OPERATION
Please make sure that you have already read and fully understand the WARNING section on page 1.
Making Measurements with the AC Current Probe Model MN352/MN353.
Connect the black lead of the current probe to "common" and the red lead to the AC voltage input
•
on your DMM or other voltage-measuring instrument. The AC current probe has an output of 10
mV/A. This means that for 200 A
come out of the probe leads to your DMM or instrument. Select the range which corresponds to
the measured current. If the current magnitude is unknown, start with the highest range and work
down until the appropriate range and resolution are reached. Clamp the probe around the conduc-
tor. Take the reading on the meter and multiply it by 100 to obtain the measured current
(e.g, 160 mV reading = 160 x 100 = 16,000 mA or 16 A).
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 primary and secondary. It is very
critical for power measurement.
MAINTENANCE
Warning
■ For maintenance use only original factory replacement parts.
■ To avoid electrical shock, do not attempt to perform any servicing unless you are qualified to do so.
■ 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 jaws, use very fine sand
paper (fine 600) to avoid scratching the jaw, and then gently clean with a soft oiled cloth.
REPAIR AND CALIBRATION
You must contact our Service Center for a Customer Service Authorization number (CSA#). This will
ensure that when your instrument arrives, it will be tracked and processed promptly. Please write the
CSA# on the outside of the shipping container.
