Note!
• Note that this setting only affects the reading as it appears on the display, it has no
influence on the accuracy of the system's calculations.
• The places after the decimal point as computed by the measuring device cannot always
be displayed, depending on this setting and the engineering unit. In such instances an
arrow appears on the display between the measuring value and the engineering unit
(e.g. 1.2 → l/h), indicating that the measuring system is computing with more decimal
places than can be shown on the display.
