  • Page 3 POLI User’s Guide Read Before Operating This manual must be carefully read by all individuals who have or will have the responsibility of using, maintaining or servicing this product. The product will perform as designed only if it is used, maintained and serviced in accordance with the manufacturer’s instructions. The user should understand how to set the correct parameters and interpret the obtained results.
  • Page 4 POLI User’s Guide 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: General Information

    POLI User’s Guide General Information 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). The MP400 is a diffusion sampling model with standard O , LEL, carbon monoxide (CO) and hydrogen sulfide (H S) configuration.

  • Page 6: Battery

    POLI User’s Guide Battery Fully charge the POLI battery upon receiving the instrument and before each day’s use. Li-ion battery is charged using a Micro-USB cable. NOTE: Any locally-obtained USB A to Micro B USB cable works for charging, but does not work for communication with mPower Suite configuration and data transfer software.

  • Page 7: User Interface

    POLI User’s Guide User Interface The POLI user interface consists of two keys, four sensor sockets, one large Liquid Crystal Display (LCD), eight alarm LEDs, one buzzer, and two vibration alarms. (pump models) (Gas inlet/outlet diffusion models) 3.1 Displays and Keys The LCD provides visual information that includes real-time gas readings, sensor types, datalog / battery / pump / wireless status, and others.

  • Page 10: Active Sensor Displays

    POLI User’s Guide 4.3 Active Sensor Displays The POLI is a flexible platform with four sensor sockets that allows use of anywhere between one and five sensors, the latter with a dual toxic sensor. When one or more sensors is either not installed or turned off, the display only shows the installed, active sensors: 4.4 Pump Status During normal operation, the pump icon alternately shows inflow and outflow.

  • Page 11: Alarm Testing

    POLI User’s Guide 4.5 Alarm Testing Under normal operation mode and non-alarm conditions, the audible (buzzer) alarm, vibration alarm, LED, and backlight can be tested at any time by pressing [+/OK] once. WARNING! If any of the alarms do not respond to this test, check the Alarm Settings in Configuration Mode to see if the alarms have been turned off.

  • Page 12: Configuration Mode

    POLI User’s Guide Configuration Mode The Configuration Mode (Config 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. 5.1 Entering Configuration Mode Press and hold both the [+/OK] and [ /↓] keys simultaneously for 3 seconds until the password screen appears.

  • Page 14 POLI User’s Guide 5.3.2 Navigating Lists There are two types of menus in Configuration Mode: 1) those that ask for selection from a list and 2) those that ask for a numerical value to be entered. Simple lists and those with radio buttons are used when only one option can be selected.
  • Page 15 POLI User’s Guide 5.3.2.3 Radio Button Lists Radio buttons are used when only a single item in the list can be selected, and there are no blue further sub-menus. When a radio button list appears, follow the numbered sequence in shown below.

  • Page 16: Calibration And Bump Testing

    POLI User’s Guide 5.4 Calibration and Bump Testing Use this menu to perform zero or span calibration for one or more sensors, bump test the sensors and alarms for function, and change the span gas concentration. The POLI should be calibrated on the first day of use and at regular intervals not to exceed 180 days, depending on use and exposure to particulates, contaminants and sensor poisons.
  • Page 17 POLI User’s Guide 5.4.1 Calibration Set-Up 5.4.1.1 Span Gas Selection The gas concentration chosen for span calibration and bump testing should be near the middle to upper range of the concentrations expected to be measured. If the possible gas concentrations are unknown, choose a gas concentration near the upper end of the sensor’s range, or near the highest exposure limit (e.g., TWA, STEL or Ceiling) of concern.

Diffusion instruments have a black cap covering the Luer connector to protect the unit from dirt and moisture. This cap must be removed to attach the Luer fitting and connected tubing leading to the gas supply.
  • Page 19 POLI User’s Guide 5.4.2 Fresh Air (Zero) Calibration Zero calibration should precede span calibration and be done in clean air with 20.9% oxygen. This procedure determines the zero points of most sensors and the span calibration for the oxygen sensor. No gas connections are required if the ambient air contains no detectable contaminants.

    POLI User’s Guide connect the gas to the POLI, and press Start to initiate the 60-second count-down. The When complete, the display shows the sensor readings alternately with a ‘Pass’ or ‘Fail’ message. The span calibration can be aborted at any time during the count-down by pressing [ /↓] (Abort). NOTE: If the sensor calibration fails, try again.

    POLI User’s Guide 5.6.4.2 Man-Down Warn Time This menu allows adjustment of the time allowed for the user to clear a pre-warn signal before the unit goes into full Man-Down Alarm. The pre-warn time can be adjusted between 10 and 60 seconds and the default value is 30 seconds.
  • Page 24 POLI User’s Guide 5.8.2 Pump Speed If the POLI is equipped with a pump, it can be set to low or high flow, or turned off to save battery and sample by diffusion. Low flow typically runs between 250 and 350 cc/min while high flow runs between 350 and 450 cc/min, both with a 0.45 µm filter in place.
