Remarks

Using CT

1. Use combined CT and 5A (1A) meter if 10A is exceeded.
2. When circuit voltage of 600V is exceeded at 10A or below, use combined CT and 5A (1A) meter for insulation.

Extended Scale Meter

Use a double, triple or five-times extended scale meter-standard meter to measure the current flow of the electric motor class of starting current.
Usage example For a triple extended scale AVF-11M 0~100~(300)A(CT ratio 100A/5A)

Note 1) In the case of extended scale meters, the 70% point on the scale length represents the measurement range (upper limit value of the effective measurement range), and the section that exceeds 70% up to 100% is the extended scale section.
(Extended scale part intrinsic error: ±10% of indicated values)
Note 2) The red color extended scale lines are the points below for extended scale meters

Specifications

Scale Calibration Conducted via sine waves
Telemetering For direct feed type telemetering, you can reduce line loss if the second rated value uses a 1A CT combined with a 1A meter. (The rated value of 5A is 1/25.)
To further reduce loss, use an AC transducer combined with a DC meter.
