Measurement preparations
The body voltage caused by electrical alternating fields of the power
supply (capacitive body coupling voltage) is basically measured bet-
ween the person located in the field and ground.
The approx. 3 m long grounding line is therefore provided with a mo-
dified grounding type plug, which connects the measuring device
with ground, via the protective ground conductor of the power supply,
on insertion into a plug socket.
The banana plug of the grounding line is inserted into a socket above
on the measuring device

The approx. 50 cm long test cable is inserted into the other socket.
The other end of the test cable is connected with the hand-held elec-
trode

If you carry out measurements in the open air, e.g. near a high-volta-
ge line, you must ensure the grounding contact via a metal strip at
least 30 cm long, which is inserted into the ground.
The measuring device is now switched on using the push button

and is then ready for operation. The sound is switched on an off by
pushing

.
After switch on, the measuring range is „20000 mV“ (=20 Volt). This
means that you can measure a max. body voltage of 20 volt in this
range.
If a higher body voltage is present, the display

] In this
case, the measurement is far over the recommendations of building
biology.
However, the range „20000 mV“ is the correct range for measu-
rements in most cases.
