Model 633 Aethalometer® Black Carbon Monitor User Manual | Teledyne Advanced Pollution Instrumentation |
Manual flow calibration procedure:
13.The screen displays a message, “Wait for calibration to finish”, and then displays notice when the calibration is finished and prompts user to wait for next steps.
14.Remove the flow calibration pad, reinsert and tighten tape, and press OK, and wait for the chamber to return to home position.
After completion of manual (or automatic) flow calibration and the instrument is returned to operation mode, note that the intake flow reported from a flow meter does not match the reported flow on the front panel of the 633. This is normal due to leakage around the filter tape as discussed in Section 5.2. The difference in flow may be from 4 – 7% and the 633 compensates for this difference during the BC calculation.
There will be some faults present on the unit after the flow calibration is complete. To remove the faults, power down the instrument with both the front and back power switches, and then re‐start and allow it to cycle through the self‐test.
The manual flow calibration is now complete.
To resume taking measurements, go to the OPERATION>GENERAL tab and press Start.
