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):
z
Detection of gas leaks by directly inspecting joints of: pipes, ttings, anges, threaded connections,
pressure reducers, etc.
z
Leak detection at openly routed natural gas pipelines in buildings
z
Inspection of covered gas pipelines at the gas discharge locations
z
Inspection 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).

English
2 Device variants
The device is available in two different versions:
SNOOPER mini z > with exible swan neck
SNOOPER mini H z > with 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: Methane CH
z
Propane C z
Hydrogen H z

3H8
2
Note:
The type of gas is indicated on the rear of the device. It is not possible to change it.
About these operating instructions: Texts and illustrations usually refer to the
SNOOPER mini
calibrated to methane. Generally, they also apply to the SNOOPER mini H and to the other gas types, propane and hydrogen.

3 Safety instructions
Never open the housing (only exception: the battery compartment). Otherwise, all warranty claims z
expire.
z
The swan neck cannot be disassembled. It must not be bent in a sharp angle. The maximum
permissible angle is 90 degrees.
Never carry the device at the swan neck and/or the hand sensor! z
z
Prevent that the swan neck comes into contact with water. Water destroys the sensor!

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.

5.4 Verifying the indication accuracy – when and how?
According to DVGW regulations (DVGW: German technical and scientic 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.% CH
Propane 1 vol.% C
4
0.8 – 1.4 vol.%
3H8
Hydrogen 1,000 ppm H2800 – 1,400 ppm
The device must be ready for measuring (see chapter 5.1). z
Apply test gas with the help of a suitable test set (e. g. SPE-Y). z
z
Compare 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).
English
39
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:
Suitable test set (e. g. SPE HG, SPE-Y) z
z
Test head
z
