It indicates digital output value separately with analog input signal to each channels so that you can see precise value without additional data processing. You can check Precise value for each analog input range.
Analog input | Precise value |
4 ~ 20 mA | 4,000 ~ 20,000 |
0 ~ 20 mA | 0 ~ 20,000 |
1 ~ 5 V | 1,000 ~ 5,000 |
0 ~ 5 V | 0 ~ 5,000 |
-10 ~ 10 V | -10,000 ~ 10,000 |
0 ~ 10 V | 0 ~ 10,000 |
