6. Check the standards at different frequencies. Use the series equivalent for the
two smaller resistors and the parallel equivalent for the two larger ones. R should
remain relatively constant and Q should scale with frequency (i.e. Q at 10kHz is
10 Q at 1 kHz). If any of the values are too far from the nominal values, recali-
brate that range.
7. Before making measurements, run open and short circuit calibration with the fix-
ture configuration to be used.
