Good day All,
This is a Project to Adjust Specs & Build Lab / HMI 0-10V panel and is now published as below:
Small Lab / Bench General Purpose 0-10V Generator with better than 0.5% accuracy
Meant to suit for Preliminary project R&D or for small Labs equiment as a 0-10V Dual Outputs generator.
The project is in its following phase: Definition and Specification
Main description
- 2 channels 0-10V interface
- 5 mm Jack Input
- 4mm banana jack outputs
- Two outputs channels 0-10V
- Incremental Encoders
- 12V Power inlet
- 120 x 80 mm front plate
- LCD Screen
- 6 Push-buttons
Specifications
- Output channels

Hi Ruth,
I don't know how you guessed it but that's going to be the case, the device will be Uart controlled and thus computer interface through UI we designed.
At lease the idea to differentiate the generator is add a couple feature such as RLC meter (at least Precison R and C meters). That requires the device to have precise current control, once that's done, by customizing the embedded code, we can trick this device to act as a meter and calculate parts characteristics.
Even though it'd be interesting to implement a C = f(V) characteristics, I eared capacitance specially ceramics lowers with reduced Voltage, so can measure that.
Regards
Jean-François
