2.6.7 Limits
Set up
The user can set high and low predicted cured thickness limit boundaries for their quality
control process. If a measurement is taken which falls outside these limit boundaries then the
gauge displays a warning error message.
In addition to setting limits the Elcometer 550 Non-Contact Uncured Powder Gauge features
powder shrinkage compensation. This adjustment is known as the percentage distortion
setting and allows users to ensure that the predicted coating thickness value is equivalent to
the actual coating thickness post cure.
To calculate the percentage distortion value:
• Measure a powder coated test panel using Elcometer 550 Non-Contact Uncured Powder
Gauge and record the gauge's predicted coating thickness value. Cure the test panel in
the powder oven for the appropriate time and temperature for the powder coating
