4-20mA SETPOINT
Default mA output is defined by the mA configuration in the standard
setup.
(page 16)
Choosing 4-20mA SETPOINT fixes the 4mA to the
programmed 4mA setpoint. The span of mA range is set with the 20mA
point. The mA current increases as the actual mV/pH moves away from
the setpoint. In UP mode the signal current increases as the mV falls below
the setpoint. In DOWN mode the signal current increases as the mV rises
above the setpoint.
Linear and 5 non-linear settings help to further fine tune a dosing setup.
The effects of the non-linear functions are shown in Fig. 19

The DPH-64 automatically returns to the main window after 2 minutes if
left anywhere in the configuration or calibration menu.
