PurposePurpose
Purpose
The EX-TEC® SNOOPER H gas detector is intended for the
following purposes:
lleak detection in spaces, shafts or channels
linspecting new installations or repairs
llocating leaks in installation pipes
linspecting fittings, flanges, threads or seams
A smell of gas may possibly be due to gas penetration of the
building or space via gaps in walls, cable ducts or other routes.
These should also be inspected.
If the continuous acoustic signal (item 3) sounds and the
measurement-range limit of 1.00 vol.% is displayed (item 2) on
entering a space (e.g. a building, shaft, channel or the like), then
the following precautionary measures must be taken:

A maximum of 3 charging adapters with no

The detector has a microprocessor-controlled heuristic operating-
hours account.
If the detector is not stored in the charging adapter the NiCd battery
will spontaneously discharge.
In order to verify the capacity of the NiCd battery we recommend
youtooperate thedetectoruntiltheundervoltage alarm istriggered

Charging
Place the EX-TEC® SNOOPER H (switched off) in the charging
adapter. They are connected via the charging contacts (item 7) and
the adapter contacts (item 2 in the illustration on page 14). An
acoustic signal sounds to indicate the start of charging.
The charging period required is calculated from the operating
hours and a display of the following type appears:
lthe detector has 5 operating hours left (=
5 bars) and will take 3 hours to become
fully charged
lif it is fully charged all the bars are visible
and the number display disappears
lthe detector can be left in the charger

If the detector is not connected to the charger when switched off,

The EX-TEC® SNOOPER H is factory-set with test gas. You can
adjust the detector using an appropriate test gas.
To carry out the adjustment you need:

the SPE test set
the SNOOPER H or SNOOPER H small test head
1.00 vol.% methane or propane test gas in synthetic air
the adjusting pin
