If it is necessary to set the pump stall threshold, you must enter Diagnostic Mode. Also, regardless of
which method is used, when you are done setting thresholds, exit Diagnostic Mode and test the
instrument before actual use.
19.4.1 Entering Diagnostic Mode To Set The Pump Stall Threshold
5. Start with the instrument turned off. Hold down the [Y/+] and [MODE] keys until the AreaRAE
Plus/Pro starts.
6. When you see the password screen, input your 4-digit password, and then press [MODE].
7. Once you have entered Diagnostic Mode, press [N/-] until the “Pump” screen is displayed.
8. Set the high and low threshold settings for pump stall using the instructions in this section. Press
[MODE] to step through the menu items; press [Y/+] to make a change, and press [N/-] to
advance to the next menu.
19.4.2 Selecting The Pump Stall Threshold Method
At the Pump screen, the settings are shown, including the Pump Speed and Pump Stall Algorithm (which
can be Dynamic or Static).
To change the pump Speed or Stall Algorithm setting:
1. Press [MODE]. Either the pump Speed or the Stall Algorithm is highlighted.
2. To change from “High” to “Low” or “Dynamic” to “Static,” press [Y/+].
Important! The pump Speed must be set to “High” in order to access Dynamic pump stall settings.
Now follow directions to change the pump stall threshold values, using the method that matches your
choice of either Dynamic or Static.
