Capacitance Meter

rE,:ay19.7 CAPACITANCE METER by J Peltz A smartly designed, inexpensive, yet accurate, analogue capacitance meter. The capacitance meter de- scribed here is intended to meet the need for an accurate, battery-operated, and low-cost instrument, which has no more features than strictly necessary for the testing and measuring of a wide range of capacitors. Considering that a capacitance meter is not the most frequently used of test instruments in the electronics workshop, a rela- tively simple design can have all the necessary features, and yet be accurate and reliable. The digital capacitance meter described in (I) is, of course, the ultimate as far as ease of readout and operation are con- cerned, but the cost of this in- strument may be considered rather high in relation to the number of occasions when the instrument is called for. • The present instrument can operate in conjunction with almost any multimeter that has a 1 mA DC current range with sufficient accuracy. However, it ...
