4. Perform a barometric pressure calibration. Start a barometric pressure calibration. Refer to Section
7.3 of the Operations Manual for performing a barometric pressure calibration. Enter the following
The current reading of barometric pressure of the TE-Wilbur
The current reading of the calibrator barometric pressure
The value of barometric pressure the TE-Wilbur system was left
at. This should always be the calibrator reading
5. The second box is the flow calibration. Start a flow calibration. Refer to section 7.5 of the
Operations Manual for performing a flow calibration.
At each setpoint screen (Setpoints will be 15.00/15.83/16.67/17.50 LPM when running at 16.67
LPM setpoint) record the following values in the Flow Calibration section of the worksheet. Repeat
this 4 times for each setpoint
This is the current reading of the TE-Wilbur flow
This is the current reading of the calibrator
The value of flow the TE-Wilbur system was left at. This should
always be the calibrator reading
After all 4 setpoints are entered and the calibration is successful, write down the Slope, Intercept
and R2 factor in the spaces provided. Perform a flow verification by running the sampler at 16.67
Lpm. Write down the setpoint and the as found value, these should be the same.
6. The last box is the leak check results. Start a leak check. Refer to Section 11.0 of the Operations
Manual for instructions on performing a leak check.
Record the start pressure after the system stabilizes, the fail pressure displayed on the screen and
the final ending pressure after the leak check completes. Check the pass or fail box depending if
the leak check has passed or failed.
7. Sign and date the calibration worksheet.
