No AC probe prevents calibration. DC calibrated up to 500vdc. The cap and inductance not working right. Zeros but meter goes half way.  Here are the v2 v3 pins. It might be how the 6.3vac is hooked up to the probe. R9 does receive 6.3 vac. I will check on the 6.3 Vac path. Have not checked the total path.
