AreaRAE Plus & AreaRAE Pro User's Guide

19 Diagnostic Mode

In Diagnostic Mode, the AreaRAE Plus/Pro 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.
Diagnostic Mode can only be accessed at startup time. In Diagnostic Mode, readings are displayed in raw
counts instead of parts per million (ppm) or other units of measure.

19.1 Enter Diagnostic Mode

1. With the instrument turned off, press and hold [Y/+] and [MODE] until the AreaRAE Plus/Pro
starts up.
2. After startup, enter the password when prompted (default is "0000") and press [MODE].
Once Diagnostic Mode is active, step from screen to screen by pressing [N/-].
19.2 Adjusting Alarm LEDs & Buzzer
The buzzer, green LEDs, red LEDs, and backlight can be turned on or off in Diagnostic mode. In
addition, you can adjust the repetition rate and loudness of the buzzer and the repetition rate and
brightness of the LEDs.
1. Start with the instrument turned off. Hold down the [Y/+] and [MODE] keys until the AreaRAE
Plus/Pro starts.
2. When you see the password screen, input your 4-digit password, and then press [MODE].
3. Once you have entered Diagnostic Mode, press [N/-] until the "Alarm" screen is displayed.

Plus/Pro starts.

3. Once you have entered Diagnostic Mode, press [N/-] until the "LCD Contrast" screen is
displayed.

19.4 Pump Stall Threshold Adjustment

Proper setting of the pump stall threshold is necessary so that if there is an obstruction to the inlet, the
pump will stop and the instrument will go into alarm. This prevents unwanted debris or liquid from
entering the pump and causing disruption or damage. The AreaRAE Plus/Pro provides two methods to set
the pump stall threshold: Static and Dynamic.
Note: The Dynamic method uses an algorithm that takes external temperature into consideration for
greater accuracy.
