Sample Program for Non-Contacting Electrode Method
Example 13-3 shows a sample program to measure dielectric materials (non-contacting
electrode method) (for HP Instrument BASIC). You can find the source file of this
program, named permi_nc.bas, on the sample program disk. This programs is very similar
to Example 13-2, and therefore only its listing is given here.
