We get questions on the Fluke I30 AC/DC Current Clamp on how to read the output on a multimeter.
The Datasheet and Instruction sheet indicate the Output Sensitivity is 100mV/Amp
To use this device you would turn it to the DC Voltage setting on your multimeter and whatever number you get in Volts you would multiply that by 10 to get your measurement in Amps.
If you get 1 Volt output that would be 10 Amps, if you get 3 Volts output that would be 30 Amps. 300 milliVolts would be 3 amps.
This also applies to the I30S which is read on an Oscilloscope.
