6.3 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 [Y/+] once.
IMPORTANT!
If any of the alarms does 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 RAE Systems distributor for technical support.
6.4 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 try to restart the pump by pressing the [Y/+]. If the pump does
not restart, and the pump stall alarm continues, consult the Troubleshooting section of this guide or
contact RAE Systems Technical Support.
It is advisable to perform a pump stall test periodically, to make sure the pump is working properly and
there are no leaks in the system. To perform a pump stall test, simply block the gas inlet with your finger.
To pass the test, the instrument should go into a pump alarm. Press [Y/+] to disable the alarm and return
to normal operation.
Note:
Pump Status is not indicated on diffusion MultiRAEs.
6.5 Calibration Status
The instrument displays this icon next to the sensor that requires calibration:
Calibration is required (and indicated by this icon) if:
The lamp type has been changed (for example, from 10.6 eV to 9.8 eV).
The sensor module has been replaced with one whose calibration is overdue.
The defined period of time between calibrations has been exceeded.
If you have changed the calibration gas type without recalibrating the instrument.
The sensor has failed a previous calibration.
