3. Please keep the sensor part clean and in good condition to avoid dust, oil and other factors affecting the measurement accuracy.
4. Do not use or store the gauge in high temperature, high humidity, flammable, explosive and strong magnetic field environments.
5. Clean the gauge casing with a soft cloth and mild detergent. Do not use abrasives or solvents to avoid damage to the gauge.
6. Do not disassemble or modify the gauge to avoid damage to it.
7. When the LCD displays the low battery symbol “03”, replace the battery in time. Remove the battery if it is not used for a long time.
8. The battery is normal “AA” alkaline battery, which cannot be charged.
9. The standard coating thickness sheet is a high-precision accessory, which is related to the accuracy of the gauge and needs to be preserved properly to prevent scratches, corrosion, bending and deformation of the surface.
10. The metal substrates are high-precision accessories, which are related to the accuracy of the gauge and need to be preserved properly to prevent scratches, rust, oxidation and deformation of the surface.
11. If an error occurred in the use of the gauge, please restore the factory settings and perform the two-point calibration.

Operating Instructions

A. Replace the battery:

1. Turn the locking screw on the battery compartment counterclockwise, open the battery cover, and install 2 batteries in the direction indicated in the compartment.
2. Install the battery cover and turn the locking screw clockwise.
3. The battery level is indicated by the battery symbol “ ” at the top right of the screen.

B. Power onloff:

1. Power on: Long press the ‘ ****button until the screen is on. If the buzzer is turned on, it will be accompanied by a power-on prompt tone.
2. Power off: Long press the **** button until the screen is off. If the buzzer is turned on, it will be accompanied by a power-off prompt tone.

C. Normal measurement

1. Long press the **** button to turn on the gauge. The gauge displays the initialization process, and enters the normal measurement mode after the initialization is completed.
2. Estimate the coating thickness of the measured object, and select the corresponding or close standard coating thickness sheet to perform the two-point calibration on the measurement substrate.
3. Selection of the substrate: A substrate with thickness or material close to the measured object and without coating should be selected as the measurement substrate as far as possible.
4. For the two-point calibration, please refer to the calibration section of the gauge.
5. After the two-point calibration, the coating thickness measurement can be performed on the measured object.
6. When measuring, select 3 to 5 measuring points on the surface of the measured object evenly, measure 5 times for each measuring point, and take the average value of the 5 times as the indicating value of the point.
7. After the indicating values of the 3 to 5 measuring points are measured, the average value of the values should be taken as the reference value of the coating thickness of the object.

Note:

1. Hold the gauge perpendicular to the substrate to be measured, and lightly press the gauge sensor against the substrate for measurement. It is necessary to keep the sensor in close contact with the surface of the substrate and avoid the measurement error caused by excessive force.
2. When the measured indicating value is greater than 1250um and less than 1500ym, the screen displays OL to indicate the over range.

zero calibration.
Two-point calibration| | On the basis of the zero calibration, stack a standard coating thickness sheet with known thickness and an uncoated substrate together for calibration to obtain a more accurate measurement result.

1. Zero calibration

1. Figure 1 appears on the screen, prompting users to place the gauge vertically on the uncoated substrate.
2. Lift it up after 2s. Zero will be displayed (as shown in Figure 2), and the gauge will automatically exit to the normal measurement mode.
3. At this point, the zero calibration is completed.

2. TWo-point calibration

1. Figure 3 appears on the screen. Stack a standard coating thickness sheet with known thickness (e.g.: 500 pm) and an uncoated substrate together for calibration.
2. Lift up the gauge after 2s and the measured value will be displayed (as shown in Figure 4).
3. Press the and buttons to adjust the value to the actual thickness of the standard coating thickness sheet (as shown in Figure 5).
4. Press the button to confirm the adjustment (or button to cancel the calibration).
5. Figure 6 appears on the screen, prompting users to place the gauge vertically on the uncoated substrate.
6. Lift it up after 2s. Zero will be displayed (as shown in Figure 7), and the gauge will automatically exit to the normal measurement mode.
7. At this point, the two-point calibration is completed.

3. Calibration verification
Measure the standard coating thickness sheet according to the above normal measurement mode. At this time, the indicating value of the gauge should be within the accuracy range of the nominal value for the standard coating thickness sheet. For example, if the nominal value for the standard coating thickness sheet is 100um, the indicating value of the gauge should be within +(1+3%H)um after calibration. If it is out of tolerance, recalibration is required.
Note: If the calibration result is inaccurate caused by incorrect operation, please restore factory settings and then recalibrate.
H. Auto rotatable screen
The gauge has a built-in gravity sensor, which automatically rotates the display during testing. it is convenient for users to read the value in any direction. The rotation angle is 0°, 90°, 180° and 270°. in the normal measurement mode, long press the button to tum on/off the rotary display function. When the rotary display is turned off, the lock screen symbol appears on the screen.
1. Data upload

1. Connect the USB cable to the computer and make sure the battery level of the gauge is sufficient.
2. Send real-time data or save the stored data to the computer and generate the report via the USB interface.

Note:
Regarding the use of the computer software, users can retrieve the Software User Manual from the Help option of the operation interface.
