User Manual
DESCRIPTION
The MN115 (Catalog #2110.72) is a high accuracy voltage output current probe for tight areas such
as crowded wiring. Extends DMM AC measurements to 100 A AC. The Model MN115 offers a 5 ft.
lead with safety 4mm 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 600 V in overvoltage
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 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.
RECEIVING YOUR SHIPMENT

- Page 4 Making Measurements with the AC Current Probe Model MN115 • Connect the black (S2) and red (S1) terminals to the 2 V range of your DMM or instrument. The MN115 has a ratio of 100:1. This means that for 100 A AC in the conductor around which the probe is clamped, 1 V AC will come out of the probe leads to your DMM or instrument.
