Current probes
Several Dranetz-BMI current probes can be used with the PowerVisa. Typical current
probes are illustrated on page 2-10. Refer to Appendix A for descriptions and part
numbers of probes and adapter cables. Refer to Appendix B for specifications of
current probe models TR2500 and TR2510.
NOTE: The TR2500 can perform all current measurements except high frequency
transient detection.
Probe positioning: An arrow marking on the handle is a guide to ensure that you
position the probe with the arrow pointing towards the load when monitoring the line
conductor. Correct position of the probe is necessary for correct power measurements,
where in-phase voltage and current measurements are necessary. A positive watts
reading indicates that the probe is pointed towards the load. A negative reading
indicates that the probe is pointed towards the source.
