TE-5170DV TSP VFC 18 Operations Manual
Step 4: Connect one side of a water manometer or other type of flow measurement device 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.
Step 5: Connect a water manometer to the quick disconnect located on the side of the aluminum outdoor
shelter (this quick disconnect is connected to the pressure tap on the side of the filter holder).
Step 6: Make sure the TE-5028A orifice is all the way open (turn the black knob counter clock-wise).
Record both manometer readings, the one from the orifice and the other from the side of the sampler. To
read a manometer one side goes up and the other side goes down, you add both sides, this is your inches
of water. Repeat this process for the other four points by adjusting the knob on the variable orifice (just a
slight turn) to four different positions and taking four different readings. You should have five sets of
numbers, ten numbers in all.
Step 7: Remove the variable orifice and the top loading adapter and install a clean filter. Set your timer.
Step 8: Record the ambient air temperature, the ambient barometric pressure, the sampler serial number, the
orifice serial number, the orifice Qactual slope and intercept with date last certified, todays date, site
location and the operators initials.
One example calibration sheet and one blank calibration sheet are attached to this manual. To download
the electronic spreadsheet, please visit www.tisch-env.com (download the TE-5170V High Vol TSP
