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.Together with an oscilloscope, this isolated current transformer with its 2 measuring ranges can be used to represent peak currents up to 10 A DC with a bandwidth of up to 1400 kHz.The current transformer has a simplified zero adjustment ZeroDC and a selectable switchover to standby mode.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.
