4 PERFORMING THE TEST (continued)
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 the adhesion gauge or
actuator to the dolly adaptor (Figure 2).
 Elcometer 506 / 510 actuator shown.
3 "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.
 The display will hold the maximum value
until the 'MAX' softkey is pressed again.
4 Apply pressure until the required test
pressure is reached on the adhesion
gauge and compare the adhesion
gauge's reading with the reading on
the Elcometer AVU display - see
Section 5 "Assessing the Results" on
page en-5.
5 To switch between measurement
units, press the "MPa/psi" softkey.
The Elcometer AVU will provide adhesion readings for 20mm dollies
irrespective of which dolly adaptor is fitted - see below for additional
information.
ELCOMETER 506 / 510 DOLLY ADAPTOR FOR
50MM ACTUATOR SKIRT (Part Number: T99923936)
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.

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.
