Calibration control
Function
In the “Calibration control” menu you can determine the start and sequence of calibration
procedures and also decide whether the “Calibration block” control input should serve to
start automatic calibration.

C a l . m o d
M a n u a l
Calibration is only started and monitored by the
operator with a menu function
1
1 = Standard setting set at manufacturer's works
a u t o
Automatic calibration starts automatically at the set
times (
→ P. 150, §12.4.3 ) (manual calibration is still
possible)
e x . a u t o
Automatic calibration is started via the “Calibration
block” control input (
→ P. 65, §6.3.6 )
e x . S t e u without function
M R Z e r o
Measuring range in which the zero gas is measured 2
2
Recommendation: Smallest measuring range used in measurement mode. Instrument air must be pure enough for
the selected measuring range (specifications → P. 194, §16.6.1).
M R S p a n Measuring range in which the span gas is measured

3 “Typical setting” for emission measurement: 2: for LEL measurement; 5
M a x c a l i b
d u r a t i o n
Specifies how long the EuroFID tries to find a constant measured
value (average value) with a calibration gas which can be used for
calibration. If this is not possible within the “Max. calib duration”,
calibration is canceled and a malfunction message is activated.

Y e s
After each start-up (also after stand-by), the EuroFID
starts automatic calibration as soon as the
operational state is reached.
N O No automatic calibration starts after start-up.
