Roughness meter repair


Let's talk about the repair of the roughness meter below.


(1) Strictly avoid collision, severe vibration, heavy dust, moisture, oil, strong magnetism, etc.


(2) Please store the sensor in the box in time.


(3) When the battery voltage is insufficient, it should be charged in time. It is allowed to insert the power adapter at the same time, but testing the sample with lower Ra value will affect the test accuracy. If the voltage is still insufficient or full after a few hours of charging and it is found to be insufficient for a short time, the battery needs to be replaced.


a. Unscrew the two screws on the battery compartment cover and remove the battery compartment cover.


b. Remove the battery pack, unplug the connector, and quickly replace the spare battery pack (optional).


c. Put the battery pack back into the battery compartment, close the battery compartment cover, and tighten the screws.


When the battery is replaced, it will cause loss of data stored in the machine, so important measurement data should be printed or recorded first.


(4) Because the sensor is very rigorous, the disassembly and assembly operation will be damaged if it is accidentally damaged. Therefore, it is recommended to use it in the measurement to minimize the number of disassembly and assembly, so as not to affect the maintenance and repair of the roughness meter.


(5) When the measurement error exceeds the range of ±10%, and the user confirms that the cause of the error is not caused by human factors, the machine-specific software calibration function can be used. The calibration value is a percentage that represents the percentage of increase (or decrease) in the measured results after calibration relative to uncalibrated.


For example, the Ra value of a workpiece surface calibration is 0.44 μm, while the actual measurement value is 0.40 μm at a 0.8 mm sampling length. At this time, the calibration value of the corresponding sampling length (ie 0.8mm) can be adjusted to +10% in the "System Settings" menu. Further measurement was carried out, and the Ra value was measured to be 0.44 μm.


After the calibration value is specified, all the measured roughness parameters (including the Tp value) will increase or decrease by the specified percentage, and the calibration value will remain valid for the measurement result of the corresponding sampling length until the calibration value is changed. .


(6) When an abnormality occurs, the user can try to repair without disassembling the machine. If it cannot be repaired, please send it to the maintenance department. Users should not disassemble the machine themselves, so that the company can check the maintenance and repair of the roughness meter.
