The LED „ON“ blinks and the bar indicating the progress of measurement is pulsing,
if the ISOMETER® measures actively in the ISOnet mode.
The ISOMETER® performs an automatic test. During this test, the ISOMETER® checks the
connections to the IT system and earth. Afterwards, the ISOMETER® performs an initial
measurement and records all measured values (see page 29).
Hereafter, the ISOMETER® measures for one measuring cycle and then forwards the au-
thorisation for insulation measurement to the ISOMETER® with the next higher address.
