Meters provide a graphical and a numeric representation of instrument readings. The graphical representation allows you to visually compare the PV with reference values such as alarm limits and/or user-configured reference values (e.g., the "tracker" or optimal range).
Many of the meters have variations that allow them to also be used to represent a controller. These variations include additional elements such as output (OP) and feedback indicator (FB).
You can insert multiple instances of a meter in duplicate or triplicate by using the Multiple Meter.
Meters are associated with equipment, and require the following items to be defined:
