1. How to measure the current with a clamp meter
Before using the clamp ammeter, you should read the manual carefully to find out whether it is an AC or AC/DC clamp meter, and choose the right measurement gear.
Moreover, the magnitude of the measured current should be estimated before the clamp meter measurement, and then decide which range to use. If it is impossible to estimate, you can use the maximum range first and then change it to a smaller one for accurate reading. Do not use small current gear to measure large current to prevent damage to the meter.
Steps for measuring current with clamp meter:
(1) Before measuring the line to be tested, the data of the clamp meter should be zeroed to prevent errors in subsequent measurements.
(2) After determining the voltage of the line to be measured, select the appropriate range.
(3) Press the wrench on the side of the clamp meter to open the jaws, place the circuit to be tested in the center of the jaws, and close the jaws.
(4) Get the data.
(5) After the measurement is completed, adjust the range adjustment knob to the maximum range to prevent accidental overcurrent in the next use.
