Why does the eja transmitter show a negative value? Neither the positive nor negative pressure sides are blocked

Why does the eJa transmitter show a negative value after it is installed?
First, calibrate the transmitter according to the operating conditions to ensure its accuracy, then check whether it is installed correctly and whether the pressure guiding tubes are unobstructed.......
The positive and negative sides of the reverse pressure tube are connected, and the gauge also works fine.
They’re all fine; it’s just that the high and low voltage measurements of the transmitter are reversed, or in reality the value is negative due to process conditions....
