Performing The Test - Elcometer AVU Gebrauchsanleitung

3 GETTING STARTED (continued)
3.2 SETTING UP THE ELCOMETER AVU
The procedure outlined below must be followed each time the
Elcometer AVU is switched on, prior to testing adhesion gauges.
1 Fit the appropriate dolly adaptor -
screwing clockwise to tighten into
position (Figure 1). The reading on
the Elcometer AVU display should be
zero.
 Do not overtighten as this will apply
pressure and result in inaccurate readings.
2 Connect an adhesion gauge or
actuator to the dolly adaptor
(Figure 2).
Elcometer 506 / 510 actuator shown.

3 Apply pressure until the reading on the
Elcometer AVU display is between
2 - 3.4 MPa (300 - 500 psi).
4 Leave the gauge pressured for a
minimum of 30 minutes to prepare the
Elcometer AVU for test and allow the
equipment to settle.
Note: The Elcometer AVU should be set up in an
operating environment of between
20°C to 25°C (68°F to 77°F).

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 Appendix A on page en-8 for recommended
test pressures for Elcometer pull-off adhesion gauges based on our
certification procedures. For other manufacturers' gauges, refer to the
manufacturers' specification.
a
The Elcometer AVU is supplied with an Elcometer 506 / 510 20mm dolly adaptor fitted. Dolly adaptors for other
adhesion gauges from Elcometer and other manufacturers, are available as optional accessories -
see Section 7 "Dolly Adaptors" on page en-6 for details.
