CAUTION
The insulation resistance is crucial for piezoelectric transducers; it
should be no greater than 10
To obtain this value , all the plug connections have to be kept thoroughly
clean. A positive or negative signal drift of the output voltage indicates
insufficient insulation resistance. The plug connection contacts should then be
cleaned with a clean, lint-free cloth and a cleaning agent (petroleum benzine,
isopropanol).
For further information, see Chapter 11.
Use only the connection cable included in the scope of supply.
Once mounted, it should remain connected to the transducer, if possible.
4.1 Ambient temperature
The temperature has little effect on the output signal. To obtain optimum
measurement 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 (see chapter 11.4 "Thermal
influences").
4.2 Moisture and humidity
Moisture and humidity or a tropical climate are to be avoided. When the
connection cable is properly connected to a transducer/charge amplifier or the
protective caps are applied, the CMD600 charge amplifier has degree of
protection IP60 as per DIN EN 60529 (see chapter 11.4 "Thermal influences").
