7. Turning The MicroRAE On And Off
7.1. Turning The MicroRAE On
With the instrument turned off, press and hold the [MODE] key until the audible alarm stops, and
then release.
When starting up, the MicroRAE turns the backlight on and off, beeps once, blinks once, and
vibrates once. A RAE Systems logo should appear first. During a normal startup, this is followed
by a progression of screens that tell you the MicroRAE’s current settings.
Then the MicroRAE’s main reading screen appears. It takes 45 seconds for some sensors to show
a reading, so if any have not warmed up by the time the main screen is shown, you will see “- -”
instead of a numerical value until the sensor provides data (if you turn a sensor off and on again,
it also shows “- -” for up to 45 seconds). Then it displays instantaneous readings similar to the
following screen (depending on the sensors installed) and is ready for use.
Note:
If the battery is completely empty, the MicroRAE shuts off. You should charge the before
turning it on again.
IMPORTANT!
If a major error that prevents the MicroRAE from functioning is found during startup, the
message “Contact Service” is shown on the display. The instrument should be shut off and
serviced.
7.2. Turning The MicroRAE 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 MicroRAE is powered off.
Caution:
The alarm is very loud. During startup, you can mute most of the sound by holding a
finger over the alarm port. Do not put tape over the alarm port to permanently mute it.
