4.4 Checking the discharge unit
Periodic checking of the discharge unit is for the purpose of safety. It should be performed before
placing the instrument into operation in order to avoid influence on the resistance measurement
caused by residual charges in the surge capacitors and temperature
increase in the resistors.

with instrument switched off, connect ohmmeter to the open terminals of the connection
line

measure resistance between terminals
The resistance value should be approx. 16,5 kOhm. At deviations of more than 20%, the
instrument has to be serviced only by an instructed service technician before putting it into
operation (see safety rules).
4.5 Replacing high voltage connecting lead

Observe safety precautions according to chapter „Safety precautions before opening the
surve voltage generator“. Before removing the protection cover please take care:

The mains cable needs to be disconnected at the instrument

The instrument must have been switched off for minimum 20 minutes

The high voltage connection to the test sample needs to be grounded as close as possible
to the instrument, and short circuited

Loosen mounting screws (29) of protective hood.

Remove protective hood.

Uncrew knurled nut (22) of H.V. connection.

Remove washer and cable lug.

Connect to earth and short out new H.V. connection cable on the side of the instrument.

First install station earth (blue) on instrument side and tighten knurled nut (23).

Subsequently, install H.V. connection and tighten knurled nut (22).
Use only the original BAUR H.V. connecting lead suitable for the
particular instrument.
When replacing parts, check if the accessible mounting screws for the
electrode support (25) are tightened. If necessary, clean inside of the spark
gap and the inside surface of the protective hood using a dry and fluff-
free cloth.

Put on protective hood (28) again.

Screw in all mounting screws (29).
