Pulsed converter of capacitance of a sensing electrometer to voltage or current

1. A converter of the proposed type has a high sensitivity, as a consequence of which its output current can be measured directly by an indicating instrument without any amplification; it is simple and reliable. 2. The sensitivity of the converter increases considerably with a decrease of the maximum angle of deflection α0, and in the region encompassing the origin of the coordinates the output current of the converter varies within wide limits but the characteristics iav.l=F(α) can be considered linear. 3. To measure the output current of the converter it is best to use instruments with small internal resistance, since the sensitivity of the converter will be higher; in a certain region of values of R l the sensitivity of the converter does not depend on the load resistance and decreases with its further increase. 4. The sensitivity of the converter increases with the frequency of the supply voltage, and it is desirable to select frequencies lying in the linear part of the converter's frequency characteristic.
