10-14-4. Output related scale correction
Detailed procedure of output related (Current output/voltage output, transmission signal output) scale
correction is as follows.
1. Preparation of measurement devices
Input to be corrected Required measurement devices and tools
Current
output/voltage output ① Digital multi-meter
･ Accuracy: Less than ±0.05%.
Transmission signal
output
①
Digital multi-meter
･
Accuracy: Less than ±0.05%.
2. Wiring
[Current output/voltage output]
[ Transmission signal output ]
3. Scale correction
① Preparation and conduction
･ By making operation environment of the controller as 'standard operation condition' the controller is
stabilized.
･
After confirming the wiring, it is stabilized by making relation of the controller and the measurement device
stable.
②
Indicator check before scale correction
･
Refer to the following and perform the output check (3 places) before correction.
Minimum value :
□□
mA
(Input value : 0%)
Medium value:
□□
mA
(Output value: 50%)
Maximum value:
□□
mA
(Output value: 100%)
Indicator check before
correction
Indicator check after
correction
③
Setting zero correction value
･
Output, output value 0%.
･
If minimum value is positive as compared to ideal value, set negative value for zero correction and if
maximum value is negative as compared to ideal value, set positive value for zero correction.
･
By referring to the digital multi-meter, set the zero correction value such that it matches the ideal value.
