15. Diagnostic Mode
In Diagnostic Mode, the QRAE 3 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. A few allow access for
changing settings.
The QRAE 3’s Diagnostic Mode can only be accessed at startup time. In Diagnostic Mode, QRAE
3 displays readings in raw counts instead of units such as parts per million (ppm).

Entering Diagnostic Mode
1.
With the QRAE 3 turned off, press and hold both [MODE] and [Y/+].

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.
