Indicates the date when the next relevant routine maintenance
is required. When the date is exceeded, 'overdue' is displayed
and the 'Out of Service' l.e.d. is illuminated.
This message indicates that the monitor is working normally
but it is replaced with the relevant information, when
necessary, by the monitor diagnostics - see Section 8.4.1.
The control temperature of the two heaters is displayed in C.
Zero Offset indicates the zero drift since the last BASELINE
AUTO ZERO CALIBRATION.
The Calibration Factor is calculated after a SECONDARY
CALIBRATION; the nominal value is 1.00 but this differs
between individual monitors and the reaction control
temperature. It is intended to indicate the condition of the
monitor and the chemical solutions.
Current date and time.
The date when the next AUTO ZERO CALIBRATION is to be
carried out. If the automatic calibration is disabled, then OFF
is displayed in place of the date.
The date of the last ZERO calibration.
The date when the next SECONDARY CALIBRATION is to
be carried out. If the secondary calibration is disabled, then
OFF is displayed in place of the date.
The date of the last SECONDARY calibration.
Enter the value of the previously entered security code.
Set the following three parameters to YES when the tasks
are carried out. Once set to YES change the display on Page
0 to the required value.
Sets the date of the next 5-weekly service.
Sets the date of the next yearly service.
Used during routine maintenance to check the stability of the
monitor prior to calibration.
Enter a security code (up to four digits) if required.
