14’001 Titrator not ready Check if all cables are plugged to the titrator, restart
the system or call service.
14’002 Titrator information (version) Call service
14‘003 Titrator not started Titrator error. Check function in System Preparation/
Buret function. Call service.
14‘004 Titrator not started, pH value too low pH value is below the set endpoint. Verify the elec-
trode, dosing unit and boric acid.
14‘005 Titrator not started, pH value too high pH value is above the set endpoint. Verify the elec-
trode, dosing unit and receiving solution.
14’006 Wrong titration direction Ensure pH electrode is imersed in receiving solution
and verify if the right titration solution is used.
14’007 Titration speed over specification Overtitration. Use lower concentrated titration solution
or reduce titration speed.
14’008 Titration speed over specification Overtitration during back titration. Use lower concen-
trated titration solution or reduce titration speed.
