In case of difficult installation conditions, for example in a socket, the
probe can be adapted respectively with a rod extension.
Let the probe length determine automatically by the instrument to
compensate the resulting running time changes.
You can find further information in the supplementary instructions of
the rod extension.
To compensate the normal bias voltage loss due to the seal materials,
you have to use also disc springs in addition to the flange screws for
fastening PTFE plated flanges.
The flange screws of VEGAFLEX 83 must always be tightened with
a torque of approx. 60 Nm (44 lbf ft) so that the PTFE washer seals
reliably.
