Rel. 20220203

Genera�on of test pressure up to +25 bar (363 psi), switchable togenera�on of vacuum down to -0,9 bar (-26.6 inHg)
The LR-Cal LAP-P electric calibra�on test pressure pump is used for simple
pressure genera�on (without manual eﬀort) for checking, adjus�ng andcalibra�on of mechanical and electronic pressure reading instruments by meansof compara�ve measurements.
When the measuring instrument to be checked and a suﬃciently accurate reference
instrument are connected to the LR-Cal LAP-P electric calibra�on pressure test pump,
the same pressure acts on both measuring instruments when the pump is actuated.
By comparing the two measured values at any pressure values, the accuracy of the unit under test can be checked oradjusted.
Due to the integrated electric pump, the LR-Cal LAP-P allows an automa�c and exact pressure genera�on with thepossibility to switch to vacuum genera�on. For precise adjustment of the test pressure the LR-Cal LAP-P electriccalibra�on pressure test pump is equipped with a ﬁne adjustment valve. Both, the test specimen and the referenceinstrument are mounted on top of the electric calibra�on pressure test pump, if necessary using suitable thread
adapters (see Accessories / Adapter sets on page 3). No tools are required for connec�ng the unit under test andreference instrument, hand-�ghtening of the instruments is suﬃcient.

VRS-G12

Volume reducer for LR-Cal TLDMM 2.0 and LR-Cal LDM 80

LPP-VOLUMEN-TOOL Tool for the ﬁne adjustment valve, to increase the diameter,thus even easier ﬁne adjustment of the test pressure.
Material: aluminum. Simply plug it on the pressure ﬁne adjustment valve.

Please note that the performance of the LR-Cal LAP-P electric calibra�on pressure test pumpdepends on the volume of the calibra�on circuit. The smaller the volume, the be�er theperformance. You can keep the volume of the calibra�on circuit small or minimize it by dispensing
with hose lines or pressure hoses and using a reference device with the smallest possible volumein the pressure connec�on.
For the LR-Cal TLDMM 2.0 and LR- Cal LDM 80 reference instruments listed on page 4, forexample, we recommend using the op�onal volume reducer, order-code VRS-G12.

Typical performance of the electric pump LR-Cal LAP-P:
Pressure: 0 to 20 bar: <85 seconds(The ﬁnal value of 25 bar is most easily achieved if you ﬁrst turn the ﬁne adjustment
valve quite far out (an�-clockwise), electrically generate pressure up to approx. 20 bar
and then screw the ﬁnd adjustment valve in clockwise.)Vacuum: 0 to -0,9 bar: <8 seconds
