Conventions in this document

Incorrect calibration
CAUTION: An incorrect calibration leads to incorrect
measured values.
► CSA requirement (Canadian Standard Association): The
sensitivity must be checked daily before first using the
device, with a known concentration of the gas to be
measured that corresponds to 25 to 50 % of the final
concentration. The accuracy must be 0 to +20 % of the
actual value. The accuracy can be corrected by
calibration.
RFID tag (optional)
► The RFID tag must not be read out in explosion-hazard
areas.
NOTICE
Damage to the CatEx sensor!
Fractions of catalytic poisons in the measuring gas (e.g.
volatile silicon, sulphur, heavy metal compounds or
halogenated hydrocarbon) can damage the Cat Ex sensor.
► If the CatEx sensor can no longer be calibrated to the
target concentration, replace the sensor.
DrägerSensor CatEx 125 PR (6812950) and CatEx 125 PR
Gas (6813080)
► For this gas detector, only use sensors with serial
numbers > ARLB XXXX (starting with date of manufacture
in February 2018). These sensors are certified for use in
zone 0, T4.
When using the PID sensor
► To ensure safe operation, the gas detector must not be
switched on at temperatures below -10 °C when using the
PID sensor (6813475/6813500).

Glossary

Term Description
Operation signal A periodic optical (green LED) and/or
acoustic signal.
Measurement Measurement in one of the applications
mode (monitoring, clearance measurement,
leak search, benzene/pre-tube measure-
ment) (X-am 8000 only).
Monitoring Monitoring without pump (diffusion)
Monitoring with pump (with pump
adapter)
Capture range The capture range refers to a measured
value range within which minor variations
in measured values (such as signal
noise, variations in concentration) do not
cause variations in the display. Measured
values outside the capture range will be
displayed with the actual measured
value.
Confined space Measurement with pump and any acces-
entry wizard sories (e.g. hose, probe) for clearance
measurements of specific areas (X-am
8000 only).
Leak search wiz- Leak search measurement (X-am 8000
ard only)
Benzene/pre- Benzene/pre-tube measurement (X-am
tube wizard 8000 only)
Peak Peak value
Quick bump test Test for alarm triggering.
Extended bump Test for accuracy and alarm triggering.
