An example of a Lead (or TSP) Sampler Calibration Data Sheet has been attached with
data filled in from a typical calibration. This includes the transfer standard orifice
calibration relationship which was taken from the Orifice Calibration Worksheet that
accompanies the calibrator orifice. Since this calibration is for a TSP sampler, the slope
and intercept for this orifice uses standard flows rather than actual flows and is taken
from the Qstandard section of the Orifice Calibration Worksheet. The Qactual flows are
only used when calibrating a PM-10 sampler.
The five orifice manometer readings taken during the calibration have been recorded
in the column on the data worksheet titled Orifice "H2O. The five continuous flow
recorder readings taken during the calibration have been recorded under the column
titled I chart.
The orifice manometer readings need to be converted to the standard air flows they
represent using the following equation:
