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

When operating on external power, the Auto Standby feature is disabled. The color of the ON indicator shows whether the automatic standby is enabled (green) or disabled (yellow). AC/DC Current Probes MR417 & MR527...
■ Press the DC Zero button again. ■ In the event of failure, or if the clamp is switched off (selector set to OFF), it is the last adjustment of the DC Zero that is kept. AC/DC Current Probes MR417 & MR527...
Figure 4 (MR527 shown) 3.6.2 Converting to Current The MR417 and MR527 both provide two measurement ranges. The MR417 measures current up to 600 A with 1 mV of output corresponding to 1 A and measures current up to 60 A with 10 mV corresponding to 1 A. The MR527 measures current up to 1400 A with 1 mV corresponding to 1 A and measures current up to 150 A with 10 mV corresponding to 1 A.
