New electronic measurement, control devices
Abstract
The electronic control device serves to measure the capacitance of the loss factor tg delta and the leakage current of tantalum and electrolytic capacitors. During the measurement of the leakage current, the capacitor can be polarized from an internal source with constant voltage regulated continuously from 0 to 100 V, or with a voltage of up to 500 V from an external source. The instrument has a system signalizing the loading state of the capacitor and a system for unloading it. The meter has two readout fields with LED display indicators: 3 and 5-digit for measuring the capacitance and the leakage current; 3-digit for measurement of tg delta and polarization intensity. The choice of the range for capacitance measurement can be done manually or from outside. The capacitance measurement is performed by the four-point technique in a serial replacement system. The meter with the corresponding interface block can operate in measurement systems according to IEC/ISP II standard.
