WARNING: ANY NEW SENSOR FITTED TO A DEVICE WILL TAKE TIME TO
SETTLE TO A STABLE READING. FOR THIS REASON, ONCE
THE SENSOR HAS BEEN FITTED, THE DEVICE SHOULD BE
LEFT UN-POWERED FOR AT LEAST 2 HOURS BEFORE
ATTEMPTING TO POWER-UP AND CALIBRATE.
16]
Once the sensor has been allowed to settle, replace the batteries and fit the
battery cover.

Power the device and allow the sensor(s) to warm up. The new oxygen sensor
will require calibration and may be showing a fault due to an over-range reading
(this is possible for a new sensor). To calibrate the oxygen sensor, follow the
instructions in the section 7.2.
NOTE:
THE OXYGEN SENSOR MAY REQUIRE FURTHER FRESH AIR
CALIBRATIONS AS THE SENSOR CONTINUES TO SETTLE. THE
OXYGEN READING SHOULD BE CHECKED FREQUENTLY IN
FRESH AIR DURING THE FIRST FEW HOURS OF OPERATION
WITH A NEW OXYGEN SENSOR.
To ensure the sensor replacement reminder ( icon) occurs at the correct time for the new
sensor, the reminder should be reset using the Aspida configuration software. See the
Aspida
software configuration manual for instructions.
