Figure 9-8. Example of User Calibration When Output Range is 0~5 [V]
Low and High Values for each output range are listed in the Table 9-3 .
Output Range Low Value High Value
0~5 [V] -1,250~1,250 23,750~26,250
1~5 [V] -1,250~1,250 23,750~26,250
0~10 [V] -1,250~1,250 23,750~26,250
-10~10 [V] -26,250~-23,750 23,750~26,250
0~20 [mA] 0~1,250 23,750~26,250
4~20 [mA] -1,250~1,250 23,750~26,250
Table 9-3. Low and High Values for Each Output Range
User Calibration Method 9.4.3
Perform the user calibration of output deviation according to the following procedure.
1. Set the Low Value and High Value to the default values.
-
Analogue Output Calibration Low Value (2302h): Sets Low Value to the default value
- Analogue Output Calibration High Value (2302h): Sets High Value to the default value
- Refer to the following table for the default values of Low Value and High Value for each Output
Range.
Output Range Default Low Value Default High Value
0~5 [V] 0 25,000
1~5 [V] 0 25,000
0~10 [V] 0 25,000
-10~10 [V] -25,000 25,000
0~20 [mA] 0 25,000
4~20 [mA] 0 25,000

2. Adjust the Write Analogue Output 16bit (6411h) value to output the Low End value. Record the digital
data when it reaches the Low End output.
