The resolution is the measuring range shown in
the following table, divided by 4000. The resolution
will not be improved by using limits other than
those in the table. Even though the stated
resolution is fractional, the digital display only
shows degrees in whole numbers.

Examples:
A Type R Thermocouple sensor with a DPRIOO Temperature Input
Module has a sensing range of 0 to 1500X. The measuring range
is 0 to 5OO'X, set with FCODE 24 thru 26. The controller sees only
that portion of the sensor signal lying within the defined measuring
range. The digital display now shows temperature between 0 and
5oooc.
The displays can now be further limited by using the setpoint limiting
function to limit the maximum setpoint range (FCODE 106, 9, IO) to
0-300°C. If setpoint limits of O°C and 300°C are entered, the digital
70
display indicates exact temperatures between 0 and 500°C, butthe
60
50
bargraph indicates O°C at 0% abd 300°C at 100%. At 70% on the
40
bargraph, the temperature is 210°C.
