Item number references in the following text, (1), (2), etc, relate to the
hydraulic system schematic, shown in the figures below.
Place the unit onto a clean, flat surface of a strong and rigid workbench.
Ensure that the front of the unit is approximately ¾" / 20 mm from the front edge of the
bench to allow the ram screw capstan to overhang and freely rotate.
Level the DWT by placing the spirit level on top of the weight carrier tube and adjusting
the 4 leveling feet accordingly.
Fill the fluid reservoir as follows:
Fully unscrew (counter-clockwise) the reservoir valve screw (3) and remove it together
with the spring and reservoir cover. Place to one side. Fill with the correct fluid to the top
of the brass nut visible on the inside of the reservoir. Fully wind out (counter-clockwise)
the capstan so that fluid is drawn into the DWT. Refill the reservoir to the top of the brass
nut and replace the cover, spring and reservoir valve screw. Fully screw in (clockwise)
the reservoir valve screw and then unscrew (counter-clockwise) again 4 full turns.
The deadweight tester is now ready to receive the Equipment Under Test (EUT).
