AC Current Probe

Model MN02

User Manual

DESCRIPTION

The Model MN02 (Cat. #2129.20) is a small, compact AC current probe and is designed

to meet the most stringent demands in industry and electrical contracting. This instrument

meets the latest safety and performance standards. The probe has a measurement range

up to 100 Arms which makes it a perfect tool for measurement with DMMs and recorders.

The Model MN02 is compatible with any AC ammeter, multimeter, or other current

measurement instrument with an input impedance lower than 10 Ω. To achieve the stated

accuracy, use the probe with an ammeter with an accuracy of 0.75 % or better.

WARNING

These safety warnings are provided to ensure the safety of personnel and proper operation of the

instrument.

• Read the instruction manual completely and follow all the safety information before attempting to use

or service this instrument.

• Use caution on any circuit: high voltages and currents may be present and may pose a shock hazard.

OPERATION

Please make sure that you have already read and fully understand the WARNING section

on page 1.

Making Measurements with the AC Current Probe Model MN02

• Connect the black lead of the current probe to “common” and the red lead to the

AC current input on your DMM or other current measuring instrument. Select the

appropriate current range (400 mAAC range). Clamp the probe around the conductor

to be tested. If the reading is less than 400 mA, select the lower range until you obtain

the best resolution. Read the value display on the DMM and multiply it by the probe

ratio (1000/1). If the reading = 0.098 A, the current owing through the probe is

0.098 A x 1000 = 98 AAC.

• For best accuracy, avoid taking measurements in the proximity of other conductors if

possible. The other conductors may create noise that will a󰀨ect the accuracy of the

measurement.

Tips for Making Precise Measurements

• When using a current probe with a meter, it is important to select the range that

provides the best resolution. Failure to do this may result in measurement errors.

• Make sure that probe jaw mating surfaces are free of dust and contamination. It is

critical for power measurement. Contaminants cause air gaps between the jaws,

which increases the phase shift between primary and secondary.

MAINTENANCE

Warning

• For maintenance, use only original replacement parts.

• To avoid electrical shock, do not attempt to perform any service on the device unless

you are qualied to do so.

• To avoid electrical shock and/or damage to the instrument, do not allow water or other

foreign agents to come into contact with the probe.

Cleaning

To ensure optimum performance, it is important to keep the probe jaw mating surfaces

clean at all times. Failure to do so may result in error in readings. To clean the probe jaws,

use very ne sand paper (ne 600) to avoid scratching the jaw, and then gently clean with a

soft, oiled cloth.

REPAIR AND CALIBRATION

You must contact our Service Center for a Customer Service Authorization number (CSA#).

This will ensure that, when your instrument arrives, it will be tracked and processed

promptly. Please write the CSA# on the outside of the shipping container.
