬁc compound, as response factors change with concentration.

WARNING: The Multi-PID 2 is a total VOC instrument and will ALWAYS respond to all ionizable compounds present in a sample. The Multi-PID 2 will NEVER respond only to a speciﬁc compound if an RF is programmed. It is the responsibility of the user to be aware of the limitations of PID instruments

Routine Maintenance

Maintenance Intervals

The device should be calibrated before measuring, especially if it was not used for a longer period of time.

If used, the 11.7 eV lamp should be replaced approx. every six months.

Calibration Technical Description

Periodic calibration is required to compensate for the Multi-PID 2 output changes due to inlet ﬁlter restriction, ionization chamber contamination, lamp cleanliness, pump wear and other factors.

During calibration, the Multi-PID 2 is ﬁrst exposed to zero air. A small (zero) signal is generated. This zero signal is stored by the microprocessor.

The Multi-PID 2 is next exposed to span gas. This span gas signal is stored by the microprocessor. The microprocessor subtracts the zero signal from the span gas signal and divides the difference by the userentered span gas concentration. The resulting sensitivity is stored in the selected Memory Slots with the zero signal and the alarm levels. This number is then multiplied by the response factor and displayed.

The Multi-PID 2 readings are always relative to the calibration gas. After calibration with isobutylene, the Multi-PID 2 will respond directly in units equivalent to isobutylene. Most volatile organic compounds will be detected by the Multi-PID 2. It cannot distinguish between isobutylene and other ionizable compounds. A reading of 10 ppm indicates all ionizable compounds that are present have generated an ion current proportional to 10 ppm of isobutylene. The reading is actually 10 ppm isobutylene equivalent units. The Multi-PID 2 readings give an indication of the total ionizables present and their concentration relative to the calibration gas.

NOTE: During calibration, all storage places are always calibrated simultaniously. Isobutene is expected as a calibration gas and the concentration is corrected via the response factors. Please refer to chapter “Memory slots Menu” on page 65. for a target gas calibration.

Calibration Introduction

The Multi-PID 2 must be calibrated in order to display concentration in ppm units equivalent to the calibration gas. First, a supply of zero air, which contains no ionizable gases or vapors, is used to set the Multi-PID 2’s zero point. Then, a calibration gas, containing a known concentration of a photoionizable gas or vapor, is used to set the sensitivity.

Clean indoor ambient air may be substituted for a cylinder of zero air. Due to the Multi-PID 2’s sensitivity, outdoor air is usually unsuitable for calibration unless the activated charcoal ﬁlter (Part No. CH 24 101) and ﬁlter tube holder (Part No. 83 19 093) is used.

Commercially sourced zero air should not have more than 0.1 ppm total hydrocarbons (THC).

To determine the TLV of the compounds contained in the calibration gas, refer to the Material Safety Data Sheet (MSDS) supplied with your calibration gas cylinder.

NOTE: Disconnect the Multi-PID 2 from the AC adapter before beginning calibration.

Routine Maintenance

NOTE: In the case of calibration or when changing the conﬁguration, the data logger has to be deleted manually to ensure consistant data.

Routine Maintenance

Compressed Gases

Cylinders of compressed gas, such as calibration gas, must be handled with extreme care. For safety, the calibration gas cylinders must be secured before use.

Please observe the following handling procedures:

● Mark each new regulator with its intended gas service and never

use a regulator for more than one service. To ensure safety and avoid contamination, regulators should be dedicated to one service. Do not change gas service or adapt equipment without consulting your gas supplier.

WARNING: Do not heat or expose cylinders or regulators to temperatures above 52

C (125 oF). The cylinders

may rupture at high temperatures!

● Use only the specified regulator for the calibration gas. Confirm re-

gulator type and material with your specialty gas supplier.

● Always secure cylinders before removing the cylinder valve protec-

tion cap.

● Do not drag or roll cylinders. Large cylinders should only be mo-

ved on carts designed for compressed gas cylinders. Do not move cylinders without the valve protection cap in place.

● Wear safety glasses when working with compressed gases.

● Do not store cylinders in a hazardous location. Store cylinders in

an upright position away from possible sources of heat or sparks.

● Never plug, obstruct or tamper with safety relief devices.

Regulators for Compressed Gases

When connecting a regulator to a large cylinder:

● Ensure cylinder valve and regulator connection match.

● Ensure regulator construction materials are compatible with the

gas, and that the cylinder pressure gauge will withstand the cylinder pressure.

● Never use the regulator as a shut-off valve. Close the cylinder

when it is not in use.

● Do not subject the regulator to an inlet pressure greater than re-

commended.

● Do not move or detach the regulator when it is pressurized or

when it is in use.

● Before connection, ensure the gas cylinder valve and the regulator

CGA connection are clean.

● Turn the pressure control valve on the cylinder all the way off (clo-

se the cylinder). Turn the regulator outlet to off. Open the gas cylinder valve slowly and check for leaks. Adjust the delivery pressure and then open the regulator outlet valve.

Calibration Gas

Adequate ventilation must be provided when the Multi-PID 2 is being calibrated.

If compound threshold limit values (TLV) are exceeded, you should use a gas bag for sampling and calibration.

