3. Commissioning and Operation .
3.1 Preparation
.
3.1.1 Setting up the Device .
Set up the pressure balance on a solid surface. If it is not resting on a solid foundation or is
subject to vibrations, measurements could be affected. This should be avoided.
If no temperature control system is present, the device should at least not be placed near a heat
element or window. This will reduce drafts and warm air flows as much as possible.
The water level should be used to align the device. At this time, rough alignment can already be
performed without the piston/cylinder system. Using the rotating feed, position the device so that it
is horizontal.
The oil container may need to be filled, or refilled (volume 250 ml). For this purpose, the locking
screw with the oil filling symbol on top of the basement must be opened. Special oil must be used
for refilling (1 litre supplied, or available as accessory). The system must be vented before initial
filling, or after a complete oil change. For this purpose, please proceed according to section 5.3.3.
The protection film on the screwed drain plug of the oil container need to be removed before
operating (coverage of the ventilation hole during transportation).
Screw the handle bars of the star handle onto the spindle pump.
We recommend unscrewing the spindle pump completely when you start to record measurement
values, (turning anticlockwise) to allow enough volume for measurements. The low-pressure and
high-pressure shut-off valve must be opened during this process.
