16. Diagnostic Mode
In Diagnostic Mode, the MicroRAE provides raw counts for sensor, battery, and other readings,
as well as a list of installed sensors and information about them (expiration date, serial number,
etc.). Most of these screens are useful only to service technicians. Many allow access for
changing settings.
The MicroRAE’s Diagnostic Mode can only be accessed at startup time. In Diagnostic Mode,
MicroRAE displays readings in raw counts instead of units such as parts per million (ppm) or
other units of measure.
16.1.
Entering Diagnostic Mode
1.
With the MicroRAE turned off, press and hold both [MODE] and [Y/+].
2.
When the display turns on and the password screen appears, release the keys.
3.
Enter the 4-digit password (the password is the same as the one for the Programming
Mode; the default password is 0000).
•
Step from one position in the four-character string to the other by pressing [MODE].
•
Press [Y/+] repeatedly to select a desired number. Numbers increase from 0 to 9.
•
Once 9 is reached, pressing [Y/+] again “wraps” around back to 0.
4.
When you are done, press [MODE] followed by [Y/+]. If you input the correct password,
the instrument restarts in normal reading mode.
16.2.
Exiting Diagnostic Mode
1.
Turn off the MicroRAE by pressing and holding [MODE]. There will be a standard
shutoff countdown.
2.
When the instrument shuts off, you will be alerted. Release your finger.
Note:
The next time you start MicroRAE, hold only [MODE], and it will automatically start in
Normal Mode.