To determine the TLV of the compounds contained in the calibration gas, refer to the Material Safety Data Sheet (MSDS) supplied with your calibration gas cylinder.

Routine Maintenance

Calibration Using the Flow-Match Regulator

Connecting the Flow-Match Regulator to the Cylinder

WARNING: Observe proper handling procedure for all gases!

To connect the ﬂow-match regulator to the gas cylinder:

1. Connect the regulator to the calibration gas cylinder.

2. If you are using a portable tank of calibration gas (Part No. 68 10 687), connect the regulator (Part No. 68 10 688) directly to the tank.

3. When the regulator is connected properly, you can read the cylinder contents from the regulator gauge.

4. Connect the adapter tubing to the regulator.

5. Check if the Multi-PID 2 is sucking in the gas pressure free, e.g. by means of a T-piece; paying attention the fact that the flow from the gas cylinder is higher than the inlet flow of the Multi-PID 2.

Routine Maintenance

Battery Charging

A fully charged battery pack powers the Multi-PID 2 for approximately 5,5 hours. If the instrument is to be used for more than 5,5 hours, carry a spare battery pack (Part No. 83 23 622 or 83 17 670). When the ﬁrst one has been discharged, replace it with the spare.

NOTE: If you do not turn the Multi-PID 2 off before removing the battery pack, you will reset the instrument and you will lose all logged data and setup parameters.

When the Multi-PID 2 displays the low battery symbol, the battery pack requires charging. When the low battery symbol is displayed, you have 30 minutes of operation left. The Multi-PID 2 will turn itself off before the battery pack becomes critically low.

WARNING: Do not remove or recharge the battery pack in a hazardous location.

Upon return from ﬁeld work, charge the battery packs as outlined in Battery Charging on page 26. Use only the AC adapter speciﬁed for use with the Multi-PID 2. Optionally you can use the off-line charger to charge the battery pack independently of the instrument. See OffLine Charger on page 50.

NOTE: You must use the 220 V battery charger (Part No. 83 17 661) in order to comply with the requirements of the applicable Council Directives.

If you do not require portable operation, you can use the Multi-PID 2 while it is connected to the AC adapter.

WARNING: The Multi-PID 2 is not intrinsically safe when connected to an AC adapter.

When the Charge LED on the top of the Multi-PID 2 is red, the battery is charging. When the Charge LED turns green, the battery is fully charged.

Battery Pack Care

Leaving the Multi-PID 2 for more than 3 months without charging the batteries may result in the loss of recorded data and setup parameters. If the Multi-PID 2 is not used for long periods of time, recharge the battery for a few hours every 30 days to avoid loss of data. See Battery Charging on page 26 for instructions on charging the battery.

Please observe the following:

● For replacement battery pack use only Part No. 83 23 622 or

83 17 670.

WARNING: Do not dispose of the battery pack in a ﬁre. The cell may explode!

● This battery pack must be disposed of properly. Check with local

codes for special disposal instructions.

● Do not open or mutilate the battery pack.

WARNING: Exercise care in handling battery packs in order not to short the terminals with conducting materials such as rings, bracelets and keys. The battery or conductor may overheat and cause burns.

● Charge the battery pack using the AC adapter provided with or

identified for use with this product only in accordance with the instructions and limitations specified in this manual. For AC adapter use only Part No. 64 05 428 (North America) or Part No. 83 17 661 (Europe).

Maintenance of the UV Lamp

Removing and Replacing the UV Lamp

WARNING: Do not remove or replace the UV lamp in a hazardous location, danger of an explosion!

To remove the UV lamp from your instrument:

1. Ensure the instrument is turned off.

WARNING: You must turn the instrument off before removing the lamp cover.

2. Remove the lamp housing cover.

3. Tilt the Multi-PID 2 slightly and remove the UV lamp.

WARNING: Do not touch the wire grid inside the detector cell. Any dust or dirt in the detector cell can be blown out with a gentle jet of compressed air.

Do not insert any object, other than the UV lamp, into the lamp holder.

4. Without touching the lamp window, place the new lamp into the Multi-PID 2 lamp holder, window first. See Figure 19.

NOTE: Do not force the lamp into the lamp holder.

5. Replace the lamp housing cover. Tighten the cover down. Do not over tighten.

6. Calibrate the Multi-PID 2 and then continue normal operation.

Routine Maintenance

Cleaning the UV Lamp Window

During the course of normal operation, a ﬁlm builds up on the window of the UV lamp. The rate at which the ﬁlm develops depends on the type and concentration of the gases and vapors being sampled and results from the UV light interacting with them.

Hot gases and vapors may contribute to a decrease in sensitivity because they may condense on the lamp window. Condensation may eventually evaporate off the window, but it will usually leave a residue that must be removed by cleaning the lamp window.

Since some UV inhibiting deposits are invisible to the eye, regular cleaning of the lamp window is strongly recommended. Clean the lamp frequently to prevent a heavy buildup of deposits that may be difﬁcult to remove.

WARNING: Do not remove the UV lamp in a hazardous location.

