Conversions and Changes The device may not be modified in terms of design or safety without the express consent of Lorenz Messtechnik GmbH. Any modification excludes any liability on our part for damages resulting there- from. Repairs and modifications are prohibited. CE Marking With the CE marking, Lorenz Messtechnik GmbH guarantees that its product meets the requirements of the relevant EC directives. Preamble Product Description The LCV-USB3 is a measurement amplifier for the conversion of analog signals into digital measured values. These measured data can be requested through the Computer via the USB-interface. -
Page 7: Safe And Correct Use
If the LCV-USB3 is calibrated together with the sensor, you can take the output values from the test certificate. If the LCV-USB3 is calibrated without a sensor, you can take the output values as described above. In this case, they are pre-calibrated with a high precision source. -
