2. Technical Advice
2.8
AS-Adapter 3
One should be aware, that the probes and all outputs have a common
ground. Especially when using the brass version of AS-probes (AS-NTM,
AS-LTM) an isolation between probe and other parts of the measurement
setup can be necessary. It should be noted that the three adapter cables (X,
Y, Z) and the probes provide a connection between the GND and the cable
shield as well as the connector housing. Possibly an isolated installation of
the probe is necessary to prevent an unintended connection between
measuring GND and protective earth.
2.9
ESD
Electrostatic discharges (> 0.5 kV) to the sensor can damage it. Structural
safety measures would affect measurement accuracy due to loss of
sensitivity.
2.10
Minimum Operation Conditions (EMC)
Measurement results may vary up to 2 % in the presence of strong HF fields
(> 3 V/m).
2.11
Ground Connection / Earthing
It should be observed, that in the probe a connection between GND, plug
shield, plug case and cable shield is made. At bass probes, this is also
connected to GND. Possibly an isolated installation of the probe is
necessary to prevent an unintended connection between measuring GND
and protective earth.
