8.10 Automatic test
If the ISOMETER® measures in ISOnet mode, the "ON" LED flashes and the measurement
progress bar
in the lower right corner pulses.
First, the ISOMETER® performs an automatic test. During the test, the connections to the
IT system and to earth are tested. Afterwards, the ISOMETER® performs an initial measure-
ment and records all measured values in the device.
The ISOMETER® then measures during one measuring cycle before passing on the author-
isation for insulation measurement to the ISOMETER® with the next higher address.
