Campbell Scientific PWS100 Present Weather Sensor - Manual (Page 63)

Section 7. Operation
FIGURE 7-17. Calibration warning screen
Once confirm is typed followed by the return key, the CALIBRATION top
menu (see Figure 7-18) appears. The options available to the user are: 0 to
view and enter the calibration disc constants, and 1 to view and adjust the
PWS100 calibration.
FIGURE 7-18. Calibration top menu
Selecting option 0 on the CALIBRATION top menu will bring up the
CALIBRATION DISC CONSTANTS menu (see Figure 7-19). The following
can then be entered (each followed by the return key); the calibration disc serial
number, which identifies the specific disc for traceability; the size value; the
visibility value. The velocity value is fixed by the PWC100 calibrator unit and
is not a function of the disc and so this value is fixed and not user enterable.
