Abstract: | A microprocessor-based, switched-battery capacitance meter has been developed. It consists of an analog part, based on a previously designed capacitance meter, and a digital part in which a microprocessor and a timer perform the main functions. The capacitance is measured indirectly by means of a time constant measurement. Two phases of the measurement process are involved in measuring the capacitance. The first phase, when a capacitor is charged, is based on the software counter-timer measurements. The second phase, when the capacitor is discharged, requires a hardware timer controlled by the microprocessor. The digital hardware reflects a different approach than used for the previous construction |
