enter the value in the FTS Pres field using the keypad, and then
press <Enter>. The sampler will calculate the volumetric flow in l/
min.
14) If you are using the Streamline FTS Flow Transfer Standard, the
sampler will automatically enter the calculated flow into the "ACT
FLOW" field and compute "Span," which is the span slope for the
mass flow sensor. Record this number for future reference.
15) If you are using a different flow measurement device, you must
manually enter the volumetric flow in the "ACT FLOW" field by
pressing <F1:Edit> to enter the Edit Mode, moving the cursor to
the "ACT FLOW" field and entering the flow determined by the
external flow meter, followed by <Enter>. This causes the micro-
processor to compute "Span," which is the span slope for the
mass flow sensor. Record this number for future reference.
NOTE: If the instrument has been reset and you have recorded the value of
"Offset" and "Span" for the flow, you may enter these numbers directly when in
the Edit Mode.
15) Return to the Main screen by pressing <ESC> three times.
16) Restore the sampling hardware to its original state by removing
the flow metering hardware and re-installing the size-selective
inlet on the sample tube of the hub. Remove the filter cassette
from the hub unit, and discard the filter installed in it.
