RKI Instruments GX-3R - Alarms and Response Actions

GX-3R Operator’s Manual Chapter 3: Operation • 27
Alarms
This section covers alarm indications in Measuring Mode. It also describes responding to and
resetting an alarm condition.
NOTE: False alarms may be caused by radio frequency (RF) or electromagnetic (EMI)
interference. Keep the GX-3R away from RF and EMI sources such as radio
transmitters or large motors.
Alarm Indications
The GX-3R buzzer sounds an alarm, the LEDs flash, and the vibrator pulses when any sort of
alarm condition or failure occurs. If the GX-3R is operating in Stealth Mode, the buzzer does
not sound and the vibrator’s operation depend on the VIB setting in Gas Select Mode’s
STEALTH menu item. See pg.109 for more information.
NOTE: If an alarm condition occurs while you are in Display Mode, the GX-3R
automatically returns to the Measuring Mode screen.
The table below summarizes the types of alarms produced by the GX-3R and their indications.
