The following data will now be entered into the two point scaling
"IN.SC.OF" method.
"INPUT1":
9949.5
"INPUT2"
36614.2
Ignore the decimal point position for the read values. Just note how
many zero's (or places to the right of the decimal) you need.
In this example there were 4 decimal places needed and there are 4
zeros after the "2" in the READ 2 value (ignore the decimal point).
You must alter the "RDG SC" factor as follows. Note that the
decimal point above in the "READ 1" and "READ 2" values is not
in the correct position. You need to move it 3 places to the left to
make it correct.
By looking at Table 8-3 below, you can see that a value of 0.00100
must be entered for a new "RDG SC" value.

Go back into the setup mode and enter the new "RDG SC" value,
the two point calibration data and move the decimal point.
You must proceed as follows.
