AC Current Probe
Model MN01
User Manual
DESCRIPTION
The AEMC Instruments Model MN01 (Cat. #2129.17) is a 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 150 A
RMS
recorders. The Model MN01 is compatible with any AC ammeter, multimeter, or other
current measurement instrument with an input impedance lower than 10 Ω. 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.
ƒ Read the instruction manual completely and follow all the safety information before attempting to
use or service this instrument.
ƒ Use caution on any circuit: high voltages and currents may be present and may pose a shock hazard.
ƒ Read the Safety Specifications section prior to using the current probe. Never exceed the
maximum voltage ratings given.
ƒ Safety is the responsibility of the operator.
ƒ ALWAYS connect the current probe to the display device before clamping the probe onto the
sample being tested.
ƒ ALWAYS inspect the instrument, probe, probe cable, and output terminals prior to use. Replace
any defective parts immediately.
ƒ NEVER use the current probe on electrical conductors rated above 600 V in overvoltage CAT III.
Use extreme caution when clamping around bare conductors or bus bars.
INTERNATIONAL ELECTRICAL SYMBOLS
Signifies that the instrument is protected by double or reinforced insulation.
CAUTION - Risk of Danger! Indicates a WARNING. Whenever this symbol is present,
the operator must refer to the user manual before operation.
Application or withdrawal authorized on conductors carrying dangerous voltages. Type
A current sensor as per IEC 61010-2-032.

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