Good day,

I have differential pressure transmitter SITRANS P 7mf4432 and when I powered it I found that there is "LS" indication in the screen so I wasn't able to change some parameters in it like for example the engineering unit in menu no. 14 or the measured value display in menu no.13 so I want to know how to unlock the transmitter so that I can access and make changes to its menus.

Please find the attachments.

Thanks
