OPERATION
Note: The maximum and minimum values are cleared from
the instrument's memory when you press and hold the
green (RH) button
in non-alarm state. The display
returns to the normal operating display if no button is
pressed.
2.5 ALARMS RESET OR ACKNOWLEDGE
When the instrument detects an alarm set point has been
reached, the audible and visual alarm will be activated to
alert the user.
Caution: Never remove the battery to silence an
alarm as this can damage the instrument.
The alarms are individually programmable to be either
Latching, (i.e. alarm will stay on until the user resets by a
press and hold of the green (RH) button
when the gas
reading has returned within the preset alarm limits), or
Non-Latching (i.e. the audible and visual alarm will reset
automatically when the reading returns within the preset
alarm limits).
Note: Default alarms are set in accordance with current
international standards.
