OPERATION
Making Measurements with the AC Current Probe Model MN106:

• Connect the black lead of the current probe to “common” and the red lead to the AC current range on
your DMM or other current measuring instrument. The MN106 has a ratio of 1000:1. This means that for
100A AC in a conductor around which the probe is clamped, 100mA AC will come out of the probe leads
to your DMM or instrument. The output is 1mA AC/A AC. 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 first and 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).

Meter Reading 5mA 20mA 100mA
Measured Value 5000mA = 5A 20000mA = 20A 100000mA = 100A

• 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. 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).
