  • Page 3: Description

    D e t e c t i o n D e t e c t i o n Description The POLI multi-gas detectors (MP400 & MP400P) offer 4- or 5-gas monitoring of oxygen (O combustible (LEL) gases, toxic gases, carbon dioxide (CO ), and volatile organic compounds (VOCs).

  • Page 4: Caution

    Special Conditions for Safe Use • The POLI multi-gas detector must be calibrated if it does not pass a bump test, when a new sensor has been installed, or at least once every 180 days, depending on use and sensor exposure to poisons and contaminants •...

  • Page 5: Proper Product Disposal At The End Of Life

    1. Battery Fully charge the POLI battery upon receiving the instrument and before each day’s use. The Li-ion battery is preferably charged by the WatchGas USB Charger. NOTE: Any USB A to Micro B USB cable works for (partial) charging, but does not work for communication with WatchGas Suite confi guration and data transfer software.

  • Page 6: Battery Replacement

    NOTE: For best preformance it’s strongly recommended to fully charge the POLI before each use. 1.3 BATTERY REPLACEMENT The POLI Lithium-ion battery pack is free of maintenance. In case of a battery failure or end of operating life, please contact the WatchGas Service Department or an authorized service center for a battery replacement.

    This feature can also be initiated manually by initiating a Panic Alarm if the worker fi nds themself in distress. In addition, the POLI alarms when the battery voltage is low, pump is blocked, and in other fault conditions.

  • Page 9: Active Sensor Displays

    3.3 ACTIVE SENSOR DISPLAYS The POLI is a fl exible platform with four sensor sockets that allows use of anywhere between one and fi ve sensors, the latter with a dual toxic sensor. When one or more sensors is either not installed or...

    The Peak, Minimum, STEL and TWA for each sensor since turn- on are displayed, with the option to clear and re-start Peak or Minimum. In addition, If the POLI is fi tted with a PID or Pellistor LEL sensor, the corresponding Calibration Gas and Measurement Gas (and its Correction Factor) are displayed (after Battery information).

  • Page 11: Configuration Mode

    (see Section 5). 4. Confi guration Mode The Confi guration Mode (Confi g Mode) is used to adjust the POLI’s operation settings and calibrate sensors. Remember that the two text/symbol boxes at the bottom of the display are mapped to the Left [+/OK] and Right [ / ] keys and will vary with the menu.

  • Page 14: Calibration And Bump Testing

    The POLI should be calibrated on the fi rst day of use and at regular intervals not to exceed 180 days, depending on use and exposure to particulates, contaminants and sensor poisons. A daily bump test should be performed to ensure a functional response of all sensors and alarms.
  • Page 15 * The calibration frequency must be defi ned by the user’ s company policy because each application is diff erent and may cause a sensor’ s sensitivity loss for various reasons out of WatchGas’ s control, such as liquids, dirt or corrosion preventing gas from reaching a sensor, or exposure to chemicals that poison a sensor’...
  • Page 16 Because PIDs and LEL sensors are broadband detectors, they can be calibrated with many possible gases. The type of calibration gas is selected from a list of several hundred compounds in WatchGas Suite (Section 5.1), typically 100 ppm isobutylene for PID and 50 %LEL (2.2 vol%) for methane.
  • Page 17 (Internal channels distribute the gas to each sensor, even though during measurements the gas enters and leaves through the four fi lters on the face of the POLI.) The gas fl ow should be low, between 0.2 and 0.3 LPM to avoid pressure build-up in the sensor channels. Do not use a T-connector or demand-fl ow regulator with diff usion sampling.
  • Page 18 ’ . Verify that the span gas concentrations match those of the gas cylinder. If not, abort and go to the Span Value menu to adjust. If OK, turn on the gas fl ow, connect the gas to the POLI, and press Start to initiate the 60-second count-down.
  • Page 19 User Manual Multi-Gas detector POLI D e t e c t i o n D e t e c t i o n WARNING Do not replace sensors in hazardous locations! Gases that are not available as mixtures must calibrated individually by de-selecting all other sensors.

    User Manual Multi-Gas detector POLI D e t e c t i o n D e t e c t i o n CAUTION Be sure that the Gas Concentration Unit of the instrument matches that on the Calibration Gas cylinder used for each sensor. Otherwise, dangerously low readings could result. Once calibration is complete, the units can be changed between the fi rst four on the list above and the readings will be correct.
  • Page 22 The alarm stays off as long as the instrument is held in a horizontal position, such as laying face up on a table, and triggers when in any other position. A pre- warn can be cleared by quickly returning the POLI to a horizontal position, or pressing the Left [+/OK] key.

  • Page 23: Datalog

    All data are retained (even after the unit is turned off ) in non-volatile memory so that they can be downloaded at a later time to a PC using WatchGas Suite software (see Section 6). Datalogging cannot be turned off . When datalogging is full, it begins to overwrite the oldest data, which are permanently lost.

  • Page 24: Monitor Set-Up

    4.8.2 PUMP SPEED If the POLI is equipped with a pump, it can be set to low or high fl ow, or turned off to save battery and sample by diff usion. Low fl ow typically runs between 140 and 210 cc/min while high fl ow runs between 350 - 450 cc/min, both with a 0.45 μm fi lter in place.
  • Page 25 The backlight turns off automatically after 10 seconds if no key is pressed. 4.8.7 LCD AUTO FLIP The LCD can be confi gured to fl ip automatically when the POLI is positioned upside-down. The auto- fl ip feature can be turned off .

    MP400 or MP400P models. An MP400H can communicate with 7 MP400S units up to 0.5 miles (0.8 km) away, forming an WatchGas Squad of up to 8. Multiple (up to 8) WatchGas Squad can be connected to form an WatchGas Platoon using the WatchGas link modem, which communicates up to 2 miles (3 km) with each MP400H.

  • Page 27: Data Communication

    The operating channel can be selected between 904.5 MHz, 915 MHz and 927 MHz. 5. Data Communication The WatchGas Suite software can be used to 1) download logged data, 2) upload configuration parameters to the instrument, 3) display readings on a PC and download in real time and 4) upgrade the instrument firmware.

  • Page 31: Maintanance

    IMPORTANT A pumped POLI should not be calibrated or operated without a fi lter. Operation without a fi lter may damage the instrument. The only exception to this requirement is for use with reactive gases that may be partially lost on the fi lter.

  • Page 32: Removing / Cleaning / Replacing Sensor Modules

    All sensors are located inside the sensor compartment on the top side of the POLI circuit board assembly. They are accessed by removing the six screws in the back of the POLI and then turning the instrument over and lifting off the sensor cover.
