The zero pressure migration steps of the smart pressure transmitter are as follows:
(1) Adjust the measuring range to the required value before the migration;
(2) According to the measurement of the lower limit of the zero migration, input the lower limit corresponding pressure, with zero adjustment potentiometer adjustment, so that the output is 4mA;
(3) Review the full scale and fine tune if necessary;
(4) If there is a large amount of migration, the transmitter's transfer switch (connector) must first be switched to the positive or negative transfer position (determined by the migration direction), then the lower limit of the measurement pressure is added, and the zero point is used to adjust the potentiometer. Adjust the output to 4MA;
(5) Repeat step 3.
