User Manual

DESCRIPTION

The MN09 (Catalog #2129.21) is the latest in compact AC Current probes. 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 150Arms which makes it the perfect tool for
measurement with DMMs and recorders without an AC range. The Model MN09 is compatible with any
DC voltmeter, multimeter, or other voltage measurement instrument that is capable of displaying 100mV
of output per amp of measured current, voltmeter accuracy 0.75% or better and an input impe
50k

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 600V 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

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