Some time ago, we sent out one of the multimeter for calibration. It came back, the report said, it was outside of the specification (some 500%). So no adjustments were made, as if any adjustment was to be made, the DMM would be within it's acceptable range, right?
BTW I sent the report to Keysight, asking for a repair, as it was under warranty. They replaced it, no further question asked.
On the other hand, we do calibration of our own equipment. What we do, we set a variable, to have the measured quantity match the real world value.
On yet another occasion, there is a 3458A, it can do automatic calibration, where it sets the variables based on an internal reference, called "Auto cal"
So go figure, there is calibration, calibration and calibration, meaning completely different things.
