Eliminating the possible zero point drifting can be done by using the zeroing push button and the led on the board. Before this zero point setting the transmitter must be disconnected from the process by closing the valves and the pressure difference between the inputs must be eliminated. The maximum value of ± 10 % of the range can be set to the zero. Bigger drifting will be considered as a sensor fault.1. Close the process connections. 2. Open the valve between the measuring con- nections.1. Close the process connections. 2.
