1 This key is used to select the pH measuring
channel control mode (proportional or hys‐
teresis mode).
This key (1) is used to select the pH measuring channel control mode (proportional or hysteresis
mode):
Proportional mode is a linear calculation, with the drive control based on a single component,
n
the proportional mode.
Hysteresis mode is a two-point control, with the hysteresis value being the gap between the
n
setpoint and the measured value.
If the measured value is above the highest point, then the control activates the falling actuator.
If the measured value is below the highest point, then the control activates the rising actuator.
The previous actuator remains active between the setpoint and the lowest or highest point.
