4.2 Function Description
This section describes the panel keys and parameter setting keys in alphabetical order.
4.2.1 AUTO Key (Measurement Range)
Switches between measurement auto range and fixed range.
Auto range: Measures with the optimum range between the limiter range and the minimum
range. AUTO indicator turns on.
Fixed range: Measurement range does not vary. AUTO indicator turns off.
If the measurement function and the source function are different, the range is fixed
at the limiter range.
If the measurement function and the source function are the same, the range is fixed
at the source range.
For more information on the measurement auto range, refer to Section 5.2.5.2, “Measurement Ranging.”
4.2.2 DOWN Key (Source Range)
Decreases the source range by one step.
However, it is impossible to decrease a range that cannot output the currently set source value. In this case,
the source range setting mode is set to LOCK.
4.2.3 FIT Key (Source Range)
Switches between the source range set modes, FIT and LOCK, to decide the source range.
The source range set mode is retained at each source function.
FIT status: Sets the optimal range for the input source value.
FIT indicator turns on.
LOCK status: Fixes the present source range.
FIT indicator turns off.
NOTE: Switching FIT/LOCK does not change the source range.
