User Manual
DESCRIPTION
The MN375 (Cat. #2115.41) is the late st in compact AC current pr obes. Designed to meet the most
stringent demands in industry and electrical contracting, it also meets the latest safety and performance
standards. This probe has a meas
voltmeter, multimeter, or other voltage measurement instru ment that has the fo llowing features: Range
and resolution capable of displaying 100mV of output per amp of measured current; Voltmeter accuracy
of 0.75% or better to take full advantage of the accuracy of the probe; Input impedance of  1M
WARNING
The safety w arnings are prov ided to ensure t he 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 w ith a potential to ground greater than 600V C AT 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 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 electrical supply (<1000V) such as on primary
overcurrent protection devices, ripple control units, or meters.
