Meter Setup

If y

ou selected Custom Range, the QC Range

screen opens and offers you the following

options:

■ Display target value (On/Off)

■ Deviation from target value (percentage

value). See page 69.

For the control solutions, the target value

always comes from the information stored

in the code chip. If you have chosen

Custom Range, you can now select an

allowed deviation from target value in the

range of 0 to 22.5% (in the illustration,

11.5%).

Note: Percentage deviation from target

value is always defined using INR values.

Even if you have activated % Quick in

the setup, the meter always calculates

the deviation using INR values; this

range is then converted to % Quick in a

second step. As there is no linear correla-

tion between values expressed as INR and

values expressed as % Quick, if you calcu-

late the percentage deviation (11.5 % in

the example) using the % Quick target

value, your result may deviate from the

result calculated by the meter using the

INR target value.

5 Touch On (the target value will be dis-

played with a test result) or Off (the target

value will not be displayed). Your selec-

tion is now highlighted.
