This is a tool used to calculate accuracy of energy meters. Energy meters are devices that are used to measure the electricity consumption in terms of KWH (Kilo Watt Hour), where 1 KWH is the amount of energy consumed by 1KW load in 1 hour. To calculate the accuracy of energy meter, connect supply and load with energy meter with proper connections. You can use either AVO Meter (Ampere, volt, ohm) or Power Meter (Watt Meter) for measuring the load applied to meter.
*************************** AVO Meter **********************************
Use voltage terminal of meter to measure the voltage of supply applied to meter and use current terminal of meter to measure the amount of amperes flowing through meters with connected Load, note down both these values in app.
