The Megger DH3 duplex test lead with helical spring-point duplex hand spike is used with Megger DLRO10HD, DLRO10, DLRO10X, and BT51 digital microhmmeters. This duplex test lead measures both current and resistance when taking four-wire resistance measurements, which are more accurate than two-wire resistance measurements and allow low resistance values to be detected. The helical spring-point hand spikes compress and rotate to ensure good contact. There is a 10mm between the current and potential probe tips on the duplex hand spikes.
