Maintenance, Troubleshooting, Disposal
• Check if the current output has been overloaded.
– Measure the voltage across the current output terminals and
measure the output current. Calculate the resulting load.
The load must not exceed 600 ohms.
• Check if the voltage output has been overloaded.
– Measure the current in the voltage output loop and measure the
output voltage. The resulting load must not fall below 1000 ohms.
• Check if there is an overdrive of the input signal.
– Negative overdrive results in a large negative output signal.
– Positive overdrive results in a large positive output signal.
• Check the output.
– Measure with a multimeter, for example, to check whether
the output signal matches the input signal and the selected
measuring range.
Storage
Observe the specifications for storage temperature and relative
humidity given in the Specifications chapter.
Disposal
Observe the applicable local or national regulations concerning the
disposal of "waste electrical and electronic equipment".
You can give the high voltage transducer to a certified waste manage-
ment company for proper disposal.
