Three full-scale pushbutton selectable ranges are available:

  • 100 mA
  • 1 Amp
  • 10 Amp

On the most sensitive range, currents down to 20 μA can be measured. A precision full-scale DC offset capability is included, enabling the measurement of small AC or DC current changes in the presence of a DC current up to 10A.

The system analog output is available at a front panel BNC connector, which enables measurement of signals over a wide bandwidth of 0 to 600 HZ in the DC mode and 20 to 600 Hz in the AC mode.

The Model 428E console features a bright 4 1/2 digit LED display and is compatible with Hewlett Packard 428 style clip-on current probes and magnetometer probes.
