Any thing you do other than record the current voltage reading will
introduce more uncertainty and increase drift unless you have a defect.
Replacing a defective part will start the aging process over again for that
part. Do not change anything if you can help it.
Agilent is a good cal lab to use as well. They will run it for a few days
and take readings a few different times and give you a report.
Most of the time the battery is not enough to keep the box hot until they
plug it in so they count on warming up a few days.
Hope that helps.
