Adjusting the mechanical zero point of the EJA transmitter shouldn’t affect the migration amount, right?

I don’t think the EJA double-flange differential pressure transmitter can be used for measuring liquid levels
Mechanical zeroing simply adjusts the value to 0 within a small range; what changes is only the PV value, and it has nothing to do with the range!
It depends on the circumstances in which you perform zero adjustment; when the actual liquid level is zero, it is correct to carry out a mechanical zero adjustment so that the transmitter’s output is also zero. It shouldn’t be done just anytime； Additionally, adjusting the zero point changes the migration amount, but the range remains unchanged.
Making small adjustments is no problem
Once the mechanical zero point is adjusted, the migration amount is also adjusted, but this does not affect the range.....
