- Page 8 2. PRODUCT FEATURES 2.1 DESCRIPTION The Models MR525 and MR526 are clamp-on current probes that measure DC currents up to 1400 A, AC currents up to 1000 Arms (1400 Apeak), and combined AC+DC currents without opening the circuit. They indicate the shape and amplitude of the current measured in the form of a voltage.
