Why does my display show [HH] instead of the Process Value?

This error message indicates that the Process Variable is above the upper limit of the range. For example, if the temperature is 305C when the range is set for 0 to 300C. The 3 digit display as used on the model 6500 will show [H].

This message can also be generated if the input is incorrectly wired, or the input code and/or jumper are not correctly set for the type of signal applied.

Check the following sections in your product manual to correct these conditions:

Connections and Wiring
Internal Links and Switches
Configuration Mode - Input Code
