Description

Determines whether to use the fixed point display when displaying both the primary and
secondary parameters. In the following cases, the fixed point display is always used
regardless of this setting (the value of the highest digit is also fixed).

•

When displaying deviation as a percentage in the deviation measurement mode.

•

When displaying the results of D and Q of the secondary parameter.
