Description
LR-Cal LCC 100 Description
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.
Typical Applications:
- Mobile and stationary pressure standard for low pressure and vacuum
- Mobile and stationary of all kind of pressure reading instruments
- Mobile and stationary pressure and vacuum source for calibration purposes
- Leak test
Standard scope of delivery:
- Pressure Controller LR-Cal LCC 100 with built-in Li-Ion battery
- Mains adapter 90...264 VAC
- 1 piece of transparent pneumatic hose/tube
- Factory certificate of calibration
- Operating manual

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 models LR-Cal LPP 08 and 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.
Operating Modes
LR-Cal LCC 100 Operating Modes
Measure
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.
Auto
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)
Control
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.
Leak Test
In the CTRL mode, connected test specimen can be tested to leakage / tightness by pressing the LEAK key.
