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).
