Making Measurements with the AC Current Probe Models SR701/SR740
•
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 (2 A
arrow pointed toward the load. If the reading is less than 200 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 reading = 0.659 A, the current flowing through the probe is
0.659 A x 1000 = 659 A
•
For best accuracy, avoid if possible, the proximity of other conductors which may create
noise.
