Combustion oxygen monitor

OI/AZ25P–EN Rev. E

5 Start-up and operation

5.1 Preparation

1. If the probe is not connected permanently to test gas

pipework for automatic calibration purposes, ensure
blanking plugs are securely fitted to the test gas inlet
connections on the probe.

2. If the probe is connected permanently to test gas

pipework for automatic calibration purposes, ensure that
the valve installed in the pipework adjacent to the test gas
connection is closed.

3. Check the connections on both the probe and the

transmitter.

Test gas connections must be checked for leak-tight
joints. Leaks, especially on permanently pressurized
AutoCal-fitted probes, can cause errors and drain away
expensive bottles of test gas.

4. Adjust the reference air flow to a stable flow rate between

0.3 and 0.5 l / min (0.64 and 1.06 scfh) for probes without
restrictors or 1 bar (15 psi) for probes with restrictors.

–

refer to Section 3.5.5 and 3.5.6, page 13 for probes
fitted with AutoCal.

–

refer to Section 3.5.7, page 14 for probes without
AutoCal.

5.2 Setting up test gases

This section prepares the system for manual and automatic
calibration routines by setting up the test gas flows and
pressures to suit different AutoCal / restrictor configurations:

the required test gas flow is 1 l/min (2.118 scfh) for all
configurations

refer to Section 3.5, page 9 for test gas and reference air
supply configurations

5.2.1 AutoCal System with restrictors

To set up an AutoCal system with restrictors:

1. Make test gas and reference air connections as detailed in

Section 3.5.5, page 12.

2. Turn on Test Gas 1 and set the pressure to a nominal

1 bar  (15  psi).

3. At the transmitter, check the 

Calibrate / AutoCal Hardware

/ Hardware Type

 parameter is set to 

Internal

.

4. At the transmitter, open the 

Test Gas 1

 valve by selecting:

Calibrate / AutoCal Hardware / Valve Manual Control /
Test Gas 1

 

and pressing

 

 

to open the valve

.

A small icon is displayed to indicate the valve is in the

Open

 position:

5. Fine tune Test Gas 1 pressure to 1 bar (15 psi) – this

ensures the correct flow through the restrictors.

6. Turn gas off at the transmitter by pressing

 

, then turn

Test Gas 1 off at the supply.

7. Repeat steps 2 to 6 for Test Gas 2 (if present).

8. Refer to IM/AZ20E-EN to perform a calibration when

required.

Caution.

If the test gas connection is not sealed

when not in use, air leaking into the probe via the
connection causes measurement errors. In a
pressurized flue, gases venting to atmosphere
through the connection cause corrosion of, and / or
block, the test gas tube. In a negative pressure flue,
air leakage causes high O

2

 reading errors.

Note.

Only perform a final system calibration after the 

probe has been thermally stable for 2 hours.

Note.

The following sections assume the transmitter is

energized and the probe at working temperature (above
600 °C), the reference air supply is on and test gases are
available.
