Description

LR-Cal LDM 70-K50 Description

The display is continously rotatable so that a clear readability is garanteed even in unusual installation positions. The LR-Cal LDM 70-K50 can be operated menu-driven via three push-buttons. Besides showing information about the nominal pressure range as well as minimal and maximal pressure of the process, several pressure units (psi, bar, mbar, mWC, inHg, cmHg, mmHg, kPa, MPa) and the position of the decimal point can be set. The instruments zero and span can be calibrated, and the LR-Cal LDM 70-K50 can be set to factory default values via menu.
