VOLTCRAFT GT-6000 Bedienungsanleitung Seite 71

Voltage measurement at external earthed socket
Measurement range
5 V - 270 V/AC
Displays:
Voltage between the external conductor (L) and the neutral conductor (N)
Voltage between the external conductor (L) and the protective conductor (PE)
Voltage between the neutral conductor (N) and the protective conductor (PE)
Limit values in accordance with DIN VDE 0701-0702 and ÖVE/ÖNORM E 8701-1
The limit values in bold are stored in the GT-6000

Never exceed the maximum permitted input values. Never touch circuits or parts of circuits when
they may contain voltages greater than 33 V/ACrms or 70 V/DC! Danger of death!
