1. If set, you are prompted to open the circuit so that an offset capacitance measurement can be

2. If a cable compensation file is specified, the compensation information in that file for the selected

range and frequency will be loaded. If not, instrument default compensation is used.

3. A C-t sweep is performed.

DisplayCableCompCaps82 user module

This user module is used for Model 82 cable compensation. When this test is run, the nominal

capacitance source values saved by the SaveCableCompCaps82 user module are placed into a

spreadsheet for viewing.

status = DisplayCableCompCaps82(char *CabCompFile, double *Range, int RangeSize,

double *Values100 k, int Values100 kSize, double *Values1M, int Values1MSize);

Values100kSize

Values1MSize

Returned values are placed in the Analyze sheet; see Details
