Operation
AirLink 6940XP Operator’s Manual
Powering Off
Powering off the device stops the operation of the unit. The Product and Sensor settings, as well
as the operation settings, including the zero and calibration of the sensor, will be unaffected.
1. Press and hold
SUB
for approximately 6 seconds until “OFF” shows on the display screen.
2. The display screen will continue to show “OFF” for the duration of time that the unit is
powered off, as long as uninterrupted power is supplied to the unit.
Faults
In the event of a device failure, a fault code will replace the units of the affected channel. When
the fault is corrected, the device returns to Normal Operating Mode and the affected channel’s
units reappear.
For a list of the fault codes and warning symbols of the AirLink 6940XP and their associated
meanings, see page 53.
Above Background Display Behavior
When any sensor has a reading above its configured background gas level (below for O
2
sensors),
the screen changes to show the reading for that sensor. The AirLink 6940XP will return to Normal
Operating Mode once the background gas is no longer above (below for O2 sensors) the
configured limit.
