A film thickness meter is an instrument used to measure the thickness of a film or coating, also known as a film thickness meter. It can measure the thickness of the film or coating, so that the quality of the material can be evaluated and controlled.

Common problems and solutions
Instrument readings inaccurate: inspection instrument calibration and calibration of the situation, whether to need to recalibrate or calibration; Check the preparation of the sample surface, such as whether there are oxides or impurities, etc. Check whether the probe and measuring method of the instrument are correct, select the appropriate probe and measuring method; Ensure that the instrument of temperature and humidity conditions meet the requirements.

Common problems and solutions of film thickness instrument

Unstable instrument reading: check the environmental conditions of the instrument reading, such as whether there are interference sources, whether there are radiation sources, etc., should be away from interference sources; Check whether the instrument probe and measurement method are correct, adjust the probe and measurement method to improve the measurement accuracy; Check instrument power supply situation, to ensure stable power supply.

Instrument malfunction: inspection instrument for appearance damage or parts damage, such as whether there is a loose connector or probe damage; Check the power supply of the instrument, whether there is a power problem; See if there are internal components damaged, such as the need to replace parts or repairs, should contact professionals for processing.

Instrument shows there are residual data or letters on the screen: clean the instrument display screen, use special cleaner or cloth to wipe the screen.

Common problems and solutions of film thickness instrument

Instrument reading is too large or too small: check whether the probe is tilted or placed uneven, adjust the position of the probe; Check whether need to replace the probe because the probe damage can also affect reading.

Instrument drift: check whether the instrument is running in the right environment, such as temperature and humidity; Check the probe for damage or damaged wiring and repair or replace it; Recalipay the zero point of the instrument to ensure the zero point is accurate.

Measurement deviation of the instrument: check whether the instrument needs to be calibrated, if so, follow the instructions of the operation manual; Check whether the connector of the probe is loose or needs replacing; Check whether there is interference source and keep it away from interference source; Check whether the sample surface is in normal condition, if the sample surface needs to be reprocessed; Check whether the size of the probe and measuring method is suitable for the samples.

Other instrument failures, such as noise, abnormal display, etc. : contact the manufacturer or maintenance personnel for inspection and maintenance in time.

Notes
Before using film thickness gauge, read manual carefully and understand the use of the instrument and matters needing attention.

During the measurement, ensure that the sample surface is prepared to meet the requirements to avoid affecting the measurement accuracy.

Calibration and calibration of the film thickness meter are carried out regularly to ensure the accuracy of the measurement results.

Keep the instrument clean and maintained to avoid dust or dirt affecting the instrument.

When using film thickness gauge should pay attention to safety, ensure the safety of the operator.

In conclusion, in order to maintain the accuracy and stability of the film thickness meter, we need to carry out regular calibration and calibration, and follow the instructions in the operation manual for correct operation. If there is a fault, it should be dealt with in time to ensure the normal use of the instrument.
