Making Measurements with the AC Current Probe Model MD304
•
Connect the black and red terminals to the Ampere AC range of your DMM or current
measuring instrument. Select the appropriate current range (10 A
probe around the conductor to be tested with the arrow pointed toward the load. Read the
value display on the DMM and multiply it by the probe ratio (100/1). (If reading = 4.59 A,
the current flowing through the probe is 4.59 A x 100 = 459 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.
