ATU-100 reads power output high


 

Recently acquired new ATU-100 (AliExpress). ?All functions seem to work appropriately with the exception of the power output reading. ? Knowing the input watts is 50, the ATU will reads 60-70 watts o/p. ?With input of 70-80 watts, the ATU will register 100+ watts o/p.
Question for the group: is this a firmware related issue. ?If so, what cells need to be altered to what value to bring this ATU into line?
I know how to connect the Picket 3 and assemble the programmer files. ?The mfg of this ATU has glued all the jumper cable connections, so it is not a trivial experience removing the glue and reconnecting the sockets. So, before I begin to ¡°excavate¡± the connections, I thought I would try to confirm this is a firmware issue.
Any help would be appreciated.
