4.1 GAS ALARMS
Gas alarms are enabled when the instrument is switched on
and warm-up is complete.
All gas ranges have alarm limits that trigger the alarm if the
measured gas value exceeds the set level. If a preset alarm
level is exceeded, the instrument vibrates, the display
backlight illuminates red, the audible alarm sounds, the LED’s
flash red and the gas range in alarm flashes on the display.
The alarms are individually programmable to be either
‘Latching’ or ‘Non-Latching’.
A ‘Latching’ alarm will stay on until reset by the user with a
press and hold of the Right Hand (RH) button
when
the gas readings are safe.
A ‘Non-Latching’ alarm will reset automatically when the gas
readings are safe.
The following table illustrates the factory default alarm
