The Model 428E Clip-on AC/DC Milliammeter measures current without the need for breaking the circuit. The probe can be clipped onto wires up to 0.160” diameter; system accuracy is not affected by wire size.

- 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.
