Main Features of A621/A622 Low-Frequency General-Purpose AC/DC Probes:
A621——2000 Amp AC Current Probe / BNC
This industrial-grade clamp-on probe comes with a BNC connector and can be used with Adapter 1 with banana plugs, making it suitable for digital multimeters, TekMeter, and oscilloscopes. The A621 can measure AC currents from 100 mA to 2000 A peak over a frequency range of 5 Hz to 50 kHz. It provides an output of 1 mV, 10 mV, or 100 mV per amp of measurement.
A622——100 Amp AC/DC Current Probe / BNC
This "long-nose" clamp-on probe uses a Hall effect current sensor to provide voltage output for oscilloscopes. It has a BNC connector and can be used with shielded banana plug Adapter 1, making it also suitable for digital multimeters, TekMeter, and oscilloscopes. The A622 can measure AC/DC currents from 50 mA to 100 A peak over a frequency range from DC to 100 kHz. It provides an output of 10 mV or 100 mV per amp of measurement.
