Calculation error of a single-phase electric power meters

The application is designed primarily for power supply companies, asset management companies, etc., are engaged in a test of electric power meters. The application calculates the error of metering device, as follows:

in the U, in the drift value of the voltage measured by the voltmeter; in the I, and the input current is measured by an ammeter or clamp meter. After clicking on the green button "Calculate Pseti" comes the calculation of the value network capacity. Next is the payment capacity of DMCs, which takes into account el.schetchik. In the A, on (imp) kWh choose the gear ratio metering device. Click on "Start" button and hold, it occurs the pulse time, the number of which is stored in the n field of the (imp). Pressing the green button "Calculate Psch" calculated power DMCs. Pressing the green button "calculation error" is calculated taking into account the error of the instrument. Checking the counter mechanism is tested in another window (check counter mechanism). Pressing the green button "DMCs W" in the value of the power window will appear, which was calculated in the previous screen (calculation error in the metering device 1F. El.seti). Pressing the green button "Estimate" calculation appears. The screenshot shows an example, which means that for 3 min. metering "wound" 100 Wh, at 2000 W load.
