DC/AC Voltage
400 mV DC only 0.1 mV ( 0.5 % + 2d )Overload AC/DC 600 V.
4 V 0.001V DCV: Overload AC/DC 600 V.
40 V 0.01V ( 1 % + 2d )Overload AC/DC 600 V.
400 V 0.1 V ACV:
600 V 1 V ( 1.2 % + 5d )
DC /AC 400 A 0.1 A ( 2 % + 5 d )

DC/AC Current :
400 A AC A 0.1 A ( 2 % + 5 d )
0.5 to 400A Overload AC/DC 600 A
