The device guarantees the highest accuracy after approx. 30 min operating
time. To conduct a reliable probe calibration, the calibration zero point that is
going to be used must first be positioned to the electrical zero point via the raw
value of the probe (see section 2.9, page 18). This is because the inductive
probe measures most accurately at the electrical zero point. A 1.000 mm gage
block would be the perfect electrical zero point for a probe calibration, like the
one in this example, where a 2.000 mm gage block is used for the MAX value,
the MIN value is obtained on a measuring plate.
