1. INTRODUCTION
Warning
These safety warnings are provided to ensure the safety of personnel
and proper operation of the instrument.
• Read this instruction manual completely and follow all the safety
information before attempting to use or service this instrument.
• Use caution on any circuit: Potentially high voltages and currents
may be present and may pose a shock hazard.
MR6292. Never exceed the maximum working voltage ratings given.
• Safety is the responsibility of the operator!
• Never open the back of the instrument while connected to any circuit
or input.
• ALWAYS connect the Model MR6292 to the Micro-Ohmmeter Model
6292 instrument before clamping the probe onto the sample under test.
• Always inspect the probe and lead prior to use. Replace any defec-
tive parts immediately.
• NEVER use the Model MR6292 on electrical conductors rated above
600 V.
1.1 INTERNATIONAL ELECTRICAL SYMBOLS
Thank you for purchasing an AEMC®Instruments AC/DC Current Probe Model

1.2 DEFINITION OF MEASUREMENT CATEGORIES (CAT)
CAT IV corresponds to measurements performed at the primary electrical
supply (< 1000 V).
Example: primary overcurrent protection devices, ripple control units, and
meters.
CAT III corresponds to measurements performed in the building installation
at the distribution level.
Example: hardwired equipment in xed installation and circuit breakers.
CAT II corresponds to measurements performed on circuits directly
connected to the electrical distribution system.
Example: measurements on household appliances and portable tools.
1.3 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. If the
and notify your distributor at once with a detailed description of any damage.
Save the damaged packing container to substantiate your claim.

2. PRODUCT FEATURES
2.1 DESCRIPTION
The AC/DC Current Probe Model MR6292 is an accessory for the AEMC®
Instruments Micro-Ohmmeter Model 6292. The Model MR6292 probe is
required for using the Model 6292 to take measurements in BSG (both sides
grounded) mode.
The probe is designed to meet the latest safety and performance standards.
The probe’s hook-shaped jaws enable you to “pry” into or “hook” onto cables
(it will accept 2 x 500 MCM) or small bus bars.
contained in the handle. The output of the probe is 10 mV/A. No battery is
The probe has a proportional mV output for direct reading on the Model
6292.
