The following introduces the five-point calibration tutorial of the fourth-generation coating thickness gauge of Guoou
Calibration can use the calibration block that comes with our instrument, but we recommend industrial users to calibrate on uncoated workpieces, so that the measured values are the most accurate.
Because the calibration block that comes with the coating thickness gauge may not be 100% consistent with the material of your workpiece.
Let’s start the tutorial: When the instrument is turned on, press the “left key” to enter the menu, press the “down key” to find the calibration, press the “left key” to enter, press the down key to find “five-point calibration”, and then press the “left key” "Start the five-point calibration.
The coating thickness gauge prompts us to measure the uncoated substrate. After pressing the instrument vertically on the substrate for 2 seconds, lift the probe up .
It will prompt us to measure the first diaphragm. We find the diaphragm with a value of about 50 microns and measure it. If the value is the same, no adjustment is required. Its adjustment is consistent with the diaphragm value,
Then we measure the second diaphragm, find a diaphragm of about 100 microns, and adjust the measurement,
Then measure the third diaphragm, find about 250 microns to measure and adjust,
After the fourth measurement, find a diaphragm of about 500 microns to measure and adjust,
Finally, the fifth diaphragm is two diaphragms of about 500 microns for superimposed measurement, and the measured values are adjusted to be consistent, and the five-point calibration can be completed.
