In order to conduct a reliable and accurate probe calibration, the calibration zero
point which is later required must firstly be positioned via the probe's raw value to the
electrical zero point (see section 2.7, page 15). This is because the inductive probe
measures at the electrical zero point most accurately. The calibration of the probe in
our example is as follows: for the MAX value, a 2.000 mm gage block is used, the MIN
value is obtained on a measuring plate; however, a 1.000 mm gage block would be the
ideal electrical zero.
