1 Intended use
SNOOPER mini is a gas detector for plumbers and service technicians for detecting leaks at free
laid gas pipes.
Fields of application (for example):
zDetectionofgasleaksbydirectlyinspectingjointsof:pipes,ttings,anges,threadedconnections,
pressure reducers, etc.
zLeak detection at openly routed natural gas pipelines in buildings
zInspection of covered gas pipelines at the gas discharge locations
zInspectionatthehouseservicetting
CAUTION! Danger of life!
SNOOPER mini must not be used as a gas warning instrument.
It is not suitable for checking whether the ambient air or the air inside pits and sewers
is approaching the lower explosion level (LEL).

2 Device variants
The device is available in two different versions:
zwithexibleswanneck
zwithhandsensor(spiralcable,handle,exibleswanneck)
Both device variants are operated the same way.
The device is available for the following types of gas: zMethane CH4
zPropane C3H8
zHydrogen H2
Note:
The type of gas is indicated on the rear of the device. It is not possible to change it.

31
English
3 Safety instructions
zNever open the housing (only exception: the battery compartment). Otherwise, all warranty claims
expire.
zThe swan neck cannot be disassembled. It must not be bent in a sharp angle. The maximum
permissible angle is 90 degrees.
zNever carry the device at the swan neck and/or the hand sensor!
zPrevent that the swan neck comes into contact with water. Water destroys the sensor!

4.2 Operating modes
The device can be used in two different modes:
zMeasurement > see chapter 5
zAdjustment > see chapter 6
4.3 Measuring range
The device operates with a single measuring range, but two different units of measurement (parts per
million [ppm], percent by volume [vol.%]). The device automatically switches between the different
units of measurement.
Conversion: 10,000 ppm = 1 vol.%
Indication of
measurement values in
Limits Resolution
ppm 0 – 100 ppm 5 ppm
ppm > 100 – 2,000 ppm 50 ppm
percent by volume CH4, C3H8: > 2,000 – 22,000 ppm (0.2 – 2.2 vol.%) 0.2 vol.%
H2: > 2,000 – 10,000 ppm (0.2 – 1.0 vol.%)

35
English
4.4 Automatic power-off
SNOOPER mini switches itself off automatically,
zas soon as the battery charge is no longer sufcient. (BATwillbeindicatedbrieyonthedisplay.)
The automatic power-off may also occur immediately after switching on the device! Exchange or
recharge batteries (see chapter 7.4).
zif the device is not operated for 20 minutes (i. e. no key is pressed) or if the display is not chang-
ing. (APFwillbeindicatedbrieyonthedisplay.)
4.5 Display illumination
The device automatically switches on the display illumination:
zif a key is pressed (duration of illumination 20 s),
zif the gas concentration is higher than 25 ppm.

5 Measurement mode
5.1 How to start the measurement mode
Note:
The device must always be switched on in an unpolluted environment (e. g. in the
fresh air).
What to do? What happens? Why? Indication on
the display
1.
press for approx. 2 s
Device is switched on,
audible signal sounds
2. wait Displayashes,
time bar runs out
Heating period,
approx. 20 s

37
English
3. Device ready for
measuring
Note:
After switching on, the device needs one minute to recognise whether it is operated with
disposable or rechargeable batteries. After this check, the battery icon is indicated.

38
English
5.2 Increased gas concentration
An automatic audio signal makes the user always aware of an increased gas concentration.
Audible signal of the device (loudspeaker key)
zswitched on: the interval signal gradually changes to a steady tone
zswitched off: steady tone sounds as soon as the device measures a value higher than 1 vol.%
5.3 Setting the zero point – when and how?
When working with the SNOOPER mini, the zero point may start to drift (e. g. if the device is ready
for measuring and put aside for some time). In this case, the display indicates a value deviating from
zero.
zPress briey on the ON/OFF key. ZRO is indicated on the display. The device is ready to reset
the zero point.
zRe-press briey on the ON/OFF key within 5 seconds. The zero point is reset.

39
English
5.4 Verifying the indication accuracy – when and how?
Accordingto DVGWregulations(DVGW:Germantechnical andscienticassociation forgasand
water), it is required to check the indication accuracy in intervals ranging from every week to every
six months – depending on the frequency of usage and experience.
Gas type of the device Test gas Permissible range
Methane 1 vol.% CH40.8 – 1.4 vol.%
Propane 1 vol.% C3H8
Hydrogen 1,000 ppm H2800 – 1,400 ppm
zThe device must be ready for measuring (see chapter 5.1).
zApply test gas with the help of a suitable test set (e. g. SPE-Y).
zCompare the deviations indicated by the device with the permissible values in the table. If the values
are outside the permissible range, you need to perform an adjustment (see chapter 6).

40
English
6 Adjustment
The device must be adjusted if the deviation of the indication accuracy is outside the permissible
range (see chapter 5.4).
6.1 Tools and requirements
Required tools:
zSuitable test set (e. g. SPE HG, SPE-Y)
zTest head
zTest gas, depending on the type of gas of the relevant device (see table in chapter 5.4)
Youcanndallinformationonhowtoconnectthetestsettothedeviceintheoperatinginstructions
