• 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.
•
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.

DEFINITION OF MEASUREMENT CATEGORIES (CAT)
CAT IV corresponds to measurements performed at the primary electrical supply (< 1000 V).
Example: primary overcurrent protection devices, ripple control units, and meters.
CAT III corresponds to measurements performed in the building installation at the
distribution level.
Example: hardwired equipment in xed installation and circuit breakers.
CAT II corresponds to measurements performed on circuits directly connected to the
electrical distribution system.
Example: measurements on household appliances and portable tools.

OPERATION
Making Measurements with the AC Current Probe Model MN114
■Connect the black (S2) and red (S1) terminals to the 2 V range of your DMM or
instrument. The MN114 has a ratio of 10:1. This means that for 10 A in the conductor
around which the probe is clamped, 1 V will come out of the probe leads to your
DMM or instrument. The output is 100 mV per Amp AC. Select the range on your
is unknown, start with the highest range (2 V) then work down until the appropriate
range and resolution is reached. Clamp the probe around the conductor. Take the
reading on the meter and multiply it by 10 to obtain the measured current.
Meter Reading 10 mV 120 mV 1200 mV
Measured Value
■For best accuracy, avoid if possible, the proximity of other conductors which may
create noise.
Tips for Making Precise Measurements
■When using a current probe with a meter, it is important to select the range that provides
the best resolution. Failure to do this may result in measurement errors.
■Make sure that probe jaw mating surfaces are free of dust and contamination.
Contaminants cause air gaps between the jaws, increasing the phase shift between
MAINTENANCE
Warning
■For maintenance use only original factory replacement parts.
■To avoid electrical shock, do not attempt to perform any servicing unless you are
■To avoid electrical shock and/or damage to the instrument, do not allow water or other
foreign agents to come into contact with the probe.
Cleaning:
■To ensure optimum performance, it is important to keep the probe jaw mating surfaces
clean at all times. Failure to do so may result in error in readings. To clean the probe
clean with a soft oiled cloth.
