4.7 Temperature Measurement

The difference in temperature between two areas can be measured by us-

ing the analyzer's two temperature channels and the Temperature Screen.

By using the T-Air channel as a reference, the temperature applied to

the T-Stack channel will be displayed on the Temperature Measurement

screen as differential temperature between the two channels.

Perform a differential temperature measurement as follows:

1. Display the MAIN MENU by pressing the MENU (F2) button. If

necessary, press ESC until MENU appears above F2.

2.Usethe▲▼buttonstoselectTEMPERA-

TURE. Press ENTER to display the Tem-

perature Measurement screen.

3. Install thermocouples in both temperature

channel connectors.

4. Before taking a measurement, the tempera-

ture channels may need to be zeroed, if not

already displaying zero with both ther-

mocouples exposed to the same condition.

Press ZERO (F2) if necessary.

4.8 Saving Test Data

Up to 100 sets ("snap shots") of combustion test, pressure, or temperature

data can be saved in memory, which can later be recalled for viewing from

the Memory Directory.

1. First display the screen that contains the

data to be saved. In the example to the

right, all data associated with the Combus-

tion Test RUN screen will be saved.
