The SETUP MENU allows the operator to change system parameters.

MAR 1 ‘12 12:45:00

Fuel: Natural Gas

Temperature Units: F
Measure Units: PPM
OxygenReference:TRUE

Pumps:SAMPLEDuty:90%
Dilute CO: 10000 PPM

Every parameter listed on the SETUP MENU screen can be changed as follows.

1. Use the

UP / DOWN

keys to move the cursor to the parameter you wish to

change.

2. Press

ENTER

to select the parameter. The value will be highlighted. This

indicates that you are in edit mode.

3. Use the

UP / DOWN

keys until the desired value of the selected parameter

appears on the display.

4. Press the

ENTER

key to confirm the selection. If you want to

cancel

any

changes made, simply press any MENU key.

A more detailed explanation of each parameter follows.

1) DATE & TIME: The analyzer’s internal clock is displayed in the format

month-day-year, hour-minute-second. Hours are always displayed using a 24-
hour clock.

2) FUEL: The fuel selection affects the following parameters: combustion

efficiency, carbon dioxide calculation, and display of toxic gases in units other
than PPM. The analyzer has the following fifteen fuels stored in its memory:
