2.5.1 Display Overview
The Liquid Crystal Display (LCD) of
Į
lpha CON 560 conductivity controller
has two alpha-numerical displays (Upper and a Lower).
x
Upper display:
Measured conductivity value is displayed when the
controller is in normal operation (measurement) mode.
x
Lower display:
Measured temperature value is displayed when the
controller is in normal operation (measurement) mode. In conductivity
calibration mode, measured conductivity values are displayed here.
The two displays indicate function names, options & settings in Setup mode.
Refer ‘Appendix 4 - Abbreviations Used in LCD’ for more details.
The LCD also consists of various mode indicators, status annunciators and
unit of measurement indicators.
