3 Measuring operation
Note:
In the
GAS-WARNING
mode the following remarks
should be observed during operation at degrees be-
low zero, high temperatures and high humidity:
Degrees below zero lead to a diminished display
(up to 4 % LEL at -10 °C) at the zero-point of the
methane and propane sensor. This can be com-
pensated by a correspondingly lower adjustment
of the alarm thresholds.
When adjusting the methane sensor with dry gas,
high temperatures and high relative humidity (> 90 %)
could lead to a diminished display (up to 30 % of
measuring value). This can be compensated by
a correspondingly lower adjustment of the alarm
thresholds.
Note:
After triggering the AL3 alarm in the CO- or H
2
S-
measuring range, the instrument must be inspected
before any further use (cf. section 5.1: Function
testing, testing display accuracy, maintenance).
