Main display
The Main display appears upon startup when one sensor is connected and the MONITOR

B, C: Measurement value: Second and tertiary values (small characters)
D: Unit for the primary value
E: Tag No. (user programmable)
F: Sensor No. *
G: Sensor wellness indicator (More ■ indicate the better condition.)
H: Hold/Wash indicators (appear only during the Hold/Wash operations)
J: Analog output display and parameter * (ex.: PH1…PH=Parameter, 1=sensor number)
K: Additional text (set in alphanumeric characters/user programmable)
L: Function buttons (Home, Zoom, Status, Execute & Setup)
M: Fault/Warning indicators (indicated in blinking only during Fault/Warning status)
* When the parameter of which measurement value is indicated is selected as a process
parameter, that is, mA output set on the Output setup (refer to the section 5.3, 8.2, 11.2, and
14.3), its Sensor No. is indicated as a white number in the black box, for example , and its
mA output is indicated as a bar at the bottom. At the bar, a parameter symbol is indicated.
NOTE
Measurement values on the display can be set independent of the process parameter.
