[volt-nuts] Prema 6048 zero offset problems

Starting with a warmed up Prema 6048, if I power it off and then on, select 20V DC range, 4 second integration and connect to the 10V output of a Fluke 732A, I get a reading of: +10.47 If I reverse the polarity of the cables and allow the reading to settle down for a minute, I get a reading
