TE-5000-BL TSP 17 Operations Manual
6. Record the manometer reading from the orifice and the continuous flow
recorder reading from the sampler (if pen on recorder is off of chart, turn knob
on calibrator to get pen on chart for a readable number). A manometer must be
held vertically to insure accurate readings (one side of the manometer goes up
and one goes down, add both sides this is your H2O (in) ). Tapping the backside
of the continuous flow recorder will help to center the pen and give accurate
readings. Repeat this procedure by turning the orifice (TE-5028A) knob a little
bit (this will cause more resistance) and taking the manometer and continuous
flow recorder readings. Do this until you have 5 sets of readings. Sometimes it is
wise to take a few extra readings in case there is a problem with some of the
them. If you are using a fixed orifice (TE-5025A), five flow rates are achieved in
this step by changing the different plates to change the resistance.
7. Record the ambient air temperature, the ambient barometric pressure, the
sampler serial number, the orifice s/n, the orifice Qstandard slope and intercept
with date last certified, todays date, site location and the operators initials.
8. Disconnect the sampler motor from its power source and remove the orifice and
top loading adapter plate. Re-connect the sampler motor to the variac (TE-
5010).
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 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 H2O (in). 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:
Qstd = 1/m[(Sqrt((H2O)(Pa/760)(298/Ta)))-b]
