For industry use (for DC and AC measurement)

All the Functions You Need for Measurement at DC or 1Hz and Up

  • Choice of three sensors (Example combinations)
  • Measure up to 100 A, 200 A, or 2000 A rated current
  • Correct measurement for inverter current with AC+DC mode and True RMS rectification
  • Choice of output (Simultaneous output) Effective value, waveform, frequency, and integral value output
  • Choice of response time with three steps
  • Model 3290-10 only with integral current measurement, operating time rate measurement.

Basic specifications (Accuracy guaranteed for 1 year, or opening and closing of the clamp sensor 10,000 times)
