Smart meter program?
Thread Content
Does anyone have a program for smart digital displays? Processing scale numbers: Pt100, Pt10, Cu50.N, K, E, T, J. Full signal processing for 0-20Am and 5-36VDC. I’d like to know more about this. Thank you, experts! This post was last edited by Chifeng on 2009-2-22 at 08:56
You have already seen the scale marks above; the range is the range indicated by those scale marks； As for 0-20Am 5-36VDC, it depends on the accuracy shown by the display; if it’s 4 digits, but the value exceeds that range, then a notation indicating how many tens more are needed can be added next to the display.
I don’t understand what a “program” is. As for the functions of an intelligent digital display, they mainly include universal signal input and the ability to change the measurement range; all the scale markings mentioned by the original poster can be used
Thank you, friend. Before, we did everything by ourselves, assembling things according to the original circuit diagrams; the displays were used back then. Now everything is part of intelligent systems, and production has become very simple. It’s just that I’m not very familiar with microcontrollers, so I don’t quite understand the programming aspect related to intelligent chips, haha
Thank you for your concern. The scale number can be entered; as for 4-20mA and 5-36VDC, they are standard signal parameters
The functions of intelligent digital displays mainly include multi-functional signal input and the ability to set any range; all the division values mentioned by the poster can be used.
