Lower sensor trim excess correction on absolute pressure transmitter

Hello everyone, I’m from Taiwan and this is my first time, hope can help me solve this problem, Thank you so much!

Absolute pressure transmitter: 3051T Capillary type

Upper / Lower Limit: 0 ~ 1551.4 torr

The atmospheric pressure for the standard gage is 753 torr.

Installation site make a transmitter to get 826 torr, when I calibrate perform "Lower Sensor Trim"(TREX), I want to make the 826 torr become 753 torr, but the TREX showed "Excess Correction".

I know maybe move the transmitter close to installation site of the diaphragm will solve this problem, but how much distance to move? I don’t understand how to calculate.

Hope can help me solve this problem.

Many thanks!
