3.1.3 Connecting the pressure measuring instruments (reference and test
specimen)
■ The pressure connections have G ½ female threads.
When you are calibrating devices with different connection threads,
please use appropriate threaded adapters (see chapter 9. Acces-
sories).
■ Before connecting the reference pressure instrument and test item, the system
should be vented. For this, oil is pumped into the system by opening the pressure
connections by carefully turning the star handle in a clockwise direction. It should be
turned until oil appears at the o-ring seals of the open pressure connection and no
more air bubbles are escaping. The shut-off valve on the reservoir must be closed
and any shut-off valves for the test conection installed must be opened.
■ Connect the reference pressure measuring instrument and the instrument to be
inspected (test specimen), one to each of the CPP1000-M/-L two pressure connec-
tions. The pressure connections are free-rotating, so that you can align the instru-
ments in such a way that a proper reading is ensured. An O-ring seal is already
fitted, so no additional sealing material is required. Hand tightening is sufficient to
make a proper seal.
■ To calibrate instruments with back mounting connection there is an angle connec-
tion 90° available (see chapter 9. Accessories).
Check the O-ring seal in the pressure connections for proper
seat and for any wear. Replace, if necessary (See chapter 9.
Accessories). Please see to it that each instrument mounted
to the test pump must be clean inside.
