AC/DC Current Probes - 1146A Low-cost AC/DC Current Probe

The 1146A ac/dc current probe provides

accurate display and measurement of

currents from 100 mA to 100 Arms, dc to

100 kHz, without breaking into the circuit. A

battery level indicator and overload indica-

tor help ensure proper readings. It connects

directly to the scope through a 2-m coaxial

cable with an insulated BNC. This probe

works with any 1 MΩ input oscilloscope.

1146A 100 mA to 100 Arms, dc to 100 kHz probe.
