Remarks

When Using CT
1. Combine the meter with CT and the C-3 model 5A (1A)/10mA current transducer if 100A is exceeded.
2. When circuit voltage of 460V is exceeded at 100A or below, combine the meter with CT and the C-3 model 5A (1A)/10mA current transducer for insulation.
Note: The C-3 model current transducer is a dedicated accessory for the meter. The combined intrinsic error for the meter and the C-3 model current transducer is ±2.5%.

Frequency 
Indicate the frequency when measuring AC outside of commercial frequencies.
(Can be manufactured from approximately 30Hz to 10kHz)

Extended Scale Meter

Meters attached with double, triple or 5-times extended scale to use for measuring the current flow of electric motor-class of starting current can be manufactured.
(In this case, the M-2A model rectifier box is externally connected.)

Scale Calibration : Conducted via sine waves.

Note

1. Multi-scale meters can also be manufactured.
2. We also manufacture R.M.S.-Response models that minimize the impact of waveforms. The model names are SeCF-6, 8, 10 and 12N.
(The C-3 model current transducer and M-2A model rectifier box are externally connected.) (Additional price)
The scale is nonlinear, condensed near zero.
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 current transducer combined with a DC meter.
(For details on AC current transducers, see the dedicated catalog.)
