12 Diagnostic Information
Ensure that a note is made of all the information in the
Diagnostic screens when contacting the Company regarding
spares or enquires.
12.1 Reagent and Solution Levels
Displays the predicted levels of the reagent solutions, along with
the approximate number of days remaining and the last date
that the reagents were replaced. Reagent consumption is
monitored by the analyzer and a diagnostic message appears
once a lower limit (customer configurable) is reached. Also
displays whether the clean and calibration solutions are LOW or
OK and the last date these solutions were replaced.
12.2 System Information
The system information screen provides details regarding the
calibration, maintenance and software release.
Last / Next Zero Calibration
– the date of the last
calibration and the scheduled date for the next – see
Section 7.4, page 45
Last / Next Secondary Calibration
– the date of the last
calibration and the scheduled date for the next – see
Section 7.4, page 45
Zero Offset
– a baseline calibration sets this offset to zero.
The result of a subsequent zero calibration is then
compared with the baseline to give the zero offset.
If the zero offset goes outside pre-configured limits the
calibration is not accepted and an alarm is triggered.
Calibration Factor
– the calculated value determined
during the last secondary calibration carried out. This
gives an indication of the sensitivity of the analyzer to
phosphate.
If the calibration factor goes outside pre-configured limits,
the calibration is not accepted, an alarm is triggered and
the actual calibration is shown here in red.
Next Service
– the due date for the next annual service –
Software Version
– the software release number.
LL App / OS / HMI App
– the low level application,
operating system and human-machine interface numbers.
IP address / MAC address
– communication settings.
12.3 Measurement Status
The temperature of the electronics and the chemical reaction are
displayed along with the millivolt output of the optical unit
(measure and reference circuits).
