6. Press ENTER to save the displayed temperature value in the analyzer’s

temperature memory buffer and return to the Setup List screen.

Note: The temperature memory buffer is cleared when the analyzer is

turned off, or when the T-AIR thermocouple is installed after the entered

number is saved.

2.14.4 Internal Temperature Sensor Method

If a thermocouple is not plugged into the T-AIR connector, and there is no

data stored in the temperature memory buffer, then the analyzer defaults to

the instrument’s internal temperature as measured on the main printed

circuit board.

When viewing the T-AIR value on the Combustion Test HOLD/RUN screen,

the designation (I) will appear to the left of the temperature value. The letter

“I” signifies that the primary air temperature value was measured Internally.

For example:

T-AIR 86.5 °F (I)

1 2 ... 29 30 31 32 33 34 35 36 37 38 39 ... 85 86
