No, most calipers can only do relative measurements. It’s constantly counting how many 0.01mm the head has moved so it doesn’t lose track of where 0mm is located. Turning on the LCD when the volatile counter changes value is a free feature since the mcu is always on.

Of course better calipers do absolute measurements, but they’re too expensive to scribe lines with and therefore useless for hobbyists.

It is not just hobby people scribing lines. Just saying.
