Mode 6 of CR#2~ CR#5
+4mA ~ +20mA, Gain = 12mA (19,200), Offset = 4mA
(6,400).
Gain (CR#34 ~ CR#37)
The current input value when the digital output value =
16,000.
Offset (CR#28 ~ CR#31)
The current input value when the digital output value =
0.

Adjusting D/A Conversion Curve of CH5 ~ CH6
You can adjust the conversion curves according to the application requirements by changing
the Offset value (CR#32 ~ CR#33) and Gain value (CR#38 ~ CR#39).
Gain: The voltage (current) output value corresponding to digital value 16,000.
Offset: The voltage (current) output value corresponding to digital value 0.
z
For voltage output Mode 0: 0.3125mV = 20V/64,000
