Page 2 of 15 1. General Description: The Gneuss pressure measurement amplifier type DMV 4000 is a measurement amplifier for pressure transducers with strain gauge technology. Universal setting possibilities guarantee that all pressure transducers with 1 to 4 mV output signal can be connected. Furthermore, three freely-adjustable limit contacts and one optional analogue signal 0-10 V, 0-20 mA or 4-20 mA can be processed.
Pressure Measurement Amplifier DMV 4000 Page 3 of 15 Assembly: The instrument is designed for panel assembly. It is to be assembled in such a manner, as to protect it from humidity, dirt and vibration. The ambient temperature is not to exceed 50 ° C.

Listed below is a step-by-step breakdown for start-up and commissioning purposes. In order to warrant an exact measurement, the connected pressure sensor needs to be calibrated in conjunction with the DMV 4000. During the calibration procedure, the pressure sensor must be at operating temperature and not subjected to any pressure influences.

Adjustment levels (see Tables on pages 5 and 6). By repeatedly activating the button the DMV 4000 switches from operating mode to calibration mode alternatively to Parameter mode (Par) and to configuration mode (Conf). On pushing again the instrument is set back to operating mode.
