Layer Thickness Gauge Troubleshooting
Coating thickness gauge is a non-destructive for a variety of metal materials for the detection of the thickness of the coating of the exterior instrument, the user in the process of using, sometimes there will be some abnormalities presented, these abnormalities sometimes we can deal with, based on the application of the coating thickness gauge experience over a long period of time, the following we will say that the coating thickness gauge common faults and methods of disposal.
1. Instrument measurement is not allowed
① Please calibrate the instrument first system, calibration, so that it fits the error range. Error compliance ≦ 3% (thickness value), such as the need to test the more in the workpiece to be measured on the lubricated bare base (uncoated substrate) to stop the system calibration.
② please check whether the probe front wear, whether deformation, there are attached substances, etc., the probe sheath is not in the degree, etc., deformation can be appropriately corrected with sandpaper sanding, disposal of clean.
③ The effect of roughness of the substrate surface of the measured parts, causing systematic and occasional errors, measurements in different locations to increase the number of measurements, restraining occasional errors. Or use sandpaper to polish the substrate to recalibrate the zero point of the instrument.
④ Measurement techniques and probe placement, the test time to adhere to the probe and the specimen vertical
⑤The curvature of the tested piece, under the radius of curvature that the probe is compatible with, recalibrate. Especially the convex surface of the pipe.
Pay attention to the probe V slot stable placement.
2. Instrument does not switch on
① Please check whether the battery can have power, or replace the battery with a new one.
② Please check whether the battery contact is good, and the electrode is not oxidised or rust (such as rust can be used to scrape off the oxide layer).
③ Please check whether the key can be pressed into place, and the key is normal and flexible.
Other host line problems, consult the company's after-sales service or return to the factory for repair.
3. Measure no data change
① Probe can be well connected probe can be damaged, etc.
② related host line faults.
4. Instrument can not measure
① Check whether the probe can be well connected, inserted in place.
② check whether the probe line can be broken in the centre, focus on checking the probe connector (joints can be unscrewed to view the knob)
③ probe frequently used in large quantities, sensor aging or damage, burns, etc.
④ other host line component problems
