The PAC range includes clamp meters that use the Hall effect to measure AC and DC currents.Two forms are offered to allow cables with a diameter of 39 mm or 2 x 25.4 mm and small busbars to be enclosed.The range includes the PAC1x pliers and the PAC2x pliers for higher currents.An improved measurement resolution and accuracy is achieved through the 2 measuring ranges and the simplified zero adjustment ZeroDC__LW_AT__. The switch to standby mode can be selected.Thanks to a micro USB socket (type B / 5V DC) these new models can now be supplied with power via an external standard source. In the event of a power failure, an internal 9V battery supplies the power.This text is machine translated.
