There are three circuit boards, a, b, and c, on which differential pressure transmitters A and B are installed respectively. When the balance valve is opened, two sets of data are obtained (in kPa): -1.887, -2.234, -2.04 and 0.037, -0.58, -0.243. Why is there a difference between these values? Is this normal?

The pressure transmitter can be connected to a testing bench, along with a standard gauge, to check whether the current output is normal; or a field tester can be used for comparison, which will help determine if there is an issue with the circuit board

Can it be determined empirically without a test bench or on-site tester?
