Operating Instructions

Power ON/OFF

To turn the meter ON or OFF press and hold the power button for 2 seconds.
Note: If the buzzer is enabled, there will be an audible beep when the

instrument is powered ON or OFF.

Measuring Procedure

Before each test session perform a Zero Calibration. See the Zero Calibration
section for details.

1. During start-up the meter begins an initialization process and enters
normal operation upon completion.

2. Select the closest reference lm to the estimated coating thickness
of the test area and perform a 2-point calibration on the appropriate
substrate plate.

3. Proceed with the 2-point calibration. See the Two-Point Calibration
section for details.

4.

Once the 2-point calibration has been completed, proceed with testing.

5. Select 3-5 measuring points on the test surface.

6. For each measuring point, it is recommended to take 5 measurements
and record the average value as indicated on the LCD display.

7. After each measuring point has been tested, the overall average value
should be noted as the coating thickness value of the test piece.

Note: Lightly press the sensor against the substrate being measured.
Keep the sensor in close contact with the surface of the substrate without
the use of excessive force as it can cause measurement errors. If the
measured value is greater than 1250μm and less than 1500μm, the LCD
displays "OL" indicating it is over the measurement range. If the measured
value is greater than 1500μm, the gauge will not respond.

Calibration Verification

While in normal operation, measure the standard coating thickness lm.
The measured value of the instrument should be within the indicated
accuracy on the coating thickness lm. If it is out of tolerance,
recalibration is required.

Note: If the calibration result is inaccurate try restoring the factory settings
and recalibrating.

Locking Screen Auto-Rotation

The instrument has a built-in gravity sensor, which automatically rotates
the display during testing. This feature allows users to read the measure­ment values in any direction. To lock the screen auto-rotation, hold the

arrow while in normal operation to turn auto-rotation function ON/OFF.

When disabled, the lock screen symbol

appears on the screen.
