System Status:
A
happy face indicates the system is ready. A sad face indicates an error
condition exists. A calm face indicates the system is in standby mode. Tap the
face for information regarding the condition of the detector and recommendations
to correct errors.
Standby Mode:
The
night icon indicates that the detector is in standby mode. In standby the gas
flow is shut off and all of the heaters are turned off. Tap the icon to switch
between modes. Alternatively, instead of entering standby mode you can use
the gas icon to shut off the gas when not using the detector.
Gas On/Off:
Tap
this icon to turn the gas flow on or off as indicated.
Run Status:
The
chart mode light is green when a data acquisition run is in progress, red when
the run has ended or is stopped, yellow when the signal is being monitored.
Control buttons are grouped on a control panel to the left
of the screen. Buttons are dynamically defined according to the function the
detector is performing. They are discussed in details at the place where they
are used.
There
are four windows on the top of Chart screen to display real-time running
conditions of the detector, independent of the operations on the Chart Screen
and other panels.
ELS
Detection Signal (V): The number in the window indicates detector
signal voltage.
Spray Chamber Temperature (°C):
This window displays the actual spray chamber temperature.
Drift
Tube Temperature (°C): This window displays the actual spray chamber
temperature.
Gas
Pressure (psi): This window displays the actual gas pressure.
There are four tabs on the center panel of
Chart screen, Chart, Setup,
Help, and Memo.
This tab plots the actual detector signal in
real time when charting is in monitoring mode.
The yellow light on the chart
mode light signal indicates monitor mode.
Tapping
the “Zoom Out” and “Zoom In” or “Auto Scale” buttons changes the voltage scale
displayed on the chart. The time scale of the chart is set on
Setup tab.
Tap the white area of the chart to redraw a one-minute
section of the signal auto scaled for closer examination of the chart. Tap again
to return to the normal chart scale.
