- Direct Measurement Type:

+ AC A: 1, 3, 5, 10, 15, 20A

+ DC mA: 1, 1.5, 2, 3, 5, 7.5, 10, 15, 20, 30A

+ AC V: 10, 50, 75, 100V

+ DC V: 10, 30, 50, 75, 100V

- Indirect Measurement Type:

+ AC A ( For connection current transformer (CT)) : 10-3000A

+ AC V ( For connection potential transformer (PT)): 300V-45kV

+ DC A ( For connection to shunt): 1, 7.5, 10, 15, 20A

For ranges higher than 20A DC, use external shunt with a 50mV DC Ammeter.

For ranges higher than 300V DC, use external Volt Divider with a 1mA Voltmeter.

For ranges higher than 5A AC, use external Current Transformer with a 5A AC Ammeter.

For ranges higher than 600V AC, use external Potential Transformer with a 150V AC Voltmeter.
