General Operation
Gas Monitoring Screen
The primary operating screen is the Gas Monitoring screen. The Gas Monitoring
screen may utilize one of three displays:
Concentration in PPM (for toxic sensors)
Concentration in Percent Volume (for oxygen sensors)
Gas Sensor type only (selectable for either sensor type).
The Enter button activates the backlight and initiates IR print.
In the presence of a gas concentration that
exceeds the low or high level threshold, the
instrument will enter an alarm screen. Alarm
detection in any of the instrument’s normal
operating screens – the battery life, peak, or
initiate print screens – will force a transition
back to the Gas Monitoring screen. The alarm
screen is indicated on the display by the Alarm
Indicator and either the Up Indicator or Down
Indicator which designate a low or high alarm.
High Alarm Screen
These icons are in addition to the values and icons normally displayed in the
current monitoring screen. From this screen, the Mode button can toggle through
the menus.
