Decommissioning
A used sintered element must not be reused.
Impacts of decommissioning on the plant to be monitored are not part of this
description.
The decommissioning is done by switching off the operating voltage. Programmed data and parameters are
not lost. If the gas detector is set into operation again after a prolonged shutdown, it will be necessary to
perform recommissioning according to chapter 5.

Definitions
Warm-up time (stabilization time)
Time span from switching on the device PX2 in a specific atmosphere to the moment when the measured
value reaches the specified deviations and is stable.
Reaction time
Time up to which a predetermined reaction (display of reading or alarm) of the gas warning device can be
observed.
Run-in time
Time the sensor head needs to be supplied continuously with the operating voltage for stabilisation before
calibration.
Response time t90
Time span from the occurrence of a gas mixture at the gas inlet to the moment when the display shows 90
%.
Zero gas
Test gas containing neither the target gas nor troublesome impurities (synthetic air: 20% O
2
, rest N).
Target gas
Gaseous substance to be determined in the measurement gas and to be warned against.
Test gas
Gas mixture of known composition used for testing and calibrating the PX 2 sensor head.
