    1. INTRODUCTION Thank you for purchasing the Current Probe Model MR417 or MR527. For best results from your instrument and for your safety, please read the following operating instructions carefully and comply with the precautions for use. This instrument is compliant with the IEC 61010-2-032 safety standards for voltages of 300V in measurement category IV or 600V in category III.

  • Page 6: Precautions For Use

    1.1 PRECAUTIONS FOR USE These instructions are intended to ensure the safety of users and proper operation of the instrument. Failure to observe these safety instructions may result in electric shock, fire, explosion, and desctruction of the instrument and/or installations. ■...

  • Page 7: Receiving Your Shipment

    1.2 RECEIVING YOUR SHIPMENT Upon receiving your shipment, make sure that the contents are consistent with the packing list. Notify your distributor of any missing items. It the equipment appears to be damaged, file a claim immediately with the carrier and notify the distributor at once, giving a detailed description of any damage.

  • Page 8: Description

    2. DESCRIPTION The Models MR417 and MR527 are clamp-on current probes that measure DC currents up to 1400A, AC currents up to 1000Arms (1400A 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.

  • Page 11: Operation

    3. OPERATION 3.1 BATTERY INSTALLATION Before changing the battery, set the switch to OFF and remove the clamp from the circuit being measured. Using a screwdriver, remove the battery compartment cover (1) from the back of the housing (see Figure 3). Connect the battery to the snap-on connector (2), observing polarity.

  • Page 12: Turning The Instrument On

    3.3 TURNING THE INSTRUMENT ON To turn the clamp on, push the slide switch to the 1mV/A or 10mV/A setting: MR417 ■ 1mV/A corresponds to the 600A range. 10mV/A corresponds to the 60A range. ■ MR527 1mV/A corresponds to the 1400A range. 10mV/A corresponds to the 150A range.

    3.6 MEASUREMENTS 3.6.1 Making a Measurement After adjusting the DC Zero: 1. Press the clamp trigger to open the jaws. 2. Clamp the jaws around the conductor to be measured. Use the centering marks on the jaws to position the clamp around the conductor. If the measurement is for a power calculation, ensure the arrow on the clamp jaws (see Figures 1 and 2) points in the right direction of the current flow: source...
