Clamp ammeter reading
1. Select the gear and range. Turn the meter switch to the DC current "mA" position, and select the range correctly according to the size of the current being measured. When the magnitude of the current is not known, in order to prevent the current from being too large and exceeding the measurement range, the test can be performed at the highest DC current level first. If the measurement range is too large, reduce the measurement range until the measurement range is appropriate.
2. Connect in series to the circuit. When measuring current with a multimeter, the test leads must be connected in series with the current, 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 mark for reading.
(2) Convert current value: Current value = number of scales pointed by the pointer × range size/maximum value of the selected scale.
