9.1 Stop Monitor
Select to stop the analyzer. When selected, the measurement
cell is emptied and the analyzer waits in the reset position
(piston down) awaiting a new command. The temperature of the
measurement cell is maintained at the set level ensuring no
warm-up delay when the analyzer is restarted.
9.2 Start Monitor Measurement
Select to start the analyzer. If the analyzer was switched off at
the mains, or a fault had occurred, measurement does not start
until the measurement cell reaches the operating temperature
set during configuration –
see Section 6.2.1, page 32. The
message 'Temperature Stabilising' appears at the bottom of the
screen until the cell is up to temperature.
If the analyzer has not been used for an extended period of time,
allow it to operate for a few hours and then recalibrate.
The analyzer runs automatically until it is switched off.
9.3 Calibrate
A manual calibration can be performed at any time. It is not
necessary to stop the analyzer.
Highlight the
button and press
to initiate calibration.
When calibration is complete, the measurement cycle begins
automatically.
9.4 Prime Lines and Calibrate
When the reagents are changed, or the analyzer is either
operated for the first time or operated following an extended
period of shut down, prime the reagent and sample lines. The
'Prime' function draws in each reagent, sample and standard in
turn, filling the lines and then pumping to waste. An automatic
calibration is then started. After calibration the measurement
sequence begins automatically.
If the analyzer is switched off at the mains without stopping
operation via the menu, or if a power supply failure occurs, the
analyzer starts the Prime Lines and Calibrate routine
automatically when power is restored.
9.5 Flush Monitor
This facility mimics the prime routine but does not store or
display measurement values.
The routine can be used
without
a prior calibration and is useful
when the measurement parameter is changed, for example,
from iron to aluminium.
When flushing is selected, this operation is continuous until
stopped by the user or a different operation such as 'Calibration'
is selected.
Note.
The 'Operate' menu can be accessed only from the 'Indicator View’ screen.
