AC Current Probe
Models MN352 and MN353
User Manual
DESCRIPTION
The Models MN352 and MN353 (Catalog #2116.26 and #2116.27) are the latest in compact AC
current probes. Designed to meet the most stringent demands in industry and electrical contracting,
they also meet the latest safety and performance standards. This probe has a measurement range
up to 240 Arms which make them perfect tools for measurements with DMMs, recorders, power and
harmonic meters. The Models MN352 and MN353 are compatible with any AC voltmeter, multimeter,
or other voltage measurement instrument that is capable of displaying 10 mV of output per amp of
measured current, an accuracy of 0.75 % or better and an input impedance of ≥ 1 MΩ.
WARNING
The safety warnings are provided to ensure the safety of personnel and proper operation of the
instrument. Read the instruction completely.
• Use caution on any circuit: potentially high voltages and currents may be present and may pose
a shock hazard.
• Do not use the probe if damaged. Always connect the current probe to the measuring device
before it is connected around the conductor.
• Do not use on non-insulated conductor with a potential to ground greater than 600 V CAT III
pollution 2. Use extreme caution when clamping around bare conductors or bus bars.
• Before each use, inspect the probe; look for cracks in housing or output cable insulation.
• Do not use clamp in wet environment or in locations that hazardous gases exist.
• Do not use the probe anywhere beyond the tactile barrier.
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.
