AC Current Probe

Model MN213

User Manual

DESCRIPTION

The AEMC®Instruments Model MN213 (Cat. #2115.75) is a small, compact AC current

probe. Designed to meet the most stringent demands in industry and electrical contracting, it

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

up to 240 Arms which makes it a perfect tool for measurement with DMMs, recorders, power

and harmonic meters. The Model MN213 is compatible with any AC ammeter, multimeter, or

other current measurement instrument with an input impedance lower than 1 MΩ. To achieve

the stated accuracy, use the MN213 with an ammeter having an accuracy of 0.75% or better.

OPERATION

Please make sure that you have read and fully understand the WARNING section on page 1.

Making Measurements with the AC Current Probe Model MN213

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 with the arrow pointed toward the load. 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 reading = 0.159 A, the current

owing through the probe is 0.159 A x 1000 = 159 AAC)

For best accuracy, avoid if possible, the proximity of other conductors which may create noise.

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.

Contaminants cause air gaps between the jaws, increasing the phase shift between

primary and secondary. It is very critical for power measurement.

MAINTENANCE

Warning

For maintenance use only original factory replacement parts.

To avoid electrical shock, do not attempt to perform any servicing unless you are

qualied to do so.

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

foreign agents into 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, then gently clean with a soft oiled cloth.

REPAIR AND CALIBRATION

To ensure that your instrument meets factory specications, we recommend that it be sent

back to our factory Service Center at one-year intervals for recalibration or as required by

other standards or internal procedures.

For instrument repair and calibration:

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

Send an email to [email protected] requesting a CSA#, you will be provided a CSA Form

and other required paperwork along with the next steps to complete the request. Then

return the instrument along with the signed CSA Form. 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. If the instrument is returned for calibration, we need

to know if you want a standard calibration or a calibration traceable to N.I.S.T. (includes

calibration certicate plus recorded calibration data).
