。In the verticality calibration of the present invention, it is preferable that the displacement from the vertical state of the object to be measured is, for example, within about 1 degree in a portion corresponding to the length between the distance detectors 2 and 28. can be efficiently applied to the calibration of objects within several hundred μm. For example, if the ADJ lighting of the verticality indicator lamp 5 has been calibrated by the verticality calibrator 11 at another position as described above, the device 1 can be calibrated vertically. The electrode or tool to be calibrated is installed on a processing stand or processing table that serves as a horizontal reference for electrical processing or machine tool equipment that is temporarily attached to a spindle, ram, or processing head, etc., and the electrode, etc. The spindle, etc. is lowered to almost directly above the processing table, etc., and the processing table, etc. is moved by operating the cross table, so that the distance detector 2.2S of the tilting plate 1b of the apparatus 1 and the electrode, etc. are brought into contact with each other. Side plate 1b where the vertical accuracy of the electrodes etc.
By lightly pressing the electrodes parallel to the surface of the electrodes and re-tightening them, the perpendicularity of the contact direction of the electrodes will be within the several hundred micrometers.

するものである。Next, from this contact state, the processing table, etc. is moved manually, electrically, or by NC operation, etc. to separate the device 1 from the electrode, etc., and the rightmost light emitting diode of the device setting position indicator light 3 lights up, and the knob 411 is set to CAL. light emitting diode lighting,
Then, by moving the device 1 again, the distance between the distance detector 2S on the SET light-emitting diode lamp lighting side and the corresponding position of the electrode facing it is adjusted so that the output of the detector 2S is at point S. This time, the verticality of the electrodes etc. is controlled so that the ADJ light emitting diode of the verticality indicator light 5 lights up.

ある。In this case, there are 7 on each side of the ADJ of the verticality indicator 5.
Since an appropriate number of light emitting diodes such as ~10 are provided, if the verticality to be calibrated of the electrodes, etc. is within several tens of μm, the verticality indicator lamp 5 can be adjusted according to the direction of its inclination.
Since either the left or right light emitting diode is lit, visually check the direction and amount of verticality to be calibrated using the indicator light 5, calibrate the verticality of the electrode, etc., and turn on the ADJ light emitting diode. This is to fully tighten and fix the bolt.
