3.10 AC Current Probe MiniFlex
When installing probes, face the arrow on the probe in the direction of
the load.
Nominal Range: 1000A
Measurement Range: 10A to 1000A
Currents below 10A will be displayed as zero with this probe.
Probe Output Signal: 47µV
NOTE: Output is proportional to the amplitude and frequency of the measured current.
Sensor: Length = 10" (250mm); Ø = 2.75" (70mm)
