11.3 Testing Alarm Indicators

Under normal-operation mode and non-alarm conditions, the buzzer, LEDs, and backlight can be tested at
any time by pressing [Y/+] once.
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 or LED lights) does not respond to this test, do not use the instrument. Contact your
RAE Systems distributor for technical support.

11.4 Pump Status

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: For all AreaRAE Plus/Pro instruments with a 4R+ PID, if the pump is in alarm for more than five
minutes, the PID lamp automatically turns off. The display reading shows "- - -" and there is a "Lamp"
alarm. Click [Y/+] to restart the pump. If there is no longer a pump alarm, then the PID lamp will require
a 2-minute warm-up to stabilize. During this time, the PID's reading shows "- - -". Once the PID lamp is
warmed up, the display shows the actual value.

11.5 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.
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.
