ADJUSTMENT
5-25. 10kHz MEASUREMENT ACCURACY ADJUSTMENT.
PURPOSE:
This adjustment eliminates measurement error due to stray capacitances on A12 and
A13 board assemblies and maximizes measurement accuracies at 10kHz measure-
ment.
Note
Each of the following adjustments are inter-
related. To achieve correct adjustments, do
not change adjustment procedure or sequence.

*After calibrating capacitances to within 0.1% and
resistances to within 0.02%, the dissipation factor
tolerance is £0.002 for each DUT.
Refer to ‘“‘Calibration of DUT’s” on page 4-2 for
the proper DUT calibration method.
