Do the cables used fulfil the required specifications?
Use a genuine E+H cable for
electrode and sensor connection,
see chapter "Accessories".
Are the installed cables strain-relieved?

cables separately to avoid any
mutual influence. Cable channels
are best.
No loops and cross-overs in the cable run?
Are the power supply and signal cables correctly connected?
Are all the screw terminals properly tightened?
For connection with potential matching (PML):
Is the PML connected to the measuring medium or the buffer
solution?
!
Note!
During calibration, insert the PML
into the buffer solution.
Are all the cable entries installed, tightened and sealed?
Cable run with "water sag"?
"Water sag": cable circuit hanging
down so that water can drip off.
Are all the housing covers installed and tightened?
Check seals for damage.
