set to
ON
(factory setting), pressing and releasing the RESET
SILENCE button silences the buzzer when the GX-2012 is in alarm. The LEDs continue
to flash and the display continues to show the alarm. If the alarms are set up as latching,
when the gas concentration falls below the alarm level, pressing and releasing the RESET
SILENCE button clears all alarm indications for that alarm. If an alarm condition occurs,
you may still enter Display Mode by pressing the DISPLAY (ADJ) button. The buzzer
will be silenced but the LEDs will continue to flash and the unit will continue to vibrate. If
you return to Measuring Mode and there is still an alarm condition, the LEDs will
continue to flash, the unit will continue to vibrate, and the buzzer will remain off. Once the
condition clears, press the RESET SILENCE button to clear the alarm indications.
With
ALM SLNC
set to
OFF
, you cannot silence the buzzer. If an alarm condition occurs,
and you enter Display Mode, the buzzer will not be silenced and the LEDs will continue to
flash. Upon return to Measuring Mode, if there is still an alarm condition and the alarms
are set up as latching, you must wait until it clears before you can press the RESET
SILENCE button to clear the alarm indications.
