Analog earth & insulation tester
Maintenance From time to time, clean your tester using a damp cloth and soapy water. Do not
use abrasive materials or products containing solvents.
Storage If you leave your tester unused for a period of longer than 60 days, remove the
batteries and store them separately.
Unpacking and
repackaging
All equipment has undergone mechanical and electrical testing prior to
dispatching.
However, we recommend you carry out a rapid check for any deterioration that
may have occurred during transportation. If any deterioration is found,
immediately indicate this in due form to the carrier.
In the case of return of goods, use the original packaging and state the reasons
for return in a note enclosed with the apparatus.
Replacing the
batteries
The battery power level is measured by setting the switch to the BATT.CHECK
position.
-if the needle is deflected to the BAT.OK part of the scale, the battery level is
sufficient to carry out measurements,
-if however the needle is deflected to the BAT.LOW part of the scale, it is
necessary to replace the power supply batteries:
■
Disconnect all measurement cables and switch the instrument off (OFF
position).
■
Using a screwdriver, remove the 2 screws from the battery compartment cover
(on the underside of the instrument)
■
Put new batteries in place: 8 x 1.5 V batteries (AA or equivalent).
■
Replace the battery compartment cover.
■
Replace the 2 battery compartment cover screws.
Replacing a fuse There is a fuse fitted in the battery compartment of the apparatus.
To replace it with an equivalent fuse (1 A / 250 V 0.2
Ω
),
■
■ ■
■
switch the instrument OFF
■
remove the 2 screws from the battery compartment cover on the underside
of the instrument,
■
the fuse is on the right-hand side, under a plastic cap; replace the defective
fuse with an equivalent new fuse,
■ ■ ■ ■
replace the plastic cap, close the battery compartment cover, and put the
screws back in place.
To avoid electric shock or damage to your tester, do not allow water to
come into contact with the inside of the tester.
