Auto-Ranging
When manual range selection is enabled, pressing this enables auto-ranging.
The most suitable measurement range is then selected automatically.
The auto-range setting (on/off) for the ΩV function applies to both resistance and
voltage measurement.

range selection
Press the AUTO key again. The range can now be changed manually.
• Depending on the state of the test object, auto-ranging may be unstable. In
this case, select the range manually, or increase the Delay time.
• Auto-ranging is not available when Comparator or Memory functions are
enabled (ON).
• Refer to "Specifications" (⇒ p.171) for details about accuracy.
