LPP 08
1. Safety instruc ons
Read these opera ng instruc ons care-
fully prior to opera ng the pressure test
pump.
Ensure that all pressure connec ons have
been established correctly.
2. Product descrip on
The pressure test pump
generate pressure for checking, adjus ng and
calibra ng mechanical and electronic pressure
measuring instruments by compara ve
measurements in the low-pressure range. These
pressure tests may be carried out in laboratories,
workshops or on site at the measuring point.
If the instrument to be tested and a sufficiently
accurate reference measuring instrument are
connected up to the pressure test pump
LR-Cal LPP 08, the same pressure (or vacuum) is
applied to the two measuring instruments when
the pump is operated. By comparing the two
measure values at random pressure values, the
accuracy can be verified or the instrument under
test can be adjusted.
The LR-Cal LPP 08 is a pneuma c pressure test
pump for low-pressure ranges up to 8 bar with
change-over switch to vacuum genera on down to
-850 mbar. Despite its compact dimensions, the
pressure test pump LR-Cal
operate and allows for exact genera on of the
required test pressures. The maximum pressure or
vacuum achievable depends on the a ached test
volume. The smooth-running pressure genera on
and the integrated fine adjustment valve allows a
safe and precise se ng of very small posi ve
respec vely nega ve pressure values in the range
of mbar.
The test device and the reference instrument can
be easily connected by means of a supplied T-
connector with tube connec ons.

3. Moun ng instruc ons
Mount the T-connector (5) to the 1/8" BSP female
thread of the pump body (7). Sealing by means of
o-ring. Max. torque is 15 Nm.
Plug both hoses (2) and (4) into the connectors of
the T-piece (simply plug-in; release by opera ng
the blue ring). To the open ends of the hoses, plug
the both connectors with 1/8" BSP male thread at
the other end (simply plug-in; release by opera ng
the blue ring).
Mount the reference adapter (1) to your reference
instrument (sealing by means of o-ring).
Mount the device under test adapter (3) to your
instrument under test (sealing by means of o-ring).
If neccessary, use op onal thread adapter (see
accessories: LPP-ADAPTER-BSP for set of BSP
adapters, LPP-ADAPTER-NPT for set of NPT
adapters, LPP-ADAPTER-M for set of metric and
MINIMESS 1620 adapters).
Connect reference instrument and device under
test with mounted connectors to the both open
ends of the hose (simply plug-in; relase by
opera ng the blue ring).
