5 Calibrating the instrument
 Adjustment may not be possible due to instrument and
channel errors.
 Allow the sensor to warm up before the adjustment.
 Warm-up time: see Instructions for Use/data sheet for the
installed DrägerSensor.
5.1 Adjustment interval:
 Observe the relevant specifications in the Instructions for
Use/data sheet for the DrägerSensor installed.
 For critical applications according to EN 60079-29-2
1
or
EN 45544-4
2
and national regulations.
 Improvement of zero point accuracy – perform a fresh air
adjustment, see "Performing a fresh air adjustment" on
page 15.
5.2 Performing a fresh air adjustment
A fresh air adjustment can be performed to improve the zero
point accuracy.
 Calibrate the instrument to fresh air, free of measured
gases or other interfering gases.
 The zero point of the sensor is set to 0 during the fresh
air calibration.
 Sensors that are faulty or not warmed-up will prevent the
adjustment.
 In the case of sensors which are in the warm-up phase,
the message » 159 « is displayed with the special
symbol » « (for warning message).
 In the case of a sensor or instrument error, the
message » 109 « is displayed with the special symbol
» « (for a fault message).
 The message is cleared after 5 seconds and the
