SELF-TEST FUNCTION
The Self-Test must not be performed when the tester is connected to the aircraft. Therefore, it is up to the
user to run the Self-Test after ensuring that all three outputs are open to ambient (close to “Ground”) and
all three outputs are in Measure mode.
Note: The Self-Test should be performed each time the tester is to be used on an aircraft, just before
connecting to the aircraft.
To start the Self-Test, press
TEST
. If the conditions for running a Self-Test are not met, the following
message will be displayed in the Lower section.
