Attaching The Gauge To The Dolly - Elcometer 506 Guia Del Usuario

4 PREPARING THE GAUGE FOR TEST (continued)
4.1 ZEROING THE ANALOGUE PRESSURE GAUGE
1 Fully unwind the crank handle and coarse adjustment screw
(anti-clockwise) to release all pressure.
2 Position the red drag indicator to "0" by rotating the knob on the
front of the dial indicator.
4.2 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
zero.

5 ATTACHING THE GAUGE TO THE DOLLY

1 Ensure the quick connect coupling is fully
depressed.
2 Pull up the quick connect coupling, place
the actuator (with skirt fitted ) over the
dolly then release the coupling to grip the
dolly.
 The quick connect coupling is not a bayonet
fitting. Do not attempt to push the actuator on to
the dolly without lifting the quick connect
coupling.
3 Turn the coarse adjustment screw clockwise to apply a small
amount of pressure (approximately 1 - 2MPa / 145 - 290psi), until
the actuator firmly grips the dolly.
