Dear All,

 

I don't understand how I can convert the hexadecimal value that I found in AIRMS, AVRMS, AWATT to the true value. for example :

I used 230V as voltage source. and CT with this caracteristics 5A-333mV.

my load is 1,74 A that gave me 163mV . I found those values :

 AIRMS = 153A1D  === ??? A

AVRMS = 294354  === ??? V

AWATT = 6C84C === ??? watt 

 

Could you help me to get true values from this register value ?!

 

 

Regards,

Nouredinne
