Manual calibration means:
Zero and span are calibrated separately by pressing the gas analyzer display and
control unit softkeys.
The test gas supply can be started by activating a multiple path valve.
If the analyzer module is assigned to a gas module and the gas module is fitted
with a single solenoid valve to control the test gas supply (see Fig. 8-A-1), the zero
gas and span gas must be fed to the zero gas inlet (NG). This also applies if an
external solenoid valve is used and controlled via a digital output.
The pump status (on / off during manual calibration) matches the setting for
automatic calibration (see page 8-B-3).

The test gas dew point must be nearly identical to the sample gas dew point.
In analyzer modules with several detectors (e.g. the Uras26) each detector should
be calibrated sequentially.
If the gas analyzer does not have a pressure sensor for air pressure correction, the
air pressure value should be checked and reset as required prior to calibrating the
analyzer module:
• If the gas analyzer's operating site height has been changed since the last
calibration
• If the air pressure effect on the measured value is too high (see also Appendix 2,
"Analyzer Module Operating Specifications").
(For instructions, see "Air Pressure Value Correction" section, page 9-28.)
