Hello Everyone,
I recently bought a eval-AD5933 board to do some cure monitoring of a resin system. For this, i want to calibrate my system with a 1MΩ resistor. However, i keep running into issues.
When i connect a 1MΩ resistor to both the Rfb and Z pins on the board and calculate the gain factor, it gives a value of 1,01191066098752E-10. When i then start a frequency sweep, the resulting impedance is very low, around 0,0001 Ω. I have tried many combinations of connecting other resistors, leaving out the Rfb resistor, leaving out the Z resistor, connecting to the T2&T3 pins but nothing seems to be working. Has anyone else had this problem or does someone have a solution?
Thanks in advance,
Roy
