Inserting / changing the battery
Before the first taking into operation or when LOW-BATTERY
appears in the display, you have to insert a new 9 V block battery
(preferably Alkaline). Proceed as follows:
Push the grooved area of the battery case lid on the backside of the
cable tester and push the lid open to the side. Now remove the bat-
tery clip, respectively the used battery with clip. When connecting
the new 9V block battery pay attention to the right position of the
battery poles at the clip. A wrong poling of the battery can lead to
the destruction of the device and a short circuit of the battery con-
tacts can lead to the destruction of the battery! Now insert the bat-
tery with clip into the battery case and close the lid. Please take care
that the battery connection cables are not squeezed. Under no cir-
cumstances operate the cable tester when it is open or with anoth-
er voltage supply.
Attention!
Do not leave used batteries in the measuring device,
because even leak protected batteries can corrode.
Because of that chemicals maybe set free Which are
hazardous to your health or damage the device.
Remove the batteries from the battery case if you do not
use the cable tester for a longer period of time. Don’t
ever try to recharge batteries and do not throw them into
the fire. There is the acute danger of an explosion.

Attention!
The testing of cables with the cable tester is only
permitted when the cable is free of voltage.
Before every measurement it has to be tested that
the cable which is to be measured is free of voltage
(danger to life).
