Commissioning, operation
5.1
Unpacking the hydraulic comparison test pump
As soon as possible after delivery open the packaging of the hydraulic comparison test pump and
check that you have all the items detailed in the packing list (see chapter 3.2 “Scope of delivery”). As
you are unpacking the items, examine them for signs of damage or breakage during transit.
If any items are missing get in touch immediately with DH-Budenberg/WIKA to inform us of the
shortage.
5.2
Environmental requirement
When siting the hydraulic comparison test pump not in a temperature controlled laboratory, look for
an area that satisfies the following criteria as much as possible:
■
A constant temperature area free from draughts and sources of heat or cold
■
An area free from noise and vibration, constantly used pathways
■
A clean dry area free from corrosive liquids or vapours
A strong, stable, level table or workbench with the capability of supporting the system with sufficient
space to operate is required.
5.3
Assembly of base units Fastening base to bench
The base is to be mounted on a firm, level table or bench about 0.9 m high. The centre line of the
front adjustable feet of the unit should be about 40 mm from the front edge of the bench to allow
adequate clearance for the handwheel.
1.
Mark the position of the adjustable feet of the unit on the top of the bench.
2.
Position a level plate at the centre of each of the adjustable feet of the unit and screw the plate to
the bench to ensure that the hydraulic comparison test pump is rigid.
3.
Fit the base unit on the bench with the adjustable feet on the level plates and the handwheel
shaft projecting over the front of the bench.
4.
Screw in the four handwheel spokes into the hub.
5.
Using the spirit level provided, level the test pump by adjusting the four knurled feet.

Connection of the test item and the reference measuring instrument
The instrument to be tested and the reference measuring instrument are inserted into the two test
connections and can be oriented. It doesn’t matter which port is used for which instrument.
Information
To calibrate instruments with a rear-mount connection, an angular connector is
available as an accessory.
