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 · Connect the black and red leads to the Ampere AC range of your DMM or current measuring
instrument. Select the appropriate current range (10A AC). Clamp the probe around the conductor to be tested. If the reading is less than 500mA, select the lower range until you obtain the best resolution. Read the value display on the DMM and multiply it by the probe ratio (1000/5). (If reading = 1.59A AC, the current flowing through the probe is 1.59A x 200 = 318A AC) · For best accuracy: carefully center the conductor inside the probe jaw, 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.
Maintenance 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. The following is the recommended procedure for cleaning the probe jaws: Use a very fine sand paper (fine 600) to avoid scratching the jaw, then gently clean with a soft, oil 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. If the instrument is returned for calibration, we need to know if you want a standard calibration, or a calibration traceable to N.I.S.T. (includes calibration certificate plus recorded calibration data).
