Alarm Operation
The HIGH and LOW Alarm limits are user programmable as described in the OPERATION
(SETTINGS) section. Note that the High Alarm limit cannot be set lower than the Low Alarm limit
and the Low Alarm Limit cannot be set higher than the High Alarm limit.
When an alarm is set to ON in the SETTINGS mode, the analyzer will indicate the alarm symbol
(high or low) in black with the associated alarm value on the display (see the Display Icons
section).
Once the high and low alarm limits are set, the analyzer will audibly and/or visually alarm (in
flashing red) when a measurement limit is exceeded. Note that if the SOUND setting is turned
OFF in the SETTINGS mode, only the visual alarm will trigger.
To silence an alarm, go to the ALARM sub-menu in the SETTINGS menu and select OFF for the
alarm SOUND setting.
