Page 7: Description
1 DESCRIPTION The Models MR525 and MR526 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. -

Arrow indicating current flow direction DC Zero button OL (overload) and ON indicators. ON is green when Auto Standby is enabled, yellow when it disabled. Slide switch (2-position for MR525, 3-position for MR526) USB port Trigger Hand guard Mobile jaw... -
Page 9: Operation
When operating on external power, the Auto Standby feature is disabled. The color of the ON indicator shows whether automatic standby is enabled (green) or disabled (yellow). Current Probe Models MR525/526... -
Page 10: Turning On The Instrument
2.3 Turning ON the Instrument Turn on the clamp by pushing the slide switch to the 1mV/A or 10mV/A setting: 1mV/A corresponds to the 1400A range (MR525 and MR526) 10mV/A corresponds to the 150A range (MR526) The green ON indicator should light up: If indicator blinks, less than 4 hours of battery life remains ... -
Page 11: Measurements
Figure 3 (MR526 shown) 2.6.2 Converting to Current The MR525 and MR526 can both measure current up to 1400A, with 1mV of output corresponding to 1A. In addition, the MR526 provides a second measurement range up to 150A, with 10mV corresponding to 1A. -
