Preparing The Gauge For Test - Elcometer 508 Guia Del Usuario

5 PREPARING THE GAUGE FOR TEST

1 Fit the batteries, see Section 3.1.
2 Turn the crank handle anti-clockwise until
it is fully unwound.
3 Turn the coarse adjustment screw anti-
clockwise until it is fully unwound.
4 Zero the pressure gauge, see Section 5.2.
5 Select the measurement units; MPA
or PSI, see Section 3.3.
5.2 ZEROING THE DIGITAL PRESSURE GAUGE
1 Press
2 Fully unwind the crank handle and coarse adjustment screw
(anti-clockwise) to release all pressure.
3 Press MAX
maximum force recorded during test, known as 'Max Hold'.
Max Hold: The display holds the maximum value until the
is pressed for a second time. 'Max Hold' should be switched on before
undertaking an adhesion test, signified on the display by either
MAX
or PSI. The 'Max Hold' feature is switched off when the gauge is
switched off.
Note: "RLOCK" will be displayed if the gauge zero has failed. This is due to the
pressure not being fully released from the instrument. If this occurs,
release all the pressure by turning the crank handle followed by the coarse
adjustment screw anti-clockwise until fully unwound and press
repeat the gauge zero.
5.3 ATTACHING THE GAUGE TO THE DOLLY
1 Ensure the pin is pushed fully upwards towards the coupling.
2 Pull coupling sleeve up and insert pin into centre of dolly.
3 Release coupling sleeve.
The instrument should grip the dolly firmly. If the coupling does not grip the
4
dolly firmly, there may be excess adhesive in the centre of the dolly. Use
the dolly tool supplied to remove excess adhesive.
4 Turn the coarse adjustment screw clockwise to apply a small
amount of pressure (approximately 1 - 2MPa / 145 - 290psi),
until the coupling firmly grips the dolly.
