5.10 Calibrate Draft

(For PCA Models 15, 25, 35, 45, 55 & 65)

Material Required:

•Calibration Fixture (Section 5-2)

•Bellows (adjustable)

• Micromanometer

Range:

±20 mb (±8 in. H2O column)

 

Accuracy:

±0.025 mb (±0.01 in. H2O column)

Procedure:

 

 

IMPORTANT! In Step 1, do not connect the draft calibra- tion fixture to the analyzer until the Calibrate Draft Screen has been selected and displayed.

1.Enter the Calibrate Menu Screen per Section 5.3. Then choose to calibrate the draft sensor.

2.With the Calibrate Draft Screen displayed, connect the hose from the calibration fixture to the analyzer’s DRAFT port; then adjust the bellows for a micromanometer reading of –10 mb (–4" H2O column).

3.Wait until the MEASURED reading on the screen stabilizes. Then use the st and keys to enter an APPLIED reading* which equals the Micromanometer reading.

4.Press the key to calibrate the analyzer’s MEASURED value to that of the APPLIED value. At this time the Calibrate Menu Screen is redisplayed.

5.When all desired calibrations have been completed, press to exit to the Combustion Test Screen.

*The calibration range for this screen is –5 to –15 mb, any attempt to calibrate outside this range will cause the unit to display an error message.
