| Calibration with external calibration reference sensors offers advantages especially for short probes, since both sensors are introduced at the same depth in the bore. The temperature of the external calibration reference sensor, of the test piece and the difference between the two appear on the display. Thus this calibration can also be performed simply. The control functions are transfered on a external calibration reference sensor. The measuring instrument is available in two versions: • Retrofittable without difficulty in the TP 38 000 E • Available as desktop model TT Scan |
