Scale page
Use the page key to call the scaling page. As our scale
range is the same as the input range, we can leave it
'Unscaled' and continue by operating the Page up key.
Scaling is used where an input signal (e.g. 4-20
mA) is used to represent another type of input (e.g.
0-500 gal/min), or where, a potentiometer wiper
voltage may be required to appear as, say, 0 to
100% instead of 0-1 Volts.
Value Format
This page allows us to set the position of the decimal
point for display.
Use the up arrow key to move the decimal point to our
required position (two decimal places).
