Table 10.3 Error conguration
Display item Description Default
Conductivity too high
(or Concentration)
Conductivity or resistivity is lower than the minimum limit. Warn.
Conductivity too low
(or Concentration)
Conductivity or resistivity is higher than the maximum limit. 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.
Calibr. time exceeded Calibration time exceeds the calibration interval (see Section 10.1.5). Off
Conguration error:
1st comp. matrix
2nd comp. matrix
The temperature compensation matrix is not dened properly (see
Section 10.1.4).
Fault
Concentration table The concentration table is not dened properly (see Section 10.1.6). Fault
CAUTION
If canceling an error conguration could be risky, do not cancel it as a dangerous situation may
result.
NOTE
Use not Conductivity but (Conductivity x cell constant) to set the error limit for “Conductivity too
high” and “Conductivity too low.”
NOTE
The temperature compensation is not performed around zero. In this case, a warning may be
issued.
10.4 Logbook conguration
In “Logbook conguration,” the user congures 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 conguration,” the user can select “Off,” “1-1,” or “1-2” for each item of interest to
be logged. 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”. This logbook may be full earlier.
It is recommended that important information be saved into the logbook “1-2”.
For “Erase logbook”, a specied 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.
