Checking the discharge unit
Replacing high voltage connecting lead
☞
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 high voltage connecting lead
•
measure resistance between terminals
The resistance value should be approx. 68 k
Ohm
. 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).
Replacing the high voltage connecting lead may be only performed
by instructed service personnel (see safety rules).
