Gilibrator 3, How To - 5. Calibrating a GilAir Plus pump

Gilian Gilibrator 3 calibrator with StablFlow: True Primary Standard (NIOSH) Dry Cell Calibrator.

5. CALIBRATING A GILAIR PLUS PUMP

Excerpts:
"We are now going to demonstrate a GilAir Plus Pump being
calibrated.
We begin by setting up our sample train, where we will be using
a standard 3 pc filter cassette typically used for collecting
particulates. You will note that I have the filter with adapters on
each side connected between the pump and the calibrator.
I will next turn on my GilAir Plus Pump and hit the enter button
in the top right corner. The main menu will appear on the
pump’s screen. I will arrow down one time to the Flow Set
Option and hit enter. I can then use the plus and minus buttons
to adjust the flow rate to my desired setting.
For this demonstration I will set it at 2000 cc/min, aka 2 LPM. I
must then press enter again to save this desired set flow. I will
then arrow down once more, to the calibrate option and press the enter button once again. The pump will now begin to run in
the calibrate mode.
You will now notice that live readings will appear on the
Gilibrator 3’s home screen. You will also notice that the
back light in the Flow cell window is now on, and you can
see the puck oscillating in the calibration cylinder.
For this calibration, I would like to take a sample set of
10 samples. I can configure this by entering into the
settings screen and selecting 10 from the menu options.
Note that if I wanted a number not shown, I can press the
button with the three periods … and a keyboard will
appear that will allow me to enter a value.
I also want to make sure that my readings are precise, so I
will set my statistical threshold to 2.5%. That will alert me
if my percent deviation is outside of my 2.5% threshold.
Additionally, I want to configure some of the units of
measurement, so I will open my Display screen, and
change from degrees C to Fahrenheit, and hectopascals to inches of water for pressure. I then touch the home
screen button to return to the home screen, and I can see
that the units of measurements were updated to the
ones I just selected.
I also see down in the right lower corner that I selected a
sample set of 10 to be averaged.

"We have now completed the calibration for this Pump,
and it is ready to begin sampling. We will repeat this
verification check during post calibration at the end of the
sampling event. We will give the sample the same name
as the pre-calibration file, and it will link the two together."
