Product introduction
Coating thickness gauge is used for measuring the thickness of automobile
paint. The automotive body shell consist of metal materials such as iron and
aluminum and other non-metallic materials such as carbon fiber and plastic.
This coating thickness gauge can measure the thickness of car paint on iron
and aluminum materials. Moreover, it can identify not only non-metal car
bodies, but also the ferrous putty layer as well as the galvanized iron. This
coating thickness gauge uses low temperature resistant OLED as the display
interface to ensure that the display is still normal in the low temperature
environment of -40℃.

Zero adjustment
A zero-adjustment is required when using the gauge for the first time, after inserting new batteries, working with different materials or ambient temperature changes. Using iron-base and aluminum – base adjustment plates respectively to carry out zero adjustment. We strictly recommend carrying out the reference check on the uncoated original substrate, due to the difference of magnetic and conductive properties of the material, some measurement deviation will be caused. If this is not possible, please use the zero reference plates supplied by Linshang LS230 Coating Thickness Gauge User Manual technology, there are Fe plate and NFe plate, please choose correctly according to the measuring materials.
Measuring the plate or uncoated original substrate, a measured value will be displayed on the gauge, please make sure the probe tip is placed perpendicularly and evenly on the surface.
Hold the probe still, long press the button for 3s, the gauge will display
“zero reference place probe” (as shown in below picture).
After hearing a buzzer sound, the gauge will display “Lift off probe at least
15 cm” (as shown in below picture), release the button and lift the probe away
from the plate (substrate) for at least 15 cm.
The zero adjustment completed when there is the buzzer sound again, and the
LCD screen displays 0.0.
After the zero adjustment is completed, place the standard film on the plate (substrate), if the measurement value is stable and deviation from standard value within ±3μm, the gauge can be used normally.
Note: After the zero adjustment completed,when repeating measurement on the same spot, the reading may not always be 0μm, since surface roughness, dirt, scratches etc. It might cause variances. The operation of the gauge should be correct and proficient; otherwise, it will lead to instability of the measured values.
Measurement
- Use fingers to hold gauge where there is non-slip groove.
- Press the gauge vertically on the surface of the object to be measured. Keep the gauge steady and do not tilt or shake it. The result will be shown on the screen, and there will be a buzzer.
- To continue measuring, lift the gauge away from the object. Repeat the operation of step 2).
- When the device identifies the ferrous putty, the buzzer alerts for two times. And the interface of the device will prompt: “Ferrous putty”. When the device identifies the galvanized iron, it will turn on the green back light. The substrate is displayed as “FeZn”.
Check measurement records
In measurement mode, short press the button to check historical data. The
gauge stores 9 sets of data. When more than 9 sets of data are stored, the
earliest recorded value is automatically deleted, and No.1 is the last test
data. Recorded data will not loss after powering off.
