User Manual
DESCRIPTION
The The MN114 (Catalog #2110.71) is a high accuracy voltage output current probe for
tight areas such as crowded wiring. Extends DMM AC measurements to 10 Aac. The Model
MN114 offers 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 250 V. 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 symbol signifies that this is a type A current sensor and that application near and
removal from HAZARDOUS LIVE conductors is permitted.
This symbol signifies a voltage limiting circuit.
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.
