  • Page 7: Description

    1 DESCRIPTION The Models MR417 and MR527 are clamp-on current probes that measure DC currents up to 1400A, AC currents up to 1000A (1400A peak), and combined AC+DC currents without opening the circuit in which the currents flow. They indicate the shape and amplitude of the current measured in the form of a voltage.

    In this case, ensure the clamp is not on a conductor and that its jaws are correctly closed. Then press DC Zero again. Alternately, turn the clamp OFF and then back ON. The previous zero adjustment will remain in effect. Current Probe Models MR417/MR527...

  • Page 12: Measurements

    Figure 4 (MR527 shown) 2.6.2 Converting to Current The MR417 and MR527 both provide two measurement ranges. The MR417 measures current up to 600A with 1mV of output corresponding to 1A, and current up to 60A with 10mV corresponding to 1A. The MR527 measures current up to 1400A with 1mV corresponding to 1A, and current up to 150A with 10mV corresponding to 1A.
