1 Maintenance and repair
The Sensistor XRS9012 is maintenance
free, except for battery replacement (normally 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 emitting diods (LED) will illuminate at full
charge. Full charge takes one hour.
- Zero: the detector has an automatic zeroing function. The ZERO button allows the
operator to force the signal to zero instantaneously.
EN
- Sound level: the volume can be changed in
64 steps.
- Earphone output
- MAX: this is a peak-hold function allowing 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 concentration. The detector always starts in this

1.1.2 Battery charger
EN
The voltage range for charging is 9 15VDC. To operate on mains voltage
a voltage converter is connected to the
power input at the back of the unit.
There is also a possibility to connect
the unit to the car cigarettelighter,
which enables the unit to be charged
in the car.
1.1.3 Probe attachment
All probes are attached to the Leak
Detector Sensistor XRS9012 via cable
C21 to the socket at the back of the
unit.

1.2 Changing batteries
Before reading this section, please
see picture on page 11 to get an overview of the assembly.
We recommend changing batteries
every three years (batteries will normaly last for several more years but
operation time is shortened).
Follow the procedure described
below. The batteries are placed inside
the Leak Detector.
Remove the four screws holding the
back cover
Remove the cover carefully

Disconnect the exible cable
from the probe connector
