NOTE
1) CT Type: There is an internal CT with CT setting. Above 5A (0-5A model)
or 1A (0-1A model) external CT is required.
2) Shunt Type: External Shunt (0-75mV DC) is required for measurement.
2000, 2500, 3000, 4000
3) Direct Type: Current is directly applied at the input terminal and the unit shows the
reading.
