Considerations The measurements in the conectors must be with the screws properly tightened, in this way we can assure a good connexion. The load cell has 4 basic wires, 2 of them are for power supply (+Vexc y -Vexc) and the other two for the output signal. The signal in mV, changes proportionally to the effort applied to the load cell and to his power supply. E.g a 2mV sensitivity cell with 10V in Vexc, will give you 20mV for an effort equivalent to his scale. How to check it 1.- Check that the auxiliar supply of the converter is … Continúa leyendo How to check a load cell and his converter
To check the PT100, the probe must be unpluged from the installation.
