Calib pH? The tolerance of ± 100 mV during
pH-7 calibration was exceeded.
During slope alignment the range of
49...70 mV/pH value was exceeded-
was exceeded.
Check the electrode, cable and buf-
fer solution
Use fresh buffer solution
Check the values in the diagnosis
menu
Replace pH-electrode if necessary
If an impedance converter is used:
Replace battery
Calib ORP? The tolerance of ± 50 mV during
calibration with buffer solution 478
mV was exceeded.
Check the electrode, cable and buf-
fer solution
Use fresh buffer solution
Check the values in the diagnosis
menu
Replace Redox-electrode if
necessary
If an impedance converter is used:
Replace battery
Calib Cond.? The slope tolerance value was either
insufficient or exceeded.
Use fresh buffer solution
Calib Cl-N ? Slope error
The minimum slope value required
for slope alignment
(1.0 µA/mg/l Cl
