The total is seven sets of data. The next step is to put seven sets of data entered into the Instrument.
Pay attention to the input order in accordance with from small to large.
To enter the menu M48, then input the data set number "7", to be followed in the above seven sets of
data, we revised the setup of a multi-segment linearity correcting.
If you need to cancel linearity correcting, simply enter "0" in the menu M48.
Decommissioned linearity correcting, you just need to enter in the menu M48 data points (in this case,
is "7").
Noted: before the calibration of the instrument, you must first close the linearity correcting function. If
under the condition that the linearity correcting function has not closed, the calibration data sets arising
from the amendment must be dealing with the reverse curve of the data following the original
amendment, then input to the Instrument. Reverse amendment is very complicated, and should be
avoided.
