When power is applied, the screen displays the Ecotech logo for a few seconds. It
then identifies the analyzer and the notation MAIN MENU appears in the lower right
corner. In the lower left hand corner there is the Ecotech Globe rotating,
indicating that the program is running. After the warmup period, the operation
mode is designated at the left of the screen and the current gas measurements for
the analyzer are indicated, as shown in Figure 2-7.
Instrument faults will be reported on the status line which appears one line below
the instrument state display. The following rules apply governing the information
displayed on this line: If there are no failures, the status line is blank. If there is a
single failure, that failure is displayed on the status line (i.e., ZERO FLOW, HEATER
FAULT, etc). The status line will clear when the fault clears. If there are multiple
failures, the failure at the top of the failure list will be displayed on the status line.
When this failure clears, the next failure on the list will be displayed. The entire
list of failures is displayed on the SYSTEM FAULTS screen.
Instrument gain (displayed above the operational mode) indicates the relationship
between the calibration concentration and a measured gas concentration within the
analyzer. It is an essential parameter for the calibration of the analyzer and is an
important requirement for system audits.
When the primary screen is displayed and the cursor is flashing in the words MAIN
MENU, press the <Select> or <Enter> key to enter the MAIN MENU.
