Determine the offset data.
Determine the analog output value for the digital output value of 0.
Set the analog output value in mV for the voltage output mode, and the analog output value in μA
for the current output mode.
Example: To set the offset value of 1 V, set 1000 mV.
5
Determine the gain data.
Determine the analog output value for the digital output value of 16000.
Set the analog output value in mV for the voltage output mode, and the analog output value in μA
for the current output mode.
Example: To set the gain value of 3 V, set 3000 mV.
(5-1)÷2+1 = 3 V (3000 mV)
