Read a pressure on A system using A 4-20mA pressure switch

HI All,

I am trying to read a pressure on A system using A 4-20mA pressure switch (0-40Bar 2 wire

It appears to be working but the readings look higher than I was expecting.

I am using A S7-1200 1212c connected to a WAGO 750-375 with an 750-455 Analog Input Module 4-20 mA

With the pressure set at 6 Bar (set against 2 standard pressure gauges, it reads 6.9 Bar on my PLC

See Attached pictures

Have I set this up wrong?

Thanks,

Ian
