To calibrate the SEALEY TA090.V2 Paint Thickness Gauge, you have several options depending on your specific needs:
1. Basic Calibration: This method is recommended for measurements on even surfaces and when the measuring object has the same material, size, and curvature as the zero plate attached in the casing.
2. Zero-Point Calibration: This method is recommended if measurement errors of up to ±3% of reading plus a constant error of the probe are permitted. Place the probe on an uncoated sample (zero coating thickness) ensuring it is vertical and stable. Press and hold the 'Zero' button for about 1.5 seconds until the LCD displays 0.0 um.
3. One-Point Calibration: This method is recommended for high precision measurements and when readings are expected to be close to the calibration value. Lay the calibration foil on an uncoated sample, apply the probe, and wait for a steady reading. Remove the probe and adjust the reading using the UP or DOWN keys to match the foil thickness.
4. Two-Point Calibration: This method is recommended for measurements on rough surfaces or for precise measurements on smooth surfaces. It requires the use of two different calibration foils. Perform a zero-point calibration, then lay the first foil on an uncoated sample and adjust the reading. Repeat the process with the second foil.
It is important to clean the measuring point before calibration and ensure the calibration sample matches the product sample in terms of curvature radius, substrate material properties, substrate thickness, and size of the measuring area. The gauge will automatically calculate the mean calibration value based on multiple readings.
