Press the and arrows to set the tolerance value, and press the button to confirm. Use the gauge to measure the coating thickness of the measured object. The screen displays the measured value and whether or not the thickness passes or fails ("PASS" or "FAIL"). button to return to the single-point analyzing setup Press the button to exit and resume normal operation.
Zero Calibration While in normal operation press and hold the button to enter the selected calibration mode from the Setup Mode. See Setting Calibration Mode for details. OK MENU Calibration Mode Icon ZERO Description Zero Calibration Simply place the sensor on an uncoated metal substrate for zero calibration. Two-Point Calibration Place a standard coating thickness film OK with a known thickness on an uncoated ZERO substrate for calibration to obtain a more accurate measurement result for testing.
Two-Point Calibration 1. When Figure 3 appears on the screen, place a standard coating thickness film with known thickness (e.g.: 500μm) on top of an uncoated substrate. 2. Place the gauge vertically on both the thickness film and uncoated substrate. 3. Lift the instrument after approximately 2 seconds and the measured value will be displayed (as shown in Figure 4). 4. Press the and arrows to adjust the value to the actual thickness of the standard coating thickness film (as shown in Figure 5). 5.
Calibration Verification While in normal operation, measure the standard coating thickness film. The measured value of the instrument should be within the indicated accuracy on the coating thickness film. 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.
Battery Replacement When the " " icon appears on the LCD, the batteries should be replaced. 1. Remove the screw with a Philips screwdriver and open the battery cover. 2. Replace the 2 x "AA" batteries. 3. Secure the battery cover back and tighten the screw.
