1. Description
The MultiPro is a multi-sensor gas detector that can be configured to meet a wide variety of user requirements. This chapter provides an overview of many of the features of the MultiPro. More detailed descriptions of the specific features of the MultiPro are contained in the subsequent chapters of this manual.
1.1 Methods of sampling
The MultiPro may be used in either diffusion or sample­draw mode. In either mode, the gas sample must reach the sensors for the instrument to register a gas reading. The sensors are located at the bottom of the instrument. There are three distinct sensor ports that allow the sample to reach the individual sensors.
The sensor ports must be
kept free of obstruction. Blocked sensor ports can lead to inaccurate and potentially dangerous readings.
In diffusion mode, the atmosphere being measured reaches the sensors by diffusing through the vents at the bottom of the instrument. Normal air movements are enough to carry the sample to the sensors. The sensors react quickly to changes in the concentrations of the gases being measured. Diffusion-style operation monitors only the atmosphere that immediately surrounds the detector.
The MultiPro can also be used to sample remote locations with the hand-aspirated sample-draw kit or with the motorized, continuous sample draw pump (both available separately). During remote sampling, the gas sample is drawn into the sensor compartment through the probe assembly and a length of tubing. Remote sampling operations only monitor the atmosphere at the end of the sample draw probe.
Use of the hand-aspirated sample draw kits is covered in section 3.1.
Use of the motorized sample draw pump is covered in section 3.2.
A detailed description of the MultiPro probe assembly is given in section 5.7.
1.2 Multi-sensor capability
The MultiPro can be configured to simultaneously monitor oxygen, carbon monoxide, hydrogen sulfide and combustible gases and vapors. All sensors are replaceable in the field. Each of the MultiPro’s sensor channels is configured for a specific type of sensor.
Note: It is necessary to verify the accuracy of the MultiPro by calibration with known concentration test gas whenever a change is made to the sensors installed in the instrument.
Calibration procedures are discussed in detail in Chapter 4.
The MultiPro uses electrochemical toxic gas sensors that have been designed to minimize the effects of common interfering gases. These sensors provide accurate, dependable readings for toxic gases commonly encountered during confined space entry and other industrial applications.
Different measurement units are used depending on the gas being measured.
Type of Hazard Measurement unit
Oxygen (O2) Percentage by
volume
Combustible gas Percentage of lower
explosive limit (%LEL)
Carbon Monoxide, Hydrogen Sulfide
Table 1.2. Units of Measurement.
Parts per million (PPM)
1.3 Calibration
The MultiPro detector features one-button fresh air and span calibration.
The accuracy of the MultiPro should be checked periodically with known concentration calibration gas. Failure to check accuracy can lead to inaccurate and potentially dangerous readings. (The Canadian Standards Association (CSA) requires an accuracy check using known concentration calibration gas prior to each day’s use.)
Calibration procedures are discussed in detail in Chapter 4.
Recommended calibration frequency is discussed in Appendix B.

1.4 Alarm logic
MultiPro gas alarms can be adjusted with BioTrak Software through a PC with an IrDA port or directly with the MODE button (see Chapter 6 for direct programming instructions). Alarms may be set anywhere within the nominal range of the specific sensor type. When an alarm set point is exceeded a loud audible alarm sounds, and the bright red LED alarm lights flash.
1.4.1 Atmospheric hazard alarms
The combustible gas alarm is activated when the percent LEL (Lower Explosive Limit) gas concentration exceeds any pre-set alarm level.
Two oxygen alarm set points have been provided; a danger alarm for low concentrations associated with oxygen deficiency and a warning alarm for high concentrations associated with oxygen enrichment.
Four alarm set points have been provided for each toxic gas sensor: Warning, Danger, STEL (Short Term Exposure Limit) and TWA (Time Weighted Average).

may indicate a hazardous combustible gas concentration that exceeds the MultiPro’s zero to 100 percent LEL detection range.
1.4.2 Low battery alarms
The MultiPro may be equipped with either a rechargeable Lithium Ion (Li-Ion) or an alkaline battery pack. The MultiPro includes multi-staged low battery alarms to let the user know that the battery is running low.
