| Q. I have one of your thermocouple units and the values that I
am getting is twice the value that I should be getting. Why is this happening and how can
I fix it? A. All the final values of the thermocouple go to the %AI. Before these values are correct, they must be divided by 2 or 10. This number is dependent on the resolution of the system. A system with a resolution of .5° C will be divided by two, but a system with a .1° C will be divided by 2. This is division is done through a simple ladder logic program.
Q. What should I do if my readings are slightly off on my Strain Gage, Thermocouple unit, or RTD module? A. Changing the digital filtering, which is typically byte 2, could reduce this problem. This number determines how many samples of a particular signal are taken in a given time. A high digital filtering number such as 110 would give you considerable amount of samples compared to a digital filtering number of 10. The trade off is time. As the number increase, the response time also increases. In an environment where noise is a factor. A high filter number should be used to insure an accurate reading from the modules. |
