I'm using the ZSC31050 paired with a pressure sensor. My boards are back and working. I have followed the evaluation board app note to calibrate the pressure sensor across the desired range. The polling of the read out data with averaging yields a really good result across the full range. Very linear. Very nice.
The 0-10V output changes, but the range is off. I'm trying to figure out how to calibrate it. I read the 0-10V app note, but that doesn't seem to be enough. I have monkeyed with the "Tools -> Output Voltage Adjust" but I haven't been able to understand it well enough to get results.
Is there a step-by-step guide for calibrating the output voltage?
Thanks.
Brian,
Can you attached screen shots of the calibration window with settings that you have tried. Also, I will check around to see if we have something more on this operation.
Thanks. I thought I posted, but apparently not. But now my account may be locked so I may not be able to post at all.I can't find any instructions for how to use the output calibration window. I tried figuring out how to get it to adjust the gain and offset, but was not able to figure it out. I was hoping to see some instructions similar to those that explain how to calibrate the range and resolution of the sensor itself.
There is not a lot of information about this, and I couldn’t find any document that specifically addresses it besides the Functional Description. There is a description of the register settings in Table 5.8, which fine adjusts the regulator voltage from -1% to 0.75%VDDA in 7 steps:
Then there is a brief description of the voltage regulator with some FET recommendations. But that’s about it.
