Measurement Ranges (1)
A measurement range determines the highest value the Meter can measure. Most Meter functions have more than one range.
See “Accuracy Specifications.”
A. Selecting a Measurement Range
Being in the right measurement range is important:
••
If the range is too low for the input, the Meter displays to indicate an overload.
••
If the range is too high, the Meter will not display the most accurate measurement.
B. Manual Ranging and Autoranging
The Meter has both manual range and autorange options:
