The LR-Cal LCC 100 pressure controller measures and generates pressure and vacuum and consequently it is more than a mere measuring instrument - it can also be applied as test and calibration instrument for pressure sensors, pressure swithes and pressure gauges. Thanks to internal pressure/vacuum generation no auxiliary tools are required for operation. An internal Li-Ion battery (chargeable) makes mobile operation very easy.
Parallel operation of mains and battery supply allows for maximum flexibility.

The integrated electrical pump can make max. -600 mbar vacuum. If a larger vacuum is required, an external vacuum source is needed, e.g. the pressure test pump LR-Cal 2941.
The LR-Cal LCC 100 can make up to -10% of full range value as vacuum. If you have to measure/controll larger vacuum values, you can do this by exchaning the +/- ports.
The measuring mode ("MESS") is used to measure a gauge or differential pressure. In this operation mode the internal pump of the LR-Cal LCC 100 is deactivated. The applied pressure, measured by the internal reference sensor, is shown on the display.
The control mode ("CTRL") is used to calibrate pressure transmitter, pressure switches or pressure gauges. In this operation mode the internal pump of the LR-Cal LCC 100 is activated, the pressure is adjusted to the set point. The pressure value is shown on the display.
In the "AUTO" mode, a calibration procedure can be defined. This mode allows a comfortable calibration of several test specimen with same specifications. The calibration can be run AUTOmatically in this mode.
Following graphic shows the principle of a calibration procedure:
(1) Wait for start command (pressing OK key)
(2) Delay time (adjustable)
(4) Duration of ZERO balancing of the system
(7) Dwell time at ZERO point
(9) Adjustment time to the next step
(10) Dwell time
(13) Delay time at max. pressure step
(15) Adjustment time to the next step
(16) Dwell time at ZERO point
(18) Delay time (adjustable)
