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 SR701/SR704
Connect the black lead of the curr ent 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 (2A AC range).
Clamp the probe around the conductor to be tested with the arrow pointed toward the load. If the reading
is less than 200mA, select the lo wer range until y ou obtain the best re solution. Read the v alue display
on the DMM and multiply it by the probe ratio (1000/ 1). (If reading = 0.659A, the current flowing through
the probe is 0.659A x 1000 = 659A AC).
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 w ith a meter, it is important to select the r ange that prov ides the best
resolution. Failure to do this may result in measurement errors.
Make sure that probe jaw mating surfaces are fr ee of dust and contamination. Contaminants cause air
gaps between the jaw s, increasing the phase shift betw een primary and sec ondary. It is v ery 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 in strument, do not get w ater or other foreign agents
into the probe.
Cleaning:
To ensure optimum performanc e, it is important to keep the probe jaw mating surf aces 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, then gently clean with a soft oiled cloth.
