User Concentration Methods
It is possible to enter and store up to 10 User Concentration Methods.
Therefor you need 2 to 14 standards of known concentration and one blank (deionised water
or reagent blank value). The Standards should be measured with increasing concentrations
and from the brightest to the darkest colouration.
The measuring range for „Underrange“ and „Overrange“ is defined with –2600 mAbs* and
+2600 mAbs*. After selection of a method the concentration of the lowest and highest used
standard is displayed as measuring range. The operation range should be within this range
to achieve best results.
*1000 mAbs = 1 Abs = 1 E (displayed)
