Hello John,


Could it be that the meter was calibrated to compensate for the fact
that when it's hooked to a battery, it only supplies current when the
charger exceeds the battery's voltage, while on a lamp it would draw
current from zero on up?

No.


Then maybe the meter was calibrated so it would adjust the indicated
current according to the consumer price index. Now wait, with a build
date of 1965 that doesn't computer either...
