4.3 Testing Alarm Indicators

Under normal-operation mode and non-alarm conditions, the buzzer, vibration alarm,

LED, and backlight can be tested at any time by pressing [+/OK] once.

IMPORTANT!

If any of the alarms do not respond to this test, check the Alarm Settings in Programming

Mode. It is possible that any or all of the alarms have been turned off. If all of the alarms

are turned on, but one or more of them (buzzer, LED lights, or vibration alarm) does not

respond to this test, do not use the instrument. Contact your mPower distributor for

technical support.

4.4 Pump Status

IMPORTANT!

During operation, make sure the probe inlet and the gas outlet are free of obstructions.

Obstructions can cause premature wear on the pump, false readings, or pump stalling.

During normal operation, the pump icon alternately shows inflow and outflow as shown

here:

If there is a pump failure or obstruction that disrupts the pump, the alarm sounds and you

see this icon blinking on and off:

Once the obstruction is removed, you can restart the pump by pressing the [+/OK] key. If

the pump does not restart, and the pump stall alarm continues, consult the

Troubleshooting section of this guide or contact your mPower distributor for technical

support.

Note: Pump status is not indicated on the diffusion POLI.

4.5 Calibration Status

If one or more sensors requires calibration, then the screen shows a highlighted 'CAL'.
