Mode 2 for CR#1:
GAIN = 20mA(1,000LSB), OFFSET=4mA (200LSB).
Mode 3 for CR#1:
GAIN = 20mA(1,000LSB), OFFSET=0mA (0LSB).
GAIN:
Current input value when digital output is +1,000. Setting range
is -16 mA ~+52 mA (-800LSB ~ +2,600LSB)
OFFSET:
Current input value when digital output value is 0. Setting range
is -20 mA~+20 mA (-1,000LSB ~ +1,000LSB )

OFFSET:
Setting range is +4mA ~ +32mA (200LSB~ +1,600LSB)
The chart above is to adjust A/D conversion characteristic curve for voltage input mode and
current input mode. The conversion characteristic curve can be modified by changing the
OFFSET values (CR#18~CR#21) and GAIN values (CR#24~CR#27) depending on the
application.
Voltage input: 1LSB=10V/2,000=5mV. Current input 1LSB=20mA/1,000= 20
