7.8 APPLY PRESSURE TO THE FOLLOwER

Apply slight downwards pressure onto the top of the follower using the charging tool.

This part of the test takes one minute and the screen indicates this time period by a series of >>>

moving across the screen.

At the end of the time period, the equipment will beep and the "Fit Probe" screen is displayed.

7.9 FIT THE PROBE TO THE BARREL

Using heat-protecting gloves, screw the probe onto the top of the barrel and secure the large nut

hand tight.

Press the green GO key to indicate that the probe has been fitted. The "Pre-Conditioning" screen will

then be displayed.

Note that the gas will be automatically switched to full pressure to perform the test. The gas pressure

inside the barrel is displayed on this screen.

If the required gas pressure is known (testing a sample with a "known" IV), then the pressure can be

checked and altered at this stage.

If the pressure is too low, increase it using the pressure regulator on the right hand side of the equipment.

If the pressure is too high, rotate the pressure regulator on the right hand side of the equipment

anti-clockwise, press the key under GAS OFF to release the pressure then press the same key (now

labelled GAS ON) to re-apply the pressure. Finally, increase the pressure, using the pressure regulator,

to give the required value.

Note that if the GO key is not pressed within one minute after the "Fit probe then press GO" message

is displayed, then the test will end and the warning screen below will be displayed.
