2.5 Two significant figures plus a third figure rounded to either 0 or 5.
3.0 Three significant figures.
3.5 Three significant figures plus a fourth figure rounded to either 0 or 5.
For example, the table shown next illustrates example values displayed using specific
significant figure options.

Reverse Mode
The Reverse Mode option (shown next) essentially enables you to set your gauge to control a
fan device in reverse of normal operations. For normal operations, leave the Reverse Mode option
set to No, meaning the feature is disabled. This is the default configuration for your gauge.