For detailed information concerning the low battery alarms, see section 2.4.5.
Use only Duracell MN1500 or Ultra MX1500, Eveready Energizer E91­LR6, Eveready EN91 batteries. Substitution of batteries may impair intrinsic safety.
1.4.3 Sensor over range alarms.
The MultiPro will go into alarm if a sensor is exposed to a concentration of gas that exceeds its established range. In the case of an LEL reading that exceeds 100% LEL, the LEL channel will be automatically disabled by the instrument and the instrument will remain in constant alarm until it is turned off, brought to an area that is known to be safe, and then turned back on. The display will show “OL” in place of the sensor reading for any channel that has gone into over range alarm.
See section 2.4.5 for further details on sensor over range alarms.
A sensor range chart is provided in Appendix C.
In the event of an LEL overrange alarm the MultiPro must be turned off, brought to an area that is known to be safe and then turned on again to reset the alarm.
1.4.4 LEL response failure due to lack of
alarm
O
2
The MultiPro features automatic warning against LEL sensor response failure due to lack of oxygen. See section 2.4.7 for details.
1.4.5 Security beep/flash
The MultiPro includes a security beep function that is designed to notify the user that the instrument is powered up and running. Once enabled the MultiPro will emit a short audible beep and give a short flash on the LED at a user-defined interval. The security beep/flash function may be enabled and the interval may be changed with BioTrak software or directly with the MODE button (see Chapter 6 for direct programming instructions).
7
1.4.6 Latching peak alarms
The MultiPro’s alarms are self-resetting unless the alarm latch is enabled. With the MultiPro’s alarm latch enabled, the audible and visible alarms will continue to sound after the atmospheric hazard has cleared. Press the MODE button to reset the alarms. If the alarm latch is disabled and the alarm condition is no longer present, the instrument will automatically return to normal operation, and the visible and audible alarms cease without further input from the user.
1.4.7 Fault detection
MultiPro software includes a number of additional alarms designed to ensure the proper operation of the instrument. When the MultiPro detects that an electronic fault or failure condition has occurred, the proper audible and visible alarms are activated and an explanatory message or message code is displayed.
The MultiPro is designed
to detect potentially life threatening atmospheric conditions. Any alarm condition should be taken seriously. The safest course of action is to immediately leave the affected area, and return only after further testing determines that the area is once again safe for entry.
1.5 Other electronic safeguards
Each time the detector is turned on, the MultiPro automatically tests the LED alarm light, audible alarm, internal memory and pump status (if so equipped). The battery is monitored continuously for proper voltage. The MultiPro also monitors the connection of sensors that are currently installed. The detection of any electronic faults causes the activation of the audible and visible alarms and causes the display of the appropriate explanatory message.
1.5.1 Heartbeat
At the center of the display is a heart symbol that will blink every few seconds to show that the instrument is functioning normally.
Instructions are included with the replacement sensor.
Replacement sensor part numbers and sensor ranges are given in Appendix B.
Sensor cross-sensitivity figures are given in Appendix C.
A sensor that cannot be calibrated or is found to be out of tolerance must be replaced immediately. An instrument that fails calibration may not be used until testing with known concentration test gas determines that accuracy has been restored, and the instrument is once again fit for use.
Calibration procedures are discussed in detail in Chapter 4.
1.7 Optional sample draw pump
A motorized sample-draw pump is available for the MultiPro for situations requiring continuous "hands free" remote monitoring.
Use only part number 54­49-102 sample draw pump with the UL/CSA-approved version of the MultiPro. Use only part number 54-49-102-5 sample draw pump with the ATEX-approved version of the MultiPro.
The pump contains a pressure sensor that detects restrictions in airflow caused by water or other obstructions being drawn into the unit and immediately acts to turn the pump off in order to protect the sensors, pump, and other MultiPro components from damage.
Pump status is continuously monitored by the MultiPro microprocessor. When the pump is active and functioning properly, “PUMP” is displayed near the center of the display. Low flow or other pump fault conditions activate audible and visible alarms and cause the display of the appropriate explanatory message.
