The cable lengths depend from many factors, first of all installation and cable protections (screen, earth, etc...). Assuming that instruments are installed in a workmanlike, for the maximum cable lengths should be followed the next suggestions:
DIGITAL INSTRUMENTS: see FAQ#073

It is not possible to repair/change the manometer without disassemble the load cell. The scope of the glycerine inside of the manometer display is only to show eventual tampering of the manometer. The load cell work properly without glycerine, too.
FAQ#015 - The anchor load value displayed on the load cell manometer or readout does not agree with load calculated by the hydraulic jack. What's right?
The main factors which influence the anchor measurements are:
– axial misalignment of the jack
– difference in diameter between the jack and the load cell.
These factors cause bending of the bearing plate between the load cell and the jack and affects the response of the cell. To minimise this effect use the genuine distribution plate which loads properly the sensitive upper ring of the load cell.
