Description
A clamp meter is a meter used to measure the current of a running electrical circuit, and it can measure current under uninterrupted power conditions. The clamp meter is essentially composed of a current transformer, a clamp wrench and a rectifier type magnetoelectric system with reaction force instrument.
Instructions:
(1) Make mechanical zero adjustment before measuring
(2) Select the appropriate range, first select the large range, then select the small range or estimate the value on the nameplate.
(3) When the minimum range is used for measurement and the reading is not obvious, the wire to be measured can be wound several turns, the number of turns should be based on the number of turns in the center of the jaw, then the reading = indication value × range / full offset × turn number
(4) When measuring, the wire to be measured should be in the center of the jaws, and the jaws should be closed tightly to reduce errors.
(5) After the measurement is completed, place the transfer switch at the maximum range.
