                    How does the count of the square switched-current sum works?
- 
                    If the power transformer is in No-load condition, does the AVR indicate the secondary winding voltage, or does it show a message?
- 
                    Can the AVR be used to regulate a transformer with two secondary windings?
- 
                    If the AVR does not have the optional 3 (Position measurement), will it switch the tap automatically according to the load voltage level?
