How a Clamp Meter Reads
1. Select gear and range. Turn the meter switch to the DC current "mA" position, and select the correct range according to the measured current. If the current is not known, in order to prevent the current from being too large and exceeding the range, you can first place the DC current at the highest gear for testing. If the range is too large, then reduce the range until the range is appropriate.
2. Connect the circuit in series. When the multimeter measures current, the test leads must be connected to the current in series, and the red test lead is connected to the high potential end of the circuit, and the black test lead is connected to the low potential end of the current.
3. Reading method:
(1) Correctly select the scale line for reading.
(2) Converted current value: Current value = the number of scales pointed by the pointer × the size of the range / the maximum value of the selected scale.
