As soon as one of the three connection cables has been connected to a low voltage
phase with sufficient supply voltage (100 V ... 480 V), the NIM 1000 automatically turns
on.
After the short switching on process, the system waits for confirmation from the user that
the electrical connection has been finished.
The corresponding dialogue window can be shut by a quick push of the rotary
encoder
, following which the three phase voltages are measured (audible phase
relay switching).
After switching on, the following information on the current status of the system is shown
on the left side of the display:
Power on
System status
Set measuring current
Network voltage and frequency
currently measured
Selected measuring mode (number of
measurements or measurement
duration) and selected operating
mode
Connected phases which are taken
into account in a measurement in
3-conductor mode.
