1 Maintenance and repair
The Sensistor XRS9012 is maintenance
free, except for battery replacement (normal-
ly every three years). This section describes
the functions of the instrument and gives
advice as how to function tests should be
carried out.
1.1 Function and controls
Following functions are controlled from the
panel:
- Sensitivity: can be varied in 10 steps, each
step doubles the sensitivity.
- On/Off: the detector has an automatic
switch-off aftr 30 minutes of no activity.
- Battery Check: At least 8 of the light emit-
ting diods (LED) will illuminate at full
charge. Full charge takes one hour.
- Zero: the detector has an automatic zero-
ing function. The ZERO button allows the
operator to force the signal to zero instanta-
neously.
- Sound level: the volume can be changed in
64 steps.
- Earphone output
- MAX: this is a peak-hold function allow-
ing the operator to compare the maximum
gas signal in two different places.
- SEARCH (default): this is the normal
mode where the signal follows the gas con-
centration. The detector always starts in this
