Measuring Mode, Alarms
This section covers alarm indications in Measuring Mode. It also describes how to reset
the GX-6000 after an alarm has occurred and how to respond to an alarm condition.
NOTE:
False alarms may be caused by radio frequency (RF) or electromagnetic (EMI)
interference. Keep the GX-6000 away from RF and EMI sources such as radio
transmitters or large motors.
Alarm Indications
The GX-6000 buzzer will sound an alarm, the LEDs will flash, and the vibrator will pulse
when any sort of alarm condition or failure is encountered.
NOTE:
If an alarm condition occurs while you are in Display Mode, the GX-6000 will
automatically bring up the alarm screen instead.
The table below summarizes the types of alarms produced by the GX-6000 and their
indications.
None of the Man Down alarm indications will happen if
MAN DOWN
is set to
OFF
in
Maintenance Mode (factory setting).
