Errors/Complications during the Calibration
Result of the sensitivity (span) calibration:
Deviation from the last
stored calibration value:
Green flashes at a
single rhythm.
Maintenance
signal
≤5 % of the last calibra-
tion value (configurable)
Green flashes at a
double rhythm.
Maintenance
signal
>7.5 % to ≤15 % of the last
stored calibration value
Green flashes at a
triple rhythm.
Maintenance
signal
>15 % of the last stored
calibration value ≈30 minutes
Carry out the sensitivity (span) calibration:
Place the magnetic
wand onto the mark
» S «.
Green and yellow
are on.
Maintenance
signal
Acknowledge the adjust-
ment.
Remove the magnetic
wand.
Green/yellow flash
alternately.
Maintenance
signal
The gas transmitter waits
with the termination of the
calibration until the gas
concentration is the same
as prior to calibration with
an accuracy of ±5 % of the
measured value.
≈30 minutes
Attention: Remove calibration adapter
PIR 7000. Turn off the calibration gas.
Make sure that the gas transmitter is no
longer being purged with the
corresponding calibration gas.
Measuring mode is automatically
activated after finishing calibration.

quickly.
Maintenance
signal
Device has an error or has
detected complications.
≈30 minutes
Attention: Turn off the calibration gas.
Remove calibration adapter Dräger
PIR 7000.
Place the magnetic
wand onto the mark
» 0 « when calibrating
the zero-point or onto
the mark » S « during
span calibration.
Green and yellow
are on.
Maintenance
signal
Display of device’s error is
acknowledged.
Remove the magne-
tic wand.
Green/yellow flash
alternately and
slowly.
Maintenance
signal
The measuring mode is
activated with previous
settings for zero-point
and/or span.
