2.2.13. MAIN MENU FUNCTION Gas Data
This menu item is a read only display and when selected will show a sub menu as below:-
Preset
Received
Used
Hourly Average
Daily Average
The menu item Preset contains all gas data max, min, hi, lo and keypad entry values.
The menu item Received contains all gas data values that have been received either from a connected gas
chromatograph or from a supervisory system or as analogue inputs, together with the status of that
number for example N/A which means not available, a value has not been received.
The menu item Used contains the gas data values that are being used in the Model 2000 and the origin of
the number i.e. Keypad, OK or LGV.
The menu items Hourly and Daily averages display the current average values for all the gas components.
The Hourly average is calculated over the last complete hour and the daily average is calculated over
the last complete day from contract hour to contract hour. The Hourly and Daily Averages can be
selected to be calculated from either received Chromatograph values, received Serial (Modbus)
values or received analogue values.
All of the items of Gas data in this machine will be divided into pages with a maximum of four items per page, each item will
be displayed with the corresponding symbols, scaling factors and units.
2.2.14. MAIN MENU FUNCTION Liquid Data
This menu item is a read only display and when selected will show a sub menu as below:-
Preset
Received
Used
Hourly Average
Daily Average
The menu item Preset contains Specific Gravity (relative density) Liquid data, max, min, hi, lo and keypad
entry values together with the units of temperature measurement for liquid correction.
The menu item Received contains Specific Gravity (relative density) Liquid data values that have been
received either from a connected chromatograph or from a supervisory system or as analogue inputs,
together with the status of that number for example N/A which means not available, a value has not
been received.
The menu item Used contains the Specific Gravity (relative density) Liquid data values that are being used in
the Model 2000 and the origin of the number i.e. Keypad, OK or LGV.
The menu items Hourly and Daily averages display the current average values for Specific Gravity (relative
density). The Hourly average is calculated over the last complete hour and the daily average is
calculated over the last complete day from contract hour to contract hour. The Hourly and Daily
Averages can be selected to be calculated from either received Chromatograph values, received
Serial (Modbus) values or received analogue values.
