| C7-634 has high volatage (10 V) analog input only and isn't suited for direct connection of a load cell.

of course there is some module to amplify and linearize the mv of your Loadcell to 0-10V or maybe 4-20mA.just find the module and buy it.For Example for a pt100 I bought a transducer which did all the zero and spaning things.... Good luck
P.S: You should be abale to find schematics for this transducer all over the web. just take a look

Hi!
Right+Down+Esc= Hold and switchON = Delete Configuration & Set Password Default (100)
This will put C7 in transfer mode,but you must see if you want to delete configuration.
Best regards!

Added after 8 minutes:
Or you can try ESC+UP (during startup) for direct serial connection.
Best regards !
