4 PERFORMING THE TEST

The Elcometer AVU is designed to provide users with a method of verifying the performance of their
pull-off adhesion gauges .
The performance of an adhesion gauge should be verified at a number of test pressures. Refer to
Section 9 on page 7 for recommended test pressures for Elcometer pull-of f adhesion gauges based on
our certification procedures. For other manufacturers' gauges, refer to the manufacturers' specification.
1 Press and hold the "On/Off" (
Elcometer AVU.
2 Fit the appropriate dolly adaptor - screwing clockwise to
tighten into position. The reading on the Elcometer AVU
display should be zero.
Note: Do not overtighten as this will apply pressure and result in
inaccurate readings.
3 Connect the adhesion gauge or actuator to the dolly adaptor
(Elcometer 506 actuator shown).
4 "MAX" should be displayed on the Elcometer AVU LCD to
indicate that 'Max Hold' is switched on. 'Max Hold' holds the
Elcometer AVU reading when the required test pressure has
been reached on the adhesion gauge. Press the "MAX"
softkey to switch 'Max Hold' on and off.
Note: The display will hold the maximum value until the 'MAX' softkey is
pressed again.
