UM344-2ON-LINE AND OFF-LINE OPERATION

5.1.3.1 Display Functions

The numerals displayed on the Digital Meter represent the value

 

of the PROCESS VARIABLE (PV) when the “PV”

 

annunciator is lit; see Figure 5-1. The units associated with PV

 

are chosen during transmitter configuration of the OPERATOR

 

DISPLAY BLOCK. Refer to section 5.1.1.2. There are three

 

OUTPUT DISPLAY CODE choices listed in Table 5.1 that

 

describe what information is displayed and how it will be

 

annunciated.

 

The VALVE (V) is always displayed as a percentage of

 

controller output and the “V” and “%” annunciators will be lit.

 

The SETPOINT (SP) is displayed in the same units as the

 

PROCESS VARIABLE (PV). When the controller is ON

 

depressing the FULL SCALE pushbutton will toggle the display

 

between “PV” and “V”. The ZERO pushbutton will toggle the

 

display between “PV” and “SP”.
