1C INTRODUCTION
The commissioning and calibration procedures detailed in this
manual are additional to those in the operating instructions
(ZMT/0011) and are usually carried out prior to despatch.
If however, any of the following is required, the commissioning
set-up and calibration can be checked:
A change to instrument operation.
Inclusion of additional features, e.g. relay and/or
retransmission outputs.
Confirmation of calibration settings, e.g. if instrument
response or readings are suspect.
An internal switch is used to prevent tampering with the
commissioning and calibration settings - see Section 2.1C.
The Commissioning Page is used for initial analyser set-up
to suit individual applications (usually specified at the time of
ordering). The page facilitates the introduction of additional
parameters/pages or the omission of non-applicable
parameters/pages from the overall programme chart (Fig. 10
in ZMT/0011), e.g. the analogue retransmission page is omitted
if retransmission outputs are not used. A summary of the
Commissioning Page parameters is shown in Fig. 3.1C
overleaf.
The Electrical Calibration Parameters are contained within
the Commissioning Page and are used for calibrating the
oxygen and thermocouple inputs.
parameters are also incorporated in the analogue
retransmission and carbon dioxide/monoxide page for their
respective calibrations.

2C PREPARATION
2.1C Access to Commissioning Page and Calibration
Parameters - Fig. 2.1C
The Commissioning Page and Calibration Parameters are
enabled/disabled by a pair of rocker switches located inside
the analyser. For access to the switches:
1 Unlock and open the door.
2 Identify the switches.
3 Set the positions of both switches as required.
N.B.
Ensure that the switches are disabled after any
commissioning or calibration checks/changes to prevent any
tampering with the settings.
