8.3 Measurement

Warning:
For reliable measurements the relative humidity must not exceed 60%.
Note
− To obtain proper measurements, earthing of the measuring instrument is essential.
− The buzzer sounds continuously, when a value higher than 330 volts is displayed
(overrange). Stop measurement in this case.
1 Earth the ion balance plate to remove any remaining static charge.
