Instruction 24-9448 3-2
Initial Setup
3.2.2 Using the AC Power Adapter
The AC power adapter s capable of powerng the analyzer on a contnuous
bass. The adapter plugs nto an approprate 100–240 VAC, 50/60 Hz wall
outlet, and produces an output of +9 VDC. The adapter’s output connector
plugs nto the analyzer’s POWER jack located on the bottom of the unt
(Fgure 3-2).
If NMH rechargeable batteres are used, the adapter can also rapd
charge these batteres n approxmately 2 - 3 hours whle stll nsde the
analyzer. For the batteres to be charged, however, the analyzer’s battery
charger crcut must be turned ON per Secton 3.14.
3.3 Connecting the Probe and Hose Assembly
Do the followng to attach the probe and hose assembly to the analyzer
(Fgure 3-2):
1. Push the gas-sample hose connector, the larger of the two connectors (gv-
ng a slght twst), onto the analyzer’s GAS fttng.
2. Push the draft-hose connector, the smaller connector (gvng a slght
twist), onto the analyzer’s +∆P fttng.
3. Push the stack-gas thermocouple connector nto the T-STACK jack (con-
nector fts n only one way).
NOTE: The analyzer has a built-in temperature sensor for
measuring ambient temperature. Perform Step 4 only if the
optional primary / ambient air thermocouple is used.
4. Push the optonal prmary / ambent ar thermocouple nto the T-AIR
jack (connector fts n only one way).
IMPORTANT: To assure the accurate calculation of combustion
efficiency, the optional primary / ambient air thermocouple
must be used when the burner’s primary-air temperature is not
the same as the room temperature.
5. Inspect all hoses for cracks. If any hose s found to be defectve, re-
place the entre probe and hose assembly. Check that the water trap s
empty, and that the flter s not drty or saturated wth water.
