draft, and differential pressure.

The analyzer can also directly measure and display NO, NO2 and SO2 with the installation of the appropriate sensors. Combustion efficiency calculations can be conducted for a variety of fuels (see Specifications later in this chapter).

B-Smart® sensor technology allows a new sensor to be installed in the field without having to calibrate the analyzer with gas before use.

Advanced data storage and communication features allow the operator to store up to 500 individual combustion test records, which can later be recalled for viewing, printing, or downloading to a personal computer. In its data logging mode, the analyzer can store an additional 500 data logged records. The optional AC power adapter allows the analyzer to run for extended periods of time while data logging.

The optional sample conditioning probe is recommended when measuring NO and SO

to ensure the highest degree of measurement accuracy.

A probe and hose assembly with an integral thermocouple and filter/water trap connects to the bottom of the analyzer, providing the means of drawing in gas samples and for measuring stack temperature and draft.

1.5. Operation Overview

1.5.1. Turning On the PCA®3

The PCA®3 is turned ON by pressing its red I/O button. A warm-up period of 60 seconds then begins, during which time the analyzer performs self diagnostics. At the end of the warm-up period, if no errors were detected the instrument will display the Combustion Test HOLD screen. If errors were detected, the message

Figure 1-2. A Typical PCA®3 Kit

0024-9472 Rev 3 9

www.GlobalTestSupply.com

PCA3 Manual

“ERRORS DETECTED” is displayed along with a list of the errors. These errors must be corrected before proceeding with the combustion test.

Before starting a test be sure to select the fuel being burned. The default fuel selected is Natural Gas. Note that the name of the fuel being burned is indicated at the top of the run/hold screen.

1.5.2. The Combustion Test

To assure correct combustion efficiency calculations, the analyzer must know the burner’s primary-air temperature. The analyzer normally uses its internal temperature sensor for the primary-air temperature value, but this method is only acceptable if the burner is using ambient room air. If the burner is drawing in cold outside air, we recommend that the optional T-AIR thermocouple be used. This thermocouple plugs into the bottom of the analyzer and is placed in the burner’s primary-air stream.

Begin the combustion test by first inserting the analyzer’s probe tube into the stack-gas stream of the appliance under test, and then pressing the RUN/HOLD button to display the Combustion Test RUN screen. The analyzer will begin to continuously monitor the stack temperature, %O stack gas and then display measured and calculated values on its display. The recommended time required to achieve a stable measurement is a minimum of 3 minutes.

During a test, the CO

sensor is protected from high CO levels by being

LOW

automatically flushed with fresh air when the detected CO level exceeds 4,000 ppm. The analyzer will automatically start using its optional CO if installed, at CO levels starting at 4,001 ppm, thus providing continuous CO readings up to 20,000 ppm.

A keypad backlight enables a user to read the keypad in dimly-lit areas. Turn the keypad backlight ON and OFF by briefly pressing the I/O button.

1.5.3. Turning Off the PCA

The analyzer is turned OFF by pressing and holding down the I/O button for at least 2 seconds. Note that there is a 5-second delay before the analyzer actually turns OFF, during which time the analyzer can be turned back ON by pressing the RUN/HOLD button. In addition, there is a gas-purge feature that keeps the analyzer’s pump running if the gas level inside the sensor chambers is abnormally high at shutdown. With the probe removed from the stack and sampling fresh air, the analyzer purges itself until the detected gas concentrations drop below predetermined levels.

Replace the filter if it looks dirty. See Replacing the Filter Element on page

83.

When sampling flue gas, keep the analyzer above the water trap, and keep
