Terms of Warranty
Megger accept responsibility for a claim under warranty brought forward by a
customer for a product sold by Megger under the terms stated below.
Megger warrant that at the time of delivery Megger products are free from man-
ufacturing or material defects which might considerably reduce their value or us-
ability. This warranty does not apply to faults in the software supplied. During the
period of warranty, Megger agree to repair faulty parts or replace them with new
parts or parts as new (with the same usability and life as new parts) according to
their choice.
This warranty does not cover wear parts, lamps, fuses, batteries and accumula-
tors.
Megger reject all further claims under warranty, in particular those from conse-
quential damage. Each component and product replaced in accordance with this
warranty becomes the property of Megger.
All warranty claims versus Megger are hereby limited to a period of 12 months
from the date of delivery. Each component supplied by Megger within the context
of warranty will also be covered by this warranty for the remaining period of time
but for 90 days at least.
Each measure to remedy a claim under warranty shall exclusively be carried out
by Megger or an authorized service station.
This warranty does not apply to any fault or damage caused by exposing a prod-
uct to conditions not in accordance with this specification, by storing, transporting,
or using it improperly, or having it serviced or installed by a workshop not author-
ized by Megger. All responsibility is disclaimed for damage due to wear, will of
God, or connection to foreign components.
For damage resulting from a violation of their duty to repair or re-supply items,
Megger can be made liable only in case of severe negligence or intention. Any
liability for slight negligence is disclaimed.
Since some states do not allow the exclusion or limitation of an implied warranty
or of consequential damage, the limitations of liability described above perhaps
may not apply to you.

2. Areas of application/intended use
Warning of possible health hazard! Only use the device if you
have inspected the surroundings/location by means of an on-site
safety inspection and assessment before starting the work.
The Fault Sniffer 2 measuring device is used to locate cable faults in underground
low-voltage networks while above ground, without removing the corresponding
power line from the mains power supply. The dual sensor installed in the device
reacts to the appropriate gases.
When and for what may the device be used?
The use is limited to the detection of cable faults and cannot be used to assess
hazards.
The device is not approved for use in zones with a risk of explosion.
The device must not be used for explosive mixtures.
How should the device be stored in case of prolonged non-use?
If the Fault Sniffer 2 is not used for an extended period of time, the battery should
be stored at between -20°C and +50°C for 30 days and at between -20°C and
+30°C for one year.
If the device has not been used for a long period of time, it should be prepared
before the next use:
1. Switch on the device.
2. Select the Cable fault detection menu item.
3. Let the device run in the fresh air for about 1 hour.
4. Then perform a calibration and, if necessary, an adjustment (see Chapter 9).