The UV lamp cleaning kit (Part No. 83 18 318) includes aluminum oxide powder (3.0-micron powder) and cotton swabs. Additionally, you will require approximately 10 mL of methanol. When ordering methanol, specify purge and trap grade. The instructions provided below are for 10.6 eV lamps. Refer to Cleaning the Lithium Fluoride Window for special instructions to clean the 11.7 eV lamp window.

WARNING: Never touch the UV lamp window with your ﬁngers.

To clean the UV lamp:

1. Remove the lamp as outlined in Removing and Replacing the UV Lamp on page 80.

2. Allow the lamp to cool to room temperature to avoid thermal shock, which could crack the window.

3. Dampen a cotton swab in methanol and dab it into the cleaning compound. Allow a small amount of the cleaning compound to adhere to the cotton tip.

WARNING: Do not use methanol to clean the 11.7 eV lamp window.

4. Using small circular motions, rub the cleaning compound onto the lamp window. Do not exert excessive force onto the window, since the window can be permanently damaged by misuse.

5. Continue cleaning for approximately one minute.

6. Dampen a new cotton swab with methanol and remove any trace amounts of the cleaning compound from the lamp window.

7. Wipe the window and the lamp with a dry, lint free tissue to remove any trace amounts of the cleaning compound and methanol. All traces of cleaning compound must be removed.

8. If you removed an O-ring from the lamp, replace it now. Ensure your hands are clean and dry.

9. Without touching the lamp window, replace the lamp as outlined in Removing and Replacing the UV Lamp on page 80.

Routine Maintenance

Cleaning the Lithium Fluoride Window

To clean the 11.7 eV lamp window:

1. Clean the lamp window with dry aluminum oxide powder on a dry cotton swab. Do not use methanol or water.

2. Wipe the window and the lamp with a dry, lint free tissue to remove any trace amounts of the cleaning compound and methanol. All traces of cleaning compound must be removed.

3. The lamp window can also be regenerated by storing the lamp in a desiccant for at least 5 days.

NOTE: You may not be able to fully clean the 11.7 eV lamp window.

Routine Maintenance

Replacing the Sample Inlet Filter

The Multi-PID 2 is equipped with a combined dust and water ﬁlter to reduce detector contamination. As the ﬁlter collects dust, the MultiPID 2’s inlet ﬂow rate and sensitivity decrease. The ﬁlter will not allow water to pass through, but the ﬁlter will not stop all solvents.

NOTE: Do not aspirate liquid samples with the Multi-PID 2!

Replace the ﬁlter on a weekly basis, or more frequently if the MultiPID 2 is used in a dusty or wet environment. You must replace the ﬁlter if the Multi-PID 2 has been exposed to water. If you are sampling hot gases or vapors, condensation in the sample line may also affect the ﬁlter.

WARNING: Do not replace the inlet ﬁlter in a hazardous location.

To replace the inlet ﬁlter:

1. Turn the instrument off. Unscrew the filter housing from the detector housing. Be careful not to lose the O-ring seal.

2. Remove the Teflon/Polypropylene filter and install the new filter (Part No. 83 17 681). Place the filter so that the Teflon side is facing down in the filter housing and the mesh side is facing the Multi-PID 2. Handle the filter disk only by the edges. The mesh may be damaged or contaminated by excessive handling. Use forceps if possible.

3. Replace the filter housing.

4. Recalibrate and then continue normal operation.

Installing Alternate AC Plug on the Battery Charger

In most cases the Multi-PID 2 will be shipped with an AC line cord that will ﬁt the AC wall outlet in your area. If this cannot be done, you may need to obtain an AC line cord suitable for the AC receptacle in your area. The AC line cord, attached plug and receptacle must be marked with your country’s certiﬁcation mark and the cord must have a Harmonization (HAR) mark. The line cord must be rated for either 100 to 120 VAC at 60 Hz or 220 to 240 VAC at 50 Hz. The voltage rating will depend on the voltage in your area.

Contact your Dräger Safety representative to obtain more information.

Calibration Gas Supplier

The recommended span gas is isobutylene in air. 100 ppm isobutylene in air may be obtained from Dräger Safety.

The exact concentration will be determined by your application. Other concentrations and other gases may be obtained from your local gas supplier. If you cannot locate a local gas supplier, contact Dräger Safety’s Technical Support Department.

Presets and Response Factors

Presets simplify Memory Slot programming, and provide standard response factors and alarm levels for approximately 100 compounds. The name, response factor and three alarm levels are all set from the preset.

You can change any of the values entered in the Memory Slots. Changes made to the library information that has been loaded into a Preset will have no effect on the original library entry.

The response factors were determined over the range 5 - 500 ppm, based on a 100-ppm isobutylene calibration. Isobutylene RF = 1.0. The following formula is used for calculation of response factors:

Appendices

Response Factor =

Actual Concentration

Multi-PID 2 Response

A response factor less than 1.0 indicates a compound response better than that of isobutylene. A response factor greater than 1.0 indicates a lower response than that of isobutylene.

NOTE: It does not matter which response factor is entered. The MultiPID 2’s response is not speciﬁc to any one compound. The displayed reading represents the total concentration of all ionizable compounds in the sample.
