English is the default language, and Chinese can be selected by users. 5.2.5.6 Backlight Mode The LCD backlight can be set to illuminate either automatically, based on ambient light conditions, or manually. It can be shut off too. 5.2.5.7 Auto Flip LCD The LCD can be configured to auto flip automatically when the POLI is positioned upside-down. The auto flip feature can be set off. 5.2.5.8 Man Down Alarm Users can enable or disable the Man Down Alarm function according to their jobs. 21 POLI Users Guide The POLI offers Man Down Alarm as a critical and potentially lifesaving safety feature for all models. When the instrument carried by a user stops moving, the Man Down Alarm is triggered and the user may be unable to walk or put the POLI away. MP400S transmits various alarms including Man Down to team-mates, supervisors or safety officers on site or nearby via a wireless network for a timely rescue to save lives. Note: Remote notification requires wireless connection to a network. The Man Down icon shown on the main screen means the Man Down function is active. When the Man Down function is active, the POLI senses any motionless in the certain duration of the Motionless Time parameter. If the instrument is not moved during that time, then a pre-alarm is activated to alert the user, and shows the OK? screen. Pressing

[+/OK] clears the alarm and returns the POLI to its normal operation. Pressing [

/] sets it into Man Down Alarm. MP400S wirelessly transmits the Man Down message in real time to remote observers. If neither key is pressed, then after the countdown, it goes into Man Down Alarm and also sends a message to remote observers if wirelessly enabled. 5.2.5.9 Man Down Alarm Timeout Man Down alarm timeout is at default 30 seconds and can be changed between 10 and 60 seconds. 5.2.5.10 Man Down Sensitivity Motion sensitivity can be set to low, medium and high in accordance with levels of user's motion. 1.

Calibration and Test 6.1 Manual Alarm 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 [+/OK]. If any alarm does not respond, check the alarm settings to make sure all alarms are enabled

(LED, Buzzer, Vibrator under Config mode/Alarm/Alarm Device should be all Enabled). If any alarms are enabled but not functional, the instrument should not be used. Contact mPowers technical support. 6.2 Bump Testing and Calibration mPower recommends that a bump test be conducted periodically on the POLI. The purpose of a bump test is to ensure that the instruments sensors respond to gas and all the alarms are enabled and functional. The POLI multi-gas detector must be calibrated if it does not pass a bump test, or at least once every 180 days, depending on use and sensor exposure to poisons and contaminants. Calibration intervals and bump test procedures may vary due to national and local legislations or regulations. A bump test can be performed manually. When a bump test 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. 6.2.1 Bump (Functional) Testing The same gas is used for a bump test as for calibration. A constant-flow regulator producing 0.5 to 1.0 liters per minute should be used. Pumped models require a T calibration tube, as illustrated below. 24 POLI Users Guide Note: Make sure pressure in the calibration gas cylinder is higher than 100 psi when using a T calibration tube (pumped models only). 1. Turn on your POLI by pressing and holding the [

/] key, 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 instruments 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 yet warmed up, you see three dashes (--) next to it. 2. Install a calibration adapter on the gas inlet at the top of the diffusion version POLI. 3. Connect the pump version instrument to the T calibration tube and connect it to the calibration gas. 4. Turn on the standard gas to initiate flow. 5. Press [+/OK] key to start the bump test, or press [

/] to quit. 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. Important! If one or more sensors fail a bump test, be sure to calibrate those sensors. 6. The bump test is now complete. Press [+/OK] to exit and return to the calibration menu. If all of alarms and sensors have passed and no sensor is due for a calibration, the instrument is now ready for use. 6.2.2 Air (Zero) Calibration This operation sets the zero point of the sensor calibration curve for clean air. It should be performed before other calibrations. Note: If you use a zero air cylinder, you must use the Calibration Adapter (and a T calibration tube if the instrument has a pump). Using a calibration adapter is not necessary for calibration in fresh air. 25 POLI Users Guide This procedure determines the zero point of the sensor calibration curve for all the sensors that require a zero calibration. The POLI should be zero calibrated in clean ambient air with 20.9% oxygen or with a cylinder of clean zero air. At the calibration menu, select Fresh Air by pressing [+/OK] 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 [

