Gas Analyzer Calibration

Section A

Principles

Calibration Control

Depending on the gas analyzer version and equipment, there are three methods
for controlling calibration:

•

Manual calibration

•

Automatic calibration

•

Externally controlled calibration

All analyzer modules can be calibrated using any of the three methods.
See Section C, “Notes for Calibrating Analyzer Modules” for details.

Calibration Start

•

Manual calibration is started manually via the gas analyzer’s display and control

unit.

•

Automatic calibration is started at time intervals determined by the internal clock

or by an external control signal or manually via the gas analyzer’s display and
control unit.

•

Externally controlled calibration is triggered by an external control signal.

Warm-up Phase

Calibration should only be started after the warm-up phase.

Analyzer Module

Warm-Up Phase Duration

Caldos25 1.5

hours

Caldos27

Approx. 30 / 60 minutes for class 1/ 2 measurement ranges

Limas11

Approx. 2.5 hours

Magnos206

≤

1 hour

Magnos27

2 to 4 hours

Uras26

Approx 0.5 / 2 hours without / with thermostat

Plausibility Test in
Calibration

If during calibration the gas analyzer finds implausible values (e.g. if the span and
zero values are equal), calibration is stopped and an error message is generated.
The values stored after the last calibration remain in effect.

Status Signal

The “Maintenance Mode” status signal is set during calibration.
