The user can use y = (a) x (read address value) +
(b) this equation to determine the display
numeric value (y). For example, if Gain value (a)
is 2 and Offset value (b) is 3, when the read
address value is 3, then the display numeric
value will be equal to (2) x 3 + (3) = 9.
If Gain and Offset value is a decimal, please set
the data format as “Floating”.
If Round off option is selected, after the
operation of the equation above, all numeric
values can be rounded off and display on the
