AC Current Probe
Model MN213
User Manual
DESCRIPTION
The AEMC Instruments Model MN213 (Cat. #2115.75) is a small, compact AC current
®
probe. Designed to meet the most stringent demands in industry and electrical contracting, it
also meets the latest safety and performance standards. The probe has a measurement range
up to 240 Arms which makes it a perfect tool for measurement with DMMs, recorders, power
and harmonic meters. The Model MN213 is compatible with any AC ammeter, multimeter, or
other current measurement instrument with an input impedance lower than 1 MΩ. To achieve
the stated accuracy, use the MN213 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.
SYMBOLS AND DEFINITIONS
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

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.
