When using the Elcometer 506 Analogue Adhesion Tester with 50mm dolly adaptor, the reading on the
Elcometer AVU display should be compared with the reading on the 20mm scale of the Elcometer 506
analogue pressure gauge.
When using the Elcometer 506 Digital Adhesion Tester with 50mm dolly adaptor, the dolly size should be
set to 20mm before test - refer to the Elcometer 506 User Guide for instructions on how to select the

When testing the Elcometer 106 Pull-Off Adhesion Tester with the Scale 6 dolly adaptor, the Elcometer
AVU reading should be multiplied by a conversion factor of 6.4516 before comparing with the adhesion
gauge reading.
For other manufacturers' gauges, please refer to the manufacturers' instructions for adhesion readings
using 20mm dollies.
