58 EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A
Calibrating the gas analyzer
Calibration control
Manual and automatic calibration
Manual calibration
The manual calibration (see page 68) is normally controlled on the display
and operator control unit of the gas analyzer. It is carried out individually for
each sample component.
Automatic calibration
The automatic calibration (see page 62) is started cyclically on a time inter-
val basis by the internal clock of the gas analyzer. It is carried out jointly for
all sample components
Automatic calibration can also be started by an external control signal or via
the Modbus

or manually on the display and operator control unit of the gas
analyzer.
Automatic calibration can be disabled by an external control signal or via the
Modbus.
Status signal during the calibration
The status signal "Maintenance mode" is active during the calibration.
In automatic calibration, this is the interval from the gas change sample gas
test gas until the end of the longest pre-set low pass time constants (see
page 90) plus the purging time (see page 63) after the following gas change
test gas sample gas.
There are two possibilities in the case of manual calibration:
If no valves are configured, the status signal is cleared on exiting the
calibration menu.
If at least one sample gas valve (or a digital output with a valve function)
has been configured, the status signal is cleared at the end of the long-
est low-pass time constant plus the purging time after the following gas
change test gas sample gas.
Depending on the configuration of the signal inputs and outputs (see page
95) the status signal is output to a digital output with the function "Mainte-
nance mode".
Current signal during the calibration
The configurator (see page 63) can be used to set whether the current sig-
nals at the analog outputs
follow the changes in measured values during the calibration or
are held at the last value measured before the start of the calibration.
If the current signals are configured to "Hold", the analog outputs are held
until the status signal "Maintenance mode" has been cleared.
