MAINTENANCE AND CALIBRATION.
Enter security code
ROUTINE MAINTENANCE.
5 Weekly pipe rinse = NO
5 Weekly solution replacement = NO
Default calibration parameters = NO
Alter maintenance security code = xxxx
ROUTINE MAINTENANCE.
Energise AUTO ZERO valve = NO
Energise SECONDARY CAL valve = NO
Energise EMERGENCY SAMPLE valve = NO
Switch lamp on and measure = NO
Note. If any of the parameters on Page 2.2 are set
to YES, except for the EMERGENCY valve, it will not be
possible to proceed to Page 2.3.
SET UP CALIBRATION.
Initiate Manual AUTO ZERO = NO
SEC CAL solution value = xx<units>
Calibration Date (DD/MM/YY) = xx/xx/xx
Calibration time (HH:MM) = xx:xx
AUTO ZERO frequency = xx
AUTO ZEROs between SEC.CALS = x
Note. Programming Pages 2.4 and 2.5 are part of
the automatic calibration sequence. These displays cannot
be changed from these pages unless the sequence is
aborted.
AUTO ZERO SEQUENCE
Time to compensation = xx min
Abort AZ calibrations = NO
SECONDARY CAL = NO

xxxx
PAGE 2.1
Annual service = NO
PAGE 2.2
PAGE 2.3
PAGE 2.4
Reading = xxx<units>
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. Used in single stream mode only -
see Section 4.3.
Enter a security code (up to four digits) if required.
All programming Page 2.2 parameters normally set to NO, set
to YES as required (setting is maintained).
Used to energize the appropriate solenoid valve for test
purposes and operating the monitor on synthetic solutions.
Used to carry out tests on the electronic and optical sections.
Set to ROUTINE or BASELINE depending on the type of Auto
Zeroing required. See Section 7.
Used to enter the value of the Secondary Calibration prior to
calibration.
Sets the date when the first timed automatic calibration is to
be carried out.
Sets the time when the first timed automatic calibration is to be
carried out.
Sets the frequency at which the AUTO ZERO calibration takes
place. Select: OFF, 12h, 1 day, 2 days,......7 days.
Sets the number of AUTO ZERO calibrations that take place
between AUTO SECONDARY calibrations. Select 0 to 10 in
one unit increments. When 0 is selected a two-point calibration
will be carried out whenever a timed calibration takes place.
When SEC CAL set to OFF only Auto Zeros will take place.
Reading during calibration prior to compensation.
Remaining time to the end of the Auto Zero sequence.
When set to YES the sequence is aborted. The original zero
offset value is maintained.
When set to YES a two-point calibration takes place. This
option is not available when a BASELINE AUTO ZERO is
selected.
