Laval:
I couldn't fine a 1000 pf 0.1% cap for calibration of the Coulomb range so i got a variable cap (25 pf - 465 pf) that I will put in parallel with a 620 pf cap to trim to 1000 pf. Since my LCR is a 0.1% device, I should be abl;e to get to 1000 pf at 0.1% precision (should I need to calibrate the unit). The only thing I can't get atm is the 100 G resistor.

I should receive my cable and connector tomorrow, I'm not too optimistic about it since it is ridiculously cheap.
