5.3. Low Battery Alarm

When the batteries are nearly depleted, an empty battery icon appears in the

upper right corner of the display, and a short beep is sounded every 10

seconds.

After a low battery alarm occurs, the analyzer will continue to operate for only a

few minutes. The amount of operating time that remains depends on many

factors (e.g., pump and keypad backlight being ON or OFF, and the type and

condition of the batteries).

5.4. Locating Sampling Points

Forced Air Furnace Hot Water Tank

Figure 5-2. Forced Air Furnace

Figure 5-3. Hot Water Tank

For atmospheric burner or gravity vented,

forced air heating equipment with a

clamshell or sectional heat exchanger

design, test each of the exhaust ports at

the top of the heat exchanger. The probe

should be inserted back into each of the

exhaust ports to obtain a flue gas sample,

before any dilution air is mixed in.

Domestic hot water tanks with the ‘bell’

shaped draft diverter can be accurately

tested by inserting the probe tip directly

into the top of the fire tube below the

diverter.
