Using the Probe for the first time
Before turning on the power supply to the probe, check the following:
• Ensure that a blanking plug has been fitted to the calibration gas connector on
the probe. Air can enter the probe through this connector and cause high O
2
readings. In a pressurized flue, gases venting to atmosphere can cause corro-
sion of the test gas tube.
• Ensure installation has been completed including any optional equipment, for
example, a remote calibration unit.
• Check that all of the connections have been completed.
Warm Up Procedure
1. After a short period the Heater OK LED will begin to flash, indicating the
heater is operating.
2. Until the probe has reached working temperature the probe will default to a
reading of 20.90.
3. The System OK LED will light when the probe has reached working tempera-
ture, this usually takes about 20 minutes.
