Explanation
3-P StdCAL
1000
10.0
0.02
Guided calibration with three perma-
nently set calibration standard solu-
tions.
The
3-P StdCAL
calibration is the rec-
ommended calibration type for most ap-
plications.
QuickCAL
10.0
Guided calibration with a single calibra-
tion standard.
With the
QuickCAL
calibration value,
the calibration graph of the
3-P StdCAL
calibration in the lower measuring range
is adjusted.
The calibration is only successful if the
measured value for the standard devi-
ates from the value of the
3-P StdCAL
calibration by less than ±50 %.
The measuring range for measure-
ments with the
QuickCAL
calibration is
limited to the lower range (see
section 7.2 T
).
