21) Press <F1:Edit> to enter the Edit Mode. Type the voltage read
from the multimeter (to a 3-digit accuracy; i.e., "0.xxx") in this
position and press <ENTER>. This calculates the "Span."
22) Ensure that the number now displayed in the row labelled "A/I"
and the column labelled "Calc" matches the number displayed on
the multimeter within ±0.005 volts.
23) Remove the multimeter leads from the interface board and the
Analog calibration cable from the back of the Partisol hub.
24) After the analog input calibration has been performed success-
fully, the temperature, pressure and flow calibrations must be
performed.
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.
25) Close the electronics compartment door and secure with the three
screws previously removed.
26) Go to Section 3.2.3.

Tools Needed: Temperature measurement device
Materials:
Follow these steps to calibrate the ambient air temperature:
1) If the Main screen is not currently displayed, press <Esc> until the
screen is shown (Figure 3-12).
2) The device must be in the Stop Operating Mode to perform an
analog input calibration. If the hardware is currently in the Run
Operating Mode, press <F4: Run/Stp> to enter the Stop Operating
Mode. The current operating mode is displayed in the upper
right-hand corner of the Main screen.
3) While in the Main screen, press <F5: Setup> and then <F2: Calib>
to access the Calibration screen (Figure 3-13).
4) Determine the current temperature (°C) at the ambient temperature
sensor mounted on the sample tube of the hub unit using an
external thermometer, [°C = 5/9 x (°F - 32)].
