How to scale for AI830 RTD
Hi, i would like to ask how do i do scale change for AI830 RTD in freelance?
I understand for AI810 is 0 to 28480 for 4 to 20mA.
But i'm sure RTD is totally different? My range for the PT100 is 0 to 100 dec C. So how should i key in my scaling? Is it the same as AI810?
Your scale should be 0 to 32000.
For all analog process values (like temperature) measured by S800 modules You get a -100% ... +100% signal coded into -32000 ... +32000 int value. So as 100 dec C is your 100%, You simply set scaling from 0 to 32000.
Hope this helps,
