The PV Input (Zero) refers to a known standard such as zero pressure (e.g.: vent both

eliminate the error at the zero reference. The slope (angle) of the response is unchanged.

Input (Zero) now.
8. Verify that the value of the PV applied at the input is exactly Zero. Then click OK to send
the Correct Input (Zero) command to the Transmitter, which adjusts the input calibration.
9. Wait for the message Sensor input has stabilized, then click OK.
10. When the zero correction is complete, the message Sensor zero succeeded! is displayed;
