Description

LR-Cal LCC 100 description

The LR-Cal LCC 100 pressure controller measures and generates pressure and negative pressure (vacuum) and can thus be used both as a reference pressure gauge and as a calibration device for pressure sensors, pressure switches and pressure gauges. Due to the internal pressure generation, no further accessories are required for operation. For mobile use, the LR-Cal LCC 100 is equipped with an internal lithium-ion battery. Parallel operation of mains and battery supply is possible without any problems and ensures the highest possible flexibility.

Typical applications:

Mobile and stationary reference pressure gauge for small pressures and vacuums
Mobile and stationary calibration of pressure and vacuum gauges of all types
Mobile and stationary pressure and vacuum controller for sensor calibrations
Density and leakage test

Notice:
The LR-Cal LCC 100 generates negative pressure (vacuum) in the amount of max. 10% of the positive pressure measuring range end value. If measurement and control is also to be performed in the negative range up to -100% of the final value, the (+) and (-) connections must be interchanged.
The integrated electric pump can generate max. -600 mbar negative pressure (vacuum). To generate higher negative pressures, we recommend an external manual vacuum pump, e.g. LR-Cal LPP 10 or LR-Cal 2941.

Operating modes

LR-Cal LCC 100 operating modes

Mode: MEASURE

The MEASURE mode is used to measure a differential or relative pressure. The pressure pump of the LR-Cal LCC 100 is not active in this mode. The pressure is measured directly by the internal reference sensor and displayed.

Mode: CONTROL

The CTRL mode is used for the calibration of pressure sensors, pressure switches and other pressure measuring devices. In CTRL mode, the pressure pump of the LR-Cal LCC 100 is active and regulates the set pressure accordingly. The pressure value is brought to the display.

Mode: AUTO

In AUTO mode, a pressure profile can be stored. This is particularly useful if several pressure gauges are to be calibrated with identical pressure values. In addition, this mode makes it possible to run a defined profile several times in succession.

The following figure shows a flow chart for the AUTO mode:

Mode: LEAK TEST

In CTRL mode (Control mode), connected DUTs can be checked for leaks using the LEAK button.
