End the linearity check by tapping on <Save>.
Screen display after a total of 9 syringe strokes:
better than ± 3.5 %
X
worse than ± 3.5 %
In order to perform a linearity check, tap on <Linearity Check>.
Proceed as described in the "Calibration Check" section.
During a linearity check, volume accuracy at different ows is tested. Three syringe strokes at a
low, three at a mid-range ow and three at a high ow are required.
With each syringe stroke, the volume accuracy should be within ± 3.5 %.
Linearity Check
It is important to pump without interruption from impact to impact. The rst pump stroke
is not relevant and will be discarded. Three pump strokes are required in each of the
following ow levels; low, mid and high range.
1 syringe stroke = pump twice, i.e. from impact to impact.
