RESISTANCE, CAPACITOR METER CIRCUIT SCHEMATIC
The application circuit, called PICMETER, uses a PIC16C622 as a resistance and capacitance meter. The PICMETER uses a variation of the single-slope integrating converter. The linear slope and integrator of Figure 13 are replaced with the exponential charge waveform of an RC. The charge time of a known component is compared against the charge time of an unknown component to determine the value of the unknown component.
A schematic of the PICMETER is shown in Figure 16. All reference designators cited in this section refer to this schematic. Results are transmitted to a PC which displays the value measured.
