AC Current Probe
Models MN210 and MN211

User Manual

DESCRIPTION

The MN210/MN211 (Catalog #2115.72 and #2115.73) are the latest in compact AC Current probes.
Designed to meet the most stringent demands in industry and electrical contracting, they also meet the
latest safety and performance standards. The probes have a measurement range up to 240 Arms which
makes them perfect tools for measurement with DMMs, recorders, power and harmonic meters. The
Models MN210/MN211 are 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
MN210/MN211 with an ammeter having an accuracy of 0.75% or better.

Making Measurements with the AC Current Probe Models MN210/MN211

• 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 mA AC
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 flowing
through the probe is 0.159 A x 1000 = 159 A AC)

• 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. F

ailure 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. 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 certificate plus
recorded calibration data).
