1 Ensure the pin is pushed fully upwards towards the coupling.
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 to repeat the gauge zero.
Rotate the knob on the front of the pressure
gauge to turn the red drag indicator to ‘0'.
3 Press to zero the gauge and set the gauge to store the
maximum force recorded during test, known as ‘Max Hold’.
2 Pull coupling sleeve up and insert pin into centre of dolly.
3 Release coupling sleeve.
5.3 ATTACHING THE GAUGE TO THE DOLLY
1 Press to switch the gauge on.
To zero the digital pressure gauge:
2 Fully unwind the handle (anti-clockwise) to release all pressure.
Max Hold: The display holds the maximum value until the button
is pressed for a second time. ‘Max Hold’ should be switched on before
MAX
undertaking an adhesion test, signified on the display by either MPA
MAX
or PSI. The ‘Max Hold’ feature is switched off when the gauge is
switched off.
4 The instrument should grip the dolly firmly. If the coupling does not grip the
dolly firmly, there may be excess adhesive in the centre of the dolly. Use the
dolly tool supplied to remove excess adhesive.
To zero the analogue pressure gauge:
2 Zero the pressure gauge, see Section 5.2.
5.1 PREPARING THE GAUGE FOR TEST
3 Select the measurement units; MPA or PSI (digital pressure
gauge only) - see Section 3.3 on page en-4.
1 Turn the handle anti-clockwise until it is fully unwound to release
any pressure in the tester.
