Calibration of galvanising thickness gauges
If you find that the diaphragm measurement error is large or can not be measured when calibrated, please operate according to the following steps.
1, press and hold the on/off button until the display appears "CAL" (this process takes about 4 seconds), the display will show "F:H", then gently press the zero key to confirm (the probe must be suspended in the air).
2, press and hold the on/off button until the display appears "Ln" (this process takes about 9 seconds), the display will appear "0.8XX" figures, if the data found in the test is large, that is, 127um correct, and 420um If during the test you find that the data is too large, i.e. 127um is correct and 420um is too large for the diaphragm, you can increase the number (by using the "+" key), and vice versa, decrease the number (by using the "-" key). About every increase of 0.001, 420um or so, the number will be reduced by 2um accordingly, and then press the zero key to confirm. (The probe must be suspended)
3,Both the operation of one step and the end of the second step, should be recalibrated after the end of the operation.
Pay attention to the method of sensor plug. After switching on the instrument, press the probe onto the iron base and press the calibration button. Put the standard diaphragm (about 127um) on the iron base, if the measurement result is not about 127um, you can adjust it through the plus and minus keys. After the adjustment of the diaphragm about 127um, measure the diaphragm about 52um and 420um respectively to see whether it is within the allowable error range. If you find that all the film values are basically correct, then the calibration is successful.
What are the daily maintenance and repair methods of coating thickness gauge?
We all know that the coating thickness gauge is a kind of precision instrument, the thickness of the coating it measures to ensure error-free, then to ensure that the coating thickness gauge at any time can have a good working condition, routine maintenance and maintenance is essential. Elcometer coating thickness gauge agent experts for you to briefly introduce how the coating thickness gauge maintenance and maintenance.
First of all, to make the coating thickness gauge to keep clean, pay attention to heat and moisture, prevent contact with corrosive liquids or gases, and use is strictly prohibited to pull the probe line and arbitrary shaking. For a long time not to use the coating thickness gauge should pay attention to take out the battery, to avoid battery corrosion to bring damage to the instrument. Secondly, when loading the battery to confirm that the battery positive and negative contact is good, voltage is normal, measurement should pay attention to the use of the correct method. zui, if the coating thickness gauge failure is not good to disassemble it privately, we should return to the manufacturer or a professional maintenance organisation in time for maintenance.
