Model MN03
User Manual
DESCRIPTION
The MN03 (Cat. #2129.18) is small, compact AC current probe. Desi gned to meet the most stringent
demands in industry and electrical
standards. The probe has a measurem ent range up to 100Arms w
measurement with DMMs, recorders. The Model MN03 is compatible w ith any voltmeter, multimeter, or
other current measurement instrument w ith an input impedance greater than 1M
stated accuracy, use the probe with a voltmeter 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.
• 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 v oltages and cu rrents may be present and may
pose a shock hazard.
• Read the Safety Specifications section prior to
maximum voltage ratings given.
• Safety is the responsibility of the operator.
• ALWAYS connect the current probe to the di splay device before clam ping the probe onto the
sample being tested.
• ALWAYS inspect the instrument, probe, probe
Replace any defective parts immediately.
• NEVER use the current probe
category III (CAT III). 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 is a type A current sensor. This symbol signifies that application around and removal from
HAZARDOUS LIVE conductors is permitted.
DEFINITION OF MEASUREMENT CATEGORIES
CAT I: For measurements on circuits not
protected secondaries, signal level, and limited energy circuits.
CAT II: For measurements performed on circuits directly connected to the electrical distribution sy stem.
Examples are measurements on household appliances or portable tools.
CAT III: For measurements performed in the building inst
hardwired equipment in fixed installation and circuit breakers.
CAT IV: For measurements performed at the primary
overcurrent protection devices, ripple control units, or meters.
