Ammeter - PCE-CM 3 with open forks - PCE Instruments
With open forks / Measurement of several electrical parameters
The open-fork ammeter clamp is used for quick and simple AC measurements. All you have to do is insert the open forks into the one in the wire. The tweezers are specially designed to measure alternating currents in electrical enclosures and in any circuit that does not need to be interrupted. The range current measurement ranges from 0 to 200 A. In addition to measuring current, you can also measure AC and DC voltages up to 600 V, resistances, capacitance and temperature. Measurement values are shown on the backlit LCD display.
Its compact dimensions and low weight, as well as its durable housing, are some of the features of this current clamp with open forks. All this makes the ammeter an ideal tool for any installer or maintenance technician
