International Electrical Symbols

[Double Insulation Symbol]: This symbol signifies that the instrument is protected by double or reinforced insulation. Use only specified replacement parts when servicing the instrument.

[Warning Symbol]: This symbol on the instrument indicates a WARNING and that the operator must refer to the user manual for instructions before operating the instrument. In this manual, the symbol preceding instructions indicates that if the instructions are not followed, bodily injury, installation/sample and product damage may result.

[Electric Shock Symbol]: Risk of electric shock. The voltage at the parts marked with this symbol may be dangerous.

[Type A Current Sensor Symbol]: This is a type A current sensor. This symbol signifies that application around and removal from HAZARDOUS LIVE conductors is permitted.

Measurement Categories

CAT IV: For measurements performed at the primary electrical supply (<1000V) such as on primary overcurrent protection devices, ripple control units, or meters.
CAT III: For measurements performed in the building installation at the distribution level such as on hardwired equipment in fixed installation and circuit breakers.
CAT II: For measurements performed on circuits directly connected to the electrical distribution system. Examples are measurements on household appliances or portable tools.

Product Features

Description

The AC/DC Current Probe Model MR6292 is an accessory for the AEMC® 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.

The Model MR6292 uses Hall effect technology. All electronics are self-contained in the handle. The output of the probe is 10mV/A. No battery is required; the probe operates via voltage provided by the Model 6292. The probe has a proportional mV output for direct reading on the Model 6292.

Operation

The Model MR6292 probe is used in conjunction with the Micro-Ohmmeter Model 6292 to perform measurements in BSG (both sides grounded) mode. For additional information about using the Micro-Ohmmeter Model 6292, refer to the user manual on the USB Stick that ships with the instrument.

Making Measurements

Plug the probe into the Model 6292.
Turn the power to the Model 6292 ON.
The green LED on the Model MR6292 should be lit. If the LED does not come ON or goes OFF after a few minutes, check to ensure that the Model 6292 instrument is still powered ON, and that the Model MR6292 is securely plugged into the instrument's socket.
Set up a test on the Micro-ohmmeter Model 6292, as instructed by the instrument's user manual (located on the USB stick).
Clamp the probe on the ground conductor to be tested, then start the test. The Model 6292 will display the measured ground conductor current as the "Ig" reading on the instrument's LCD display panel.

Example display output:

R=100.0uΩ
It=142A
DURATION: 015/060s
10/20/13 03:25 PM
Ig=8.0A

In the preceding example, the Ig measurement provided by the MR6292 probe is 8.0A.

Operation Examples

Conductor carrying 25ADC in the direction of the arrow. Model 6292 displays Ig = 25A.

Maintenance

WARNING:

For maintenance use only specified replacement parts.
To avoid electrical shock, do not attempt to perform any servicing unless you are qualified to do so.
To avoid electrical shock and/or damage to the instrument, do not get water or other foreign agents into the case. Turn the current probe OFF and disconnect the unit from all the circuits before opening the case.

Cleaning

Clean the body of the clamp with a cloth lightly moistened with soapy water.
Wipe clean with a cloth moistened with clean water and dry.
Do not use solvent.

Repair and Calibration

To ensure that the Model MR6292 meets factory specifications, it is recommended to schedule it back to the factory Service Center at one-year intervals for recalibration, or as required by other standards or internal procedures.

For instrument repair and calibration:

Contact the Service Center for a Customer Service Authorization Number (CSA#). This ensures prompt tracking and processing of the instrument upon arrival. Write the CSA# on the outside of the shipping container. If returning for calibration, specify if a standard calibration or a calibration traceable to N.I.S.T. (includes calibration certificate plus recorded calibration data) is required.
