User Manual
DESCRIPTION
The MN01 (Cat. #2129.17) is small, compact AC current probe. Designed to meet the most stringent
demands in industry and electrical contracting, they also meet the latest safety and performance
standards. The probe has a measurement range up to 150Arms which makes it a perfect tool for
measurement with DMMs, recorders. The Model MN01 is compatible with any AC ammeter, multimeter,
or other current measurement instrument with an input impedance lower than 10 . To achieve the
stated accuracy, use the probe with an ammeter having an accuracy of 0.75% or better.
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 in overvoltage
category III (CAT III). 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.

DEFINITION OF MEASUREMENT CATEGORIES
CAT II: For measurements performed on circuits directly connected to the electrical distribution system.
Examples are measurements on household appliances or portable tools.
CAT III: For measurements performed in the building installation at the distribution level such as on
hardwired equipment in fixed installation and circuit breakers.
CAT IV: For measurements performed at the primary electrical supply (<1000V) such as on primary
overcurrent protection devices, ripple control units, or meters.
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.

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 MN01
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. 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
