Emerson MMI-20019043 User Manual

Setting Display Precision determines the precision (number of decimal places) shown on the
display. You can set Display Precision independently for each variable.
Setting Display Precision does not affect the actual value of the process variable.

1.

Select a process variable.

2.

Set Display Precision to the number of decimal places you want shown when the
process variable appears on the display.

For temperature and density process variables, the default value is 2 decimal places.
For all other process variables, the default value is 4 decimal places. The range is
0 to 5.

The lower the selected precision, the greater the process change must be for it to be reflected
on the display. Do not set Display Precision value too low or too high to be useful.
