fewer silo lines.
check electrode
With polarized electrodes. There is a break or short circuit.
Possible causes and rectification of the fault:
- the electrode is not plugged in ⇒ plug it in
- the electrode is not immersed in the solution ⇒ immerse it
- the electrode is defective ⇒ use new electrode.

lists.
division by zero The result could not be calculated as a divisor in the formula
was equal to zero.
Exit: Enter appropriate value.
EP overflow In a DET or MET titration 9 EP's or more were found. The first 9
EP's will be listed.
Remedy: Recalculation of data with higher EP criterion.
manual stop The determination has been manually stopped.
