Making Measurements with the AC Current Probe Model JM865A
■Connect the black and red terminals to the Ampere AC range of your DMM or current
measuring instrument. Select the appropriate current range. If the current magnitude
is unknown, select the highest range (3000 AAC / 5 AAC) on the switch probe inside
the handle. Clamp the probe around the conductor with the arrow pointed toward the
load. Select the lower range until you obtain the best resolution. Read the value display
on the DMM and multiply it by the range selected. If the reading equals 2.59 A on the
1000/5 range, the current owing through the probe is 518 AAC (2.59 A x 200).
■For the best accuracy, carefully center the conductor inside the probe jaw, avoid if
possible, the proximity of other conductors which may create noise.
