How to Use Paint Thickness Gauge?

There are various paint thickness gauges on the domestic and international markets. The operation methods differ from different brands. The paint thickness gauge is mainly used in the automotive industry. Today, we take the Linshang LS220B paint thickness gauge as an example to introduce the operation method of the paint thickness gauge. The operation method is as follows:
          1.Scan the QR code on the LS220B paint thickness gauge user manual to download and install the mobile phone app.
          2.Open the APP and display the “Linshang” logo for 3 seconds. If there is no bound bluetooth device, then enter the bluetooth setting interface.Click "(Start Search)", prompt "(Searching for device...)" and list the available bluetooth devices that are searched; click the "(Stop Search)" button to stop searching for Bluetooth devices and the search indicator icon disappears. Selecting "LS" + gauge serial number will bind the selected gauge (prompt: each gauge has a unique serial number).
          3: If the APP has a bound bluetooth device, the logo interface will appear for 3 seconds then automatically search and connect the bound Bluetooth device. When the connection is successful, it will automatically enter the “(Measurement)” interface and display the information read by the gauge.
