Conversion/Calibration of Galvanometer into Voltmeter/Ammeter Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12123
Indian Lab Suppliers supplies the Conversion/Calibration of Galvanometer into Voltmeter/Ammeter (Product ID: 12123) as part of its electronics engineering lab equipment range. It is a self-contained board for converting a galvanometer into an ammeter and a voltmeter of chosen ranges and calibrating each against standard meters.
Quick Answer
To make an ammeter, a low-value shunt is connected in parallel with the galvanometer so that full-scale deflection corresponds to the chosen current; to make a voltmeter, a high resistance is connected in series so that full scale matches the chosen voltage. The board has a 65 mm centre-zero galvanometer (±30 divisions), a 0–5 V DC, 200 mA continuously variable regulated supply, and 65 mm reference meters (0–5 V DC voltmeter and 0–200 mA DC ammeter) against which the converted meters are calibrated. It runs on 230 V ±10%, 50 Hz and comes with seven 4 mm stackable patch cords.
