Check the operating rpms the rpms determine the voltage and frequency and can be adjusted at the governor spring setting adjust it until the voltmeter reads the required voltage set slightly above to allow for rpms drop under load for example if 240 volts set around 250 volts and that will drop back to 240 volts under load if 110 set around 115 and that will drop back under full load both frequency and volts are dependant on rpms

Check the operating rpms

set slightly above to allow for rpms drop under load
for example if 240 volts set around 250 volts and that will drop back to 240 volts under load
if 110 set around 115 and that will drop back under full load
both frequency and volts are dependant on rpms
