Turning the AreaRAE Plus/Pro Off
Press and hold [MODE]. A 5-second countdown to shutoff begins. You must hold your finger on
the key for the entire shutoff process until the AreaRAE Plus/Pro is powered off.
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 Honeywell distributor for technical support.
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 Honeywell 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 PID, if the pump is in alarm for more than
five minutes, the PID lamp automatically turns off. The display shows 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.
