[volt-nuts] 3458a RAM batteries - longer life if unit is continually powered?

[new]

The question is... if the 3458 RAMs store the calibration "magic" numbers.... if the ac (main) power is turned off, does it mean the RAM batteries are now under load to preserve the data?

If this is the case, would it be best to leave the unit on a UPS and keep it on 24/7/365? (But... will this kill the display?)

That way, it would never lose the cal magic, right?

If the cal constants are in the RAMs and the RAM batteries go dead, the 3458 needs to go back to Loveland, right?

Does any "RAM" error, HI, LO, etc. mean that it's time to go to Loveland?

Sorry for all the questions, I'm sure they were answered in the past - I'm new here!
