TE-5200 13 Operations Manual
sound is heard, a leak is present and the top loading adapter hold-down
nuts need to be re-tightened.
Avoid running the sampler for longer than 30 seconds at a time with
the orifice blocked. This will reduce the chance of the motor
overheating. Also, never try this leak test procedure with a manometer
connected to the side tap on the calibration orifice or the sampler. Liquid
from the manometer could be drawn into the system and cause motor
4. Connect one side of a water manometer to the pressure tap on the side of
the orifice with a rubber vacuum tube. Leave the opposite side of the
manometer open to the atmosphere.
5. Record the manometer reading from the orifice and the manometer reading
from the sampler. 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) ). Repeat this procedure by turning the orifice
(TE-5028A) knob a little bit (this will cause more resistance) and taking
both manometer 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 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
6. 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
7. Disconnect the sampler motor from its power source and remove the orifice
and top loading adapter plate.
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 Certificate that accompanies the calibration orifice. Since this
calibration is for a TSP sampler, the slope and intercept for this orifice uses
