  • Page 70 10. Characteristics of CLAMP ON PROBES (Reference Information) When a CLAMP ON PROBE is used to make measurements, the accuracy of both the CLAMP ON PROBE and the 8807-51/8808-51 will affect measurement accuracy. In measurements of the direction of a harmonic wave, current value, or other values, the phase characteristics of the CLAMP ON PROBE significantly affect the measured values.
