4.9 Draft Screens

The first Draft Screen is displayed by repeatedly pressing the MENU key from the Combustion Test Screen.

To measure draft, first zero the analyzer’s pressure sensor to atmo- spheric pressure by disconnecting the draft hose from the bottom of the instrument, and then pressing the

key. Reconnect the draft hose after the second Draft Screen appears (shown for 3 seconds). The third screen shows the current values of draft and stack temperature as measured by the analyzer.

When using the analyzer to make a differential pressure measurement (Section 4.4), the differential pressure value will be displayed on the third Draft Screen.

To save (S) or print (P) the screen data, first use the st keys to move the cursor (z) in front of the desired function, and then press the key.
