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 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 (400mAAC
range). Clamp the probe around the conductor to be tested with the arrow pointed toward the load. If the
reading is less than 400mA, 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 = 0.159A, the current flowing
through the probe is 0.159A x 1000 = 159AAC)
• 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 qualified 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 fine sand paper (fine
600) to avoid scratching the jaw, 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.

AC Current Probe
Model MN213
User Manual
DESCRIPTION
The MN213 (Cat. #2115.75) is the latest in compact AC current probes. 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 240Arms 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. To achieve the stated accuracy, use the MN213 with an ammeter having an accuracy of
0.75% or better.
WARNING
The safety warnings are provided to ensure the safety of personnel and proper operation of the
instrument. Read the instruction completely.
• Use caution on any circuit: potentially high voltages and currents may be present and may pose
a shock hazard.
• Do not use the probe if damaged. Always connect the current probe to the measuring device
before it is connected around the conductor
• Do not use on non-insulated conductor with a potential to ground greater than 600V CAT III
pollution 2. Use extreme caution when clamping around bare conductors or bus bars.
• Before each use, inspect the probe; look for cracks in housing or output cable insulation.
• Do not use clamp in wet environment or in locations that hazardous gases exist.
• Do not use the probe anywhere beyond the tactile barrier.

OPERATION
Making Measurements with the AC Current Probe Model MN123
• Connect the black (S2) and red (S1) terminals to the 200mA range of your DMM or instrument. The
MN123 has a ratio of 1000:1. This means that for 100AAC in the conductor around which the probe is
clamped, 100mAAC will come out of the probe leads to your DMM or instrument. The output is 1mAAC
per Amp. Select the range on your DMM or instrument which best corresponds to the measured
current. If the magnitude is unknown, start with the highest range (200mAAC) then work down until the
appropriate range and resolution is reached. Clamp the probe around the conductor. Take the reading
on the meter and multiply it by 1000 to obtain the measured current (e.g., 59mA reading: 59 x 1000 =
59,000mA or 59A).
• 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.

• For maintenance use only original factory 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
