2.7. Differential Pressure Connector (∆P)

Draft is measured by connecting the probe’s draft hose to the +

∆

P fitting, while

leaving the -

∆

P fitting open to the atmosphere. See Figure 2-5.

In addition to measuring draft, the “+” and “-” ∆P fittings can also be used to

measure the differential pressure between two areas by first connecting a hose

(P/N 0024-1103) to the -∆P fitting, and then inserting the open end of this hose

into the area being used as the reference pressure. The analyzer’s probe is then

inserted into the area where differential pressure is to be measured.

2.8. Primary Air Thermocouple Connector (T-AIR)

If thermocouple P/N 0104-1797 (10 feet long) or Utility Wand P/N 0104-1799

(12-inch ridged probe with handle and 5 foot coiled cable) is to be used to

measure the burner’s primary air temperature, then connect either of these

thermocouples to the analyzer’s T-AIR connector. See Figure 3-2 on page 22.

2.9. Computer Interface (USB)

Data stored in the analyzer’s memory can be downloaded to a personal

computer by connecting USB data cable P/N 0104-4032 between the USB ports

of the computer and analyzer. The PCA

3’s USB port is on its right side. See

Figure 2-1 on page 15.

2.10. Wireless Printer Port (IrDA)

Data that has been stored in the analyzer’s memory can be printed on a

compatible IrDA (Infrared data associated) wireless printer by aligning their IrDA

communication ports. The IrDA port of the PCA

3 is located at the top of the

device. See Figure 2-1 on page 15.
