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.
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.

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
qualied 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 specications, 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.
