5.4 Exchange of electronics
• Loosen the four screws with a screwdriver
and open the housing cover.
• Loosen the two screws and remove the old
electronics.
• Insert the new oscillator.
• Carry out an adjustment. The instruction is
given under "4.2 Switching point adjust-
ment“.
5.5 Shortening of the electrodes
Shortening of the electrode
Rod electrodes
Fully insulated electrodes have fixed dimen-
sions and must therefore not be modified in
their dimensions. Any modification will de-
stroy the instrument.
All partly insulated electrodes can be short-
ened. The measuring probes are compen-
sated to the appropriate electrode length with
the factory setting. If the probe is shortened
by more than 30 %, it should be recompen-
sated. Call our service department.
Cable electrodes
The cable electrodes VEGACAP 31, 33, 34
and 35 can be shortened afterwards.
Instructions for shortening VEGACAP 31,
33 and 34
• Loosen the two set screws on the gravity
weight (hexagon socket) and remove
them.
• Pull the cable out of the gravity weight.
• To avoid fraying the steel cable during
cutting, you must tin the cable approx.
5 cm around the cutting position with a
soldering iron or blowtorch, or tightly bind
the cable together with a wire.
• Shorten the electrode cable with a metal
cutting saw or a cutting-off wheel. Insulated
cable must not be tinned since it cannot
come unravelled.
• Insert the cable into the hole of the gravity
weight (insulated cables: with the insula-
tion) and clamp the cable with the two set
screws. With insulated electrode cable, the
tips of the two set screws must penetrate
the cable insulation to ensure contact of the
gravity weight with the metal cable.
• Carry out an adjustment. The instructions
can be found under "4.1 Adjustment“.
If the cable is shortened considerably, it may
not be possible to carry out an adjustment
with the measuring probe. In this case, the
measuring probe must be recompensated.
Note the serial number of the measuring
probe and call one of our technicians.
