User Manual

DESCRIPTION

The Model MN103 (Catalog #1031.02) measures leakage current and low currents from
1 mA, and measures current on 5 A secondaries. This current probe provides AC current
measuring capabilities to instruments with mV inputs. The Model MN103 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 insu-
lation. 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.

DEFINITION OF MEASUREMENT CATEGORIES (CAT)

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