Fig. 9.1 Operate Menu
9.1 Stop Monitor
Select to stop the analyzer. 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 34. 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 – see Section 4.1, page 22. 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 pumps sample through the flow cell continuously 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 ammonia to fluoride.
When flushing is selected, the operation continues until stopped by the user or a different operation such as 'Calibration' is selected.
