Mean dev.
-999.9...999.9 e-20...e+20;
Mean deviation of calibration curve
Display of the calculated, mean deviation of the measured values
about the calibration curve in A, W or s. This value can be changed
manually.
The size of
Mean dev.
can be used as a measure of the quality of a
calibration curve.
This value can be used in formulae as

CSoln.name
8 characters;
Name of calibration solutions
The entry of a name for the calibration solutions is optional. The
names are used as follows:
•
Without 695 Autosampler, before every manual addition of a
calibration solution to the measuring vessel the message
Next
Standard, CSOLN 'CSOLN.name''Mass conc.' > M
appears with
details of the name and the mass concentration of the calibration
solution.
•
If work is performed with the 695 Autosampler with
Auto.samples
= on
, all calibration solutions must be entered on the "SAMPLES"
page. We advise you to enter the names
CSoln.name
there as
sample identification.
