Making Measurements with the AC Current Probe Model MN02
•
Connect the black lead of the current probe to "common" and the red lead to the
AC current input on your DMM or other current measuring instrument. Select the
appropriate current range (400 mA
to be tested. If the reading is less than 400 mA, select the lower range until you obtain
the best resolution. Read the value display on the DMM and multiply it by the probe
ratio (1000/1). If the reading = 0.098 A, the current flowing through the probe is
0.098 A x 1000 = 98 A
•
For best accuracy, avoid taking measurements in the proximity of other conductors if
possible. The other conductors may create noise that will affect the accuracy of the
measurement.
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. It is
critical for power measurement. Contaminants cause air gaps between the jaws,
which increases the phase shift between primary and secondary.
