Iron Clamp Meter RMS
This function is intended for measurement of AC currents (leakage currents, loads currents,
noise currents) using iron current clamp.
Figure 11.88: Iron Clamp Meter RMS example
Flex Clamp Meter RMS
This function is intended for measurement of AC currents (leakage currents, loads currents,
inductive currents) using flex clamps. Wrap the measured object with the measuring clamp.
