The EiUK LCC 100measures 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 switches and pressure gauges.
Thanks to the 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.

Operating modes
LCC 100 Operating Modes
MEASURE
The Measuring mode is used to measure a gauge or differential pressure. In this operation mode the internal pump of the EiUK LCC 100 is deactivated. The applied pressure, measured by the internal reference sensor, is shown in the display.
CONTROL
The Control mode is used to calibrate pressure transmitter, pressure switches or pressure gauges. In this operation mode the internal pump of the EiUK LCC 100 is activated, the pressure is adjusted to the set point. The pressure value is shown in the display.
Leak Test
In the Control mode, connected test specimen can be tested to leakage / tightness by pressing the LEAK key.
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 graph shows the principle of a calibration procedure:
Steps:
[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 for next step
[16] Dwell time at ZERO point
[18] Delay time (adjustable)