6.2.3 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. 6.2.3.1 POLI Pump Version The POLI pump draws at a flow rate of between 200cc/min and 450cc/min. The instrument must be connected to a cylinder of calibration gas with supplied tubing featuring a T calibration tube, as illustrated below. Note: A constant-flow regulator with flow rates from 500cc/min to 1000cc/min should be used Note: Make sure pressure in the calibration gas cylinder is higher than 100 psi when using a T calibration tube. (Pump version only) 6.2.3.2 POLI Diffusion The water-trap filter or inlet cover needs to be taken down first if it is a diffusion version. A calibration adaptor with a 15cm hose is used for supplying calibration gas to the inlet at the top of the instrument. 26 POLI Users Guide 1. Connect gas inlet of the diffusion version POLI to the calibration adaptor and connect it to its gas source. 2. Turn the adaptor clockwise to secure the adaptor to the instrument. 3. Make sure the calibration adapter is securely attached before starting the flow of calibration gas. 6.2.4 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 POLI. 1. Start the flow of calibration gas. 2. Attach the calibration adapter and gas to the POLI 3. Press [+/OK] to begin calibration. A countdown screen is shown. You can abort the calibration at any time during the countdown by pressing [

/]. 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. 6.2.5 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. Start the flow of calibration gas. 4. Connect the calibration adapter and connect it to a source of calibration gas. 5. Verify that the displayed calibration value meets the concentration label on the gas cylinder. 6. Press [+/OK] to start calibrating. You can abort the calibration at any time during the countdown by pressing [

/]. 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 again, turn off the power and then replace the sensor. WARNING: Do not replace sensors in hazardous locations!

Use the included Micro-USB (5-pin)-to-USB cable to connect the computer running mPower Suite. You may download the latest version of application software at www.mpowerinc.com . Micro B (5-Pin) to USB cable 28 POLI Users Guide 8. Maintenance The POLI requires little maintenance, aside from replacing sensors, filters, batteries and pumps if the instrument is equipped. 8.1 Replacing Filters Pump Version If the external filter is dirty or clogged, remove it by unscrewing it from the inlet. Discard it and replace it with a new water-trap filter. IMPORTANT! A pumped POLI must not be calibrated or operated without a filter. Operation without a filter may damage the instrument. 8.2 Removing/Cleaning/Replacing Sensor Modules WARNING! Do not replace sensors in hazardous locations. All sensors are located inside the sensor compartment in the upper half portion of the POLI PCB 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. 1. Turn off the instrument. 2. Loose and remove the six screws in the back of the instrument. 3. Turn the instrument over, lift off the front cover from the back of the instrument. 4. Carefully lift out each sensor you wish to inspect or replace. 5. Install the replacement sensor. Make sure the electrical contact pins are aligned with the holes in the PC board and that the sensor is seated firmly. 6. Replace the cover and tighten the 6 screws. 29 POLI Users Guide IMPORTANT! Always perform a full calibration after replacing sensors. 8.3 Replacing Pumps If your POLI has a pump and it requires replacement, please contact mPower service department. 30 POLI Users Guide 9. Alarm Overview The POLI provides an unmistakable five-way alarm notification that combines local alarms on the device with real-time remote wireless alarm notification to enhance worker safety up to the next level. Local alarms include audible buzzer alarm, visible alarm via bright LED lights, vibration alarm, and an alarm notification on the display. These can be programmed or selectively turned on or off. 9.1 Alarm Signals During each measurement period, the gas concentration is compared with the programmed alarm limits for Low, High, TWA and STEL alarms. If the concentration exceeds any of the preset limits, the alarms are activated immediately to warn both the POLI user and a remote safety officer (if wireless is enabled) of the alarm condition. In addition, the POLI alarms when the battery voltage is low, pump is blocked, etc. When a low-battery alarm occurs, there may be approximately 10 minutes of operating time remaining. However, it is recommended that you promptly change using a fully charged POLI or charge the battery in a non-hazardous location. 9.2 Testing Alarms Under normal operation mode and non-alarm conditions, the audible, visual, and vibration alarms can be tested at any time by pressing the [OK] key. 31 POLI Users Guide 10.
