Application menu

The choice of a design method is required to calculate one of the analog front end

components, either Ks or R1 according to the chosen method. A target value is suggested

for this component, and its real value should be chosen as close as possible to it.

Once all these data are input, the “Output” section gives some information about the meter

ratings, like output frequencies, voltage and current maximum ratings and target values of

RMS registers at specified load.

Use the “OK” button to save and close form, “Apply” to save only and “Cancel” to exit

without applying changes.

The “Go To Calibration” button opens the calibration wizard form, if a hardware interface is

selected.

Calibration wizard

To open the calibration wizard, the board has to be connected (through “Option”-”Interface”

menu) and powered on.

The calibration wizard consists of four steps. In the first one, shown in Figure 7, the user has

to insert the board parameters and the working point for calibration, and the number of

current channels used.

In the second step (Figure 8), the user has to select a design method, choose mutually

compatible sensor sensitivities for voltage and current so to achieve the calibration.
