Making a Draft or Pressure MeasurementThe difference in pressure (ΔP) between two areas can be measured by usingthe analyzer's two pressure ports and the PRESSURE screen. By using the -ΔPport as the reference, the pressure applied to the +ΔP port will be displayed onthe PRESSURE screen as the differential pressure between the two ports.Perform a draft/pressure measurement as follows.Step Example Draft or Pressure Measurement Procedure1 Confirm that testing prerequisites have been completed (see page 61).2 Display the MAIN MENU by pressing the MENU (F2) button. If necessary,press ESC until MENU appears above F2.3 Use the UP () and DOWN () arrow buttons to select PRESSURE. PressENTER to display the Pressure screen.4 Before taking a measurement, the pressure sensor may need to be re-zeroed if it is not already displaying zero with both pressure ports open tothe atmosphere. If necessary, zero the pressure sensor as follows:• Press the ZERO (F2) button.• Disconnect any hoses connected to the +ΔP and -ΔP ports, and thenpress ENTER to zero the pressure sensor.• Reconnect any hoses. When measuring draft, leave the -ΔP portopen to the atmosphere and connect the probe's draft hose to the+ΔP port.5 Do one of the following to measure draft or differential pressure:• To measure draft, insert the probe into the stack and observe thedraft reading on the PRESSURE screen.• To measure differential pressure, connect sampling hoses to the +ΔPand -ΔP ports, and place the ends of the hoses into the two areasbeing compared. The differential pressure between the two areas isnow displayed on the PRESSURE screen. If the pressure at the +ΔPport is higher than the -ΔP port, the pressure reading will be positive.If it is lower, the reading will be negative.www.
