The Megger ICLAMP current probe is designed for measurements of AC currents up to 1000 A with a 1000:1 step-down ratio. The probe offers excellent accuracy (0.3% error at full range) and small phase shift (0.7° at full range) so it can be used for metering of power, energy and power quality applications.

ICLAMP can be used with the dedicated earth tester instruments DET3TC, DET4TC and DET4TCR and with the multifunction installation tester MFT1735 to perform the Attached Rod Technique (ART). ICLAMP can also be used in combination with a VCLAMP for stakeless testing using the DET4TC, DET4TCR and MFT1735.

With the MFT1730 and MFT1735 control switch in the clamp position the ICLAMP can be used to measure current in the range from 1 mA to 1000 A.
