Loading-Effects Reduction Using a Voltmeter in Series and an Ammeter in Parallel
نویسندگان
چکیده
This article proposes a method for reducing the loading effects when DC voltage or current is measured in linear circuit with digital multimeter (DMM). In proposed method, voltmeter placed series to estimate current, and ammeter parallel voltage, which opposite of conventional approach. Its application particularly interest equivalent resistance between nodes (current) under measurement high (low). comparison relative error up factor 104 lower if equals shunt (input) DMM (voltage) measured.
