such as crowded wiring. It extends DMM AC measurements to 150A AC. The Model MN106
offers a 5ft lead with safety 4mm banana plug.

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: Potentially high voltages and currents may be present and may
pose a shock hazard.

• Read the Safety Specifications section prior to using the current probe. Never exceed the
maximum voltage ratings given.

• Safety is the responsibility of the operator.

• ALWAYS connect the current probe to the display device before clamping the probe onto the
sample being tested.

• ALWAYS inspect the instrument, probe, probe cable, and output terminals prior to use.
Replace any defective parts immediately.

• NEVER use the current probe on electrical conductors rated above 600V. Use extreme caution
when clamping around bare conductors or bus bars.

INTERNATIONAL ELECTRICAL SYMBOLS

This symbol signifies that the current probe is protected by double or reinforced insulation. Use
only factory specified replacement parts when servicing the instrument.

This symbol signifies CAUTION! and requests that the user refer to the user manual before
using the instrument.

This is a type A current sensor. This symbol signifies that application around and removal
from HAZARDOUS LIVE conductors is permitted.

RECEIVING YOUR SHIPMENT

Upon receiving your shipment, make sure that the contents are consistent with the packing list. Notify
your distributor of any missing items. If the equipment appears to be damaged, file a claim immediately
with the carrier and notify your distributor at once, giving a detailed description of any damage.

INSTRUMENT COMPATIBILITY

The probe is compatible with any ammeter, multimeter, or other current measuring instruments with an
input impedance of  5. To achieve the stated accuracy, use the probes with an ammeter having an
accuracy of 1% or better.

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 prov

ides 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 wa

ter 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.
