Page 7: Measuring Load Current
• Depending on the magnitude of the input current, the jaws may generate a sound due to resonance; however, this does not affect any measurement. • When you cannot find the magnitude of an input current, disable the filter function and start measurement using the auto range or 600.0 A range.
