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.

Usage of the AS-probe adapter
To use the AS-probe adapter three connections have to be made.
At first the AS-active-probe is connected via the delivered adapter cable with
the connectors "±3V" and "IN" of the AS-probe adapter.

For power supply the input "PWR" has to be connected to a power supply
which delivers a DC voltage between 9 V and 36 V.
As third the output "OUT" has to be connected with the analog input of a
data acquisition system like e.g. a PLC.
The gain switch is set to the desired position (x5 or x50).
