AEMC instruments MN106 User Manual

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 100 A in a conductor around which the probe is clamped, 100 mA
AC
leads to your DMM or instrument. The output is 1 mA
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, 59 mA reading: 59 x 1000 = 59,000 mA or 59 A).
Meter Reading 5 mA
Measured Value 5000 mA = 5A
• 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.

User Manual
DESCRIPTION
The Model MN106 (Catalog #1031.17) is a high accuracy current output current probes for tight areas
such as crowded wiring. It extends DMM AC measurements to 150 A
5 ft lead with safety 4 mm 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.