1.6 Sensors
The MultiPro can be configured to simultaneously monitor oxygen, carbon monoxide, hydrogen sulfide and combustible gases and vapors. The sensor configuration of the MultiPro may be specified at the time of purchase, or changed in the field by appropriately trained personnel.
Note: A CF Value may be required when replacing the 54-49-24 CO/H2S sensor.
1.7.1 Special precautions when using the
MultiPro pump
The rubber material used in the MultiPro diaphragm pump is susceptible to temporary compromise by exposure to high levels of flammable fuel and solvent vapors. If the MultiPro is being used to sample atmospheres that exceed 50% LEL, test the pump frequently to ensure that pump function has not been compromised.
8
To test the pump, block the end of the sampling line (probe) inlet with a finger. The pump should quickly go into alarm, which indicates proper function. If the pump fails to go into alarm while the inlet is blocked, it is not working properly; and the MultiPro may not be providing an accurate reading. If the pump test fails, the safest course of action is to immediately leave the affected area and to return only after further testing with known, functional detection equipment confirms that the area is once again safe for entry.
Do no use the pump to sample for prolonged periods in conditions where the concentration of solvent or fuel vapors may be greater than 50% LEL.
1.8 Data storage
The MultiPro includes a black box data recorder and an event logger as standard features.
1.8.1 Black box data recorder
A black box data recorder is a standard feature in the MultiPro. The “black box” is continually in operation whether the user is aware of it or not. The black box stores important information such as gas readings, turn-on times, turn-off times, temperatures, battery conditions, the most recent calibration date and settings, types of sensors currently installed, sensor serial numbers, warranty expiration and service due dates, and current alarm settings.
There is a finite amount of memory storage available in the black box data recorder. Once the memory is “full”, the MultiPro will begin to write the new data over the oldest data. The black box data recorder will store approximately 41 hours of data in one-minute increments before it begins to write new data over the oldest data. In this way, the newest data is always conserved.
To extract the information from the black box data recorder, the MultiPro must be returned to Sperian Instrumentation. Once the data is downloaded from the instrument, a report will be generated. The instrument and the report will then be returned to the user. Simply call Sperian’s Instrument Service Department to obtain a return authorization number. There is no charge for the downloading service, but the user is responsible for any freight charges incurred.
The “black box” data recorder in the MultiPro can be upgraded to a fully enabled datalogger at any time. All that is required is the activation code that corresponds to the serial number of the MultiPro.
1.8.2 Event logger
The event logger in the MultiPro stores data associated with alarm conditions. Each (alarm) event includes the following data for each of the installed sensors: Sensor type, Max reading, average reading, start time, end time and duration of the event. The MultiPro stores the 20 most recent events. Once 20 events have been stored, the MultiPro will begin to systematically overwrite the data from the oldest event in memory with data from new events. One event may be a combination of different alarms occurring simultaneously or in immediate succession. The event logger may be downloaded using Sperian Instrumentation’s' BioTrak software. The PC must be equipped with IrDA to provide a connection.
1.9 MultiPro design components
1. Case: The instrument is enclosed in a
solid PC (polycarbonate) case with TPE (rubber) overmold.
2. Front face: The front face of the instrument houses the MODE button, LCD (liquid crystal display), LED alarm light, IrDA port and audible alarm.
3. Display: A liquid crystal display (LCD) shows readings, messages, and other information.
4. Alarm light: A top and front-mounted LED (light emitting diode) alarm lights provides a visual indication of alarm state. The light emits a bright red light when the instrument is in alarm.
5. Infrared Port: The infrared port is located next to the MODE button on the front face of the instrument. The infrared port is used for communications between the MultiPro and a PC.
6. On / Off "MODE" button: The large black push-button on the front of the instrument is called the "MODE" button. The MODE button is used to turn the MultiPro on and off as well as to control most other operations, including the automatic calibration adjustment.
7. Sensor compartment cover: The sensors are located in a vented compartment at the bottom of the instrument.
8. Audible alarm port: A cylindrical port extending through the front of the instrument just above the display houses the loud audible alarm. The waterproof audible alarm seats directly to the rubber inner-liner to protect the instrument against leakage or exposure to liquids.
9. Battery pack: Two types of interchangeable battery packs
