Table 13.4 Error conguration
Display item Description Default
DO too high Input is over 50 μA (galvanic) or 1200 nA
(polarographic).
Warn.
DO too low Input is below −0.05 μA (galvanic) or −1.2 nA
(polarographic).
Warn.
Temperature too high Measured process temperature is higher than the
maximum limit.
Warn.
Temperature too low Measured process temperature is lower than the
minimum limit.
Warn.
Sensor membrane Sensor membrane is damaged. Off
Calib. time exceeded Calibration time exceeds the calibration interval
(see Section 13.2.6).
Off
CAUTION
If canceling an error conguration could be risky, do not cancel it as a dangerous situation may
result.
13.5 Logbook conguration
In “Logbook conguration,” the user congures information to be saved to a logbook or initializes
the logbooks.
Logbooks are used to keep an electronic record of events such as error messages, calibrations,
and programmed data changes. By referring to this log, users can, for instance, easily determine
maintenance or replacement schedules.
In “Logbook conguration,” the user can select “Off,” “1-1,” or “1-2” for each item of interest to be
logged. (For sensor 2, select “Off,” “2-1,” or “2-2.”) This can be done for items displayed on the
Settings logbook 1/3 to 3/3 screens. Assigning 1-1 or 1-2 to each item allows information to be
organized and logged in a logbook.
NOTE
Some events such as power-on are saved into the logbook “1-1” or “2-1”. This logbook may be
full earlier. It is recommended that important information be saved into the logbook “1-2” or “2-2”.
For “Erase logbook”, a specied logbook “1-1” or “1-2” can be erased individually.
When the “Warn if logbook full” is set to “Yes”, a warning is given when the logbook come to near
full (maximum 13 pages).
NOTE
When the logbook gets full, the oldest information is erased automatically.
