ATTENTION
The insulation resistance is crucial for piezoelectric transducers; it
should be greater than 10
plug connections have to be kept thoroughly clean. A positive or
negative signal drift of the nominal (rated) output signal indicates
insufficient insulation resistance. The plug connection contacts
should then be cleaned with a clean, lint‐free cloth and a cleaning
agent (petroleum ether, isopropanol).
ATTENTION
Protect the transducer plug and the transducer connection
socket of the charge amplifier against pollution and under no
circumstances touch the connectors (plug face) with your
hand. The supplied cover should always be in place when the
connection is not in use.
Use only the connection cable included in the scope of supply.
Once mounted, it should remain connected to the transducer, if possible.

3.1 Ambient temperature

The temperature has little effect on the output signal. To obtain optimum mea­
surement results, the nominal (rated) temperature range must be observed.
Temperature‐related measurement errors are caused by heating on one side
(e.g. radiant heat) or by cooling. A radiation shield and all‐round thermal in­
sulation produce noticeable improvements, but must not be allowed to form a
force shunt.
