6. Enter the span gas concentration if the concentration displayed on the
2020ppbPRO is different than the concentration of the span gas cylinder.
Press the “New” key and follow the display prompts. For further information,
see page 45 for numeric value, duration, time, and date entry. If the span
concentration matches the span gas cylinder concentration, press the “Next”
key.
7. Connect the span gas to the 2020ppbPRO tube holder inlet. The
2020ppbPRO will take 60-90 seconds to set the span set point. When
finished with the calibration, the 2020ppbPRO
will display “Calibration
complete”.
8. When the calibration procedure is finished, the display will show the lamp
condition assessment (i.e., GOOD, REPLACE SOON, BAD).
9. Replace the filter tube used during calibration with a fresh tube and the
instrument will be ready for sampling use.
NOTE: While the Cal status is active, all alarms are deactivated.
