5.6. Selecting a Pressure Label

The pressure measurement can be labeled with types including, differential

across heat exchanger, draft reading, and differential pressure. See page 51 for

pressure and draft measurement procedures. Label data 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 highlight PRESSURE, and then press ENT to

display the PRESSURE MENU.

5.7. Temperature Label Selection and Measurement

The difference in temperature between two areas can be measured by using 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. Additionally, the temperature

measurement can be labeled. Label types include differential temperature

across heat exchange or differential temperature. 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 highlight TEMPERATURE, and then press ENT

to display the TEMPERATURE MEASUREMENT screen.

3. Install thermocouples in both temperature channel connectors.

4. Before taking a measurement, the temperature channels may need to

be zeroed, if not already displaying zero with both thermocouples

exposed to the same condition. Press ZERO (F2) if needed.

5. To label the data use the

◄►

buttons to scroll through the available

temperature label types. The current label will be used, saved, and

printed with the record.

6. Press ENT to save the selection and re-display the

TEMPERATURE MENU or ESC to exit back to the Main Menu.
