12. Set the chart for 2.4 m distance adjustment at 2.4 m
from PAF.
13. Enter "240" on the left of "Calibration".
14. Click "Calibration".
15. Distance adjustment value (0.5 m and 2.4 m) will ap-
pear on the screen.
Adjustment value determination
Determining the adjustment value is done using "TEMP" and
the following 7 lines of values.
Temperature when TEMP = 2-point adjustment (ex. 25.0
→
250)
16-8 = AF adjustment values for each of the 7 blocks for
adjustment between 2 points
1. The temperature difference when adjusting between 2
points should be within ±1 degrees.
2. The adjustment is not OK if the adjustment value for any
one of the 7 blocks is substantially outside the range.
3. The adjustment is not OK if the difference between the
minimum and maximum values is ± 1.0 or more.
4. The adjustment is OK if the camera is moved and then
the difference between the minimum and maximum val-
ues is within ± 1.0.
