I asked: "Is the error a constant difference or is it a percentage of the result?"
Erik, the error is constant. Every time I do it, I get exactly 12.88 instead of 14.1V. I am using a variable power supply at this point, but it will never go over 15 volts. So I tried several voltages levels and I get misreads. I do not know if the percentage error is always the same in all That does not answer the question Let's try another way What does the thing read for 10V AND what does the thing read for 5V. Erik |
