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 SR759
•
Connect the black and red terminals to the 2V
AC
range of your DMM or voltage measuring instrument.
Select the appropriate current range (1000/1V). Clamp the 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
selected. (e.g. If reading = 185mV, the current flowing through the probe is 185 x 1000 = 185,000mA =
185A when 1mV/A range is selected.)
•
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.
MAINTENANCE
Warning:
•
For maintenance use only original 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 instrument, do not get water or other foreign agents
into the probe.
Cleaning:
To ensure optimum performance, it is important to keep the probe jaw mating surfaces 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.
REPAIR AND CALIBRATION
You must contact our Service Center for a Customer Service Authorization number (CSA#). This will ensure
that when your instrument arrives, it will be tracked and processed promptly. Please write the CSA# on the
outside of the shipping container.
