Action Status display
Display of the span error:
Wait approx. 1 to Green flashes in a
2 minutes until the simple sequence:
yellow status light is
off. The display error
Green flashes in a
can be read from the
double sequence:
flash rhythm of the
green status light.
Green flashes in a
triple sequence:
Adjust the span:
Place the magnetic Green and yellow on Maintenance
wand on the " S "
mark and hold it there.
Remove magnetic Green/yellow flashes
wand. alternately
The gas transmitter terminates the calibration automatically and switches to measurement
mode (after reaching the gas concentration before calibration, accuracy: ±5 %) (green on).
At the end of the calibration or if the timeout is exceeded, shut off calibration gas and if

necessary remove the gas exposure accessories used for calibration.
The factory-set calibration gas and the factory-set calibration concentration are specified on
the configuration label.
If there is a deviation from these settings, the modified parameters must be sent with the Dräger
RAB 7000 remote access box or a PC and the Dräger PolySoft software or a HART
control and checked after read-back. Enter the modified parameters on the configuration label.
The recommended calibration gas concentration is 40 to 60 % of the full-scale deflection.
If the calibration gas or calibration gas concentration are changed, the output value must be
checked when calibration gas is applied for the first time (e. g. on the downstream central device
or during calibration with a PC and the Dräger PolySoft software in the calibration screen).
Errors/complications during the calibration

Yellow flashes quickly Maintenance
Place the magnetic Green and yellow on Maintenance
wand on the " 0 " mark
during zero calibration
or on " S " during span
calibration and hold in
place.
Remove magnetic Green/yellow flashes

Output signal Meaning
Maintenance The display error is less than
signal the defined "calibration range
limit".
Maintenance Minor display error.

Action Status display
The gas transmitter cancels the calibration and switches to measurement mode (green on).
After cancellation of the calibration or if the timeout is exceeded, shut off gas and if

necessary remove the gas exposure accessories used for calibration.
Abort the calibration
Action Status display
Place the magnetic Yellow flashes quickly
wand on the " S " (approx. 2 seconds)
mark during zero
calibration or on " 0 "
during span
calibration and hold
in place.
Green and yellow on Maintenance
Remove magnetic Green/yellow flashes
wand. slowly alternately
The gas transmitter cancels the calibration and switches to measurement mode (green on).
After cancellation of the calibration or if the timeout is exceeded, shut off gas and if

necessary remove the gas exposure accessories used for calibration.
Configuration of the gas transmitter
To individually configure a device the default configuration, use a PC and the Dräger PolySoft
software (see the Instructions for Use of the PC software). Read the configuration back and
check it when configuration is complete.
