1. Determine the current range to be measured
2. Will the signal(s) measured be AC, DC, or both? For an AC signal(s):
2.a. determine the frequency of signal(s) to be measured
2.b. determine the bandwidth required for measurments
3. Know the diameter of the conductor
Current probes allow you to measure DC or AC current. Yokogawa's selection of current probes allow measurements ranges up to 500 ARMS and bandwidths up to 100MHz.
