5.5 Configuration Settings
Configuration settings let you configure the pH Monitor to different measurement &
operation modes & reset the pH Monitor to factory defaults.
Asymmetrical Operation Mode (ASY):
This is the default mode of operation of the pH Monitor, which is suitable for most
applications where sample (or process) liquid is not interfered by adjacent electrical
noise.
Symmetrical Operation Mode (SY):
This is mode of operation is recommended for applications where sample (or
process) liquid is subjected to high electrical interference and therefore the pH
reading becomes unstable. When the pH Monitor is set to symmetrical mode, you
should immerse the potential matching pin in the sample (or process) liquid or use a
pH electrode with built-in potential matching pin. The ‘MEAS’ indicator blinks when
the pH Monitor is set to Symmetric mode.
