Diagnostics
This is located in the AQM PC software. If the AQM is connected to the computer then individual sensor
modules can be interrogated to determine if there is a problem not picked up by normal fault detection as
well as fine tune the sensor performance. Only qualified personnel should use this menu as incorrect use
may result in sensor malfunction. Please consult Aeroqual Technical Support to understand how to use this
feature.
