Chapter 5 Display and Setting of Various Functions
This function controls the offset temperature to the circulating fluid
discharge temperature
Control range of the circulating fluid temperature is 15.0
When the circulating fluid temperature is set to 15.0
temperature to -20.0
adjusted to 0.0

Electric conductivity control method
When option DM is selected, circulating fluid flows to the DI filter via a
solenoid valve to control electric conductivity.
This solenoid valve can be set to always OPEN,or always CLOSED.
The factory setting is "CTRL: Electric conductivity control".
By pressing the [▲], [▼] key, always OPEN, or always CLOSED
can be set.
