12.2. Recalibration
The calibration of your
m
LINE pipette has been factory checked
by using forward pipetting technique and certi
fi
ed at 22°C using
grade 3 distilled water according to ISO 3696. The calibration is
based on ISO 8655-6: Gravimetric test method for volumetric
instruments. The pipette's speci
fi
cations are guaranteed only with
genuine Biohit tips. If you
fi
nd the pipette to be inaccurate after
performance testing, please follow the instructions below:
1. Remove the lid of the calibration nut, located at the backside
of the handle, with the aid of the calibration tool (Fig. 11).
2. Place the hexagonal head of the calibration tool into the hole
of the calibration nut.
3. Turn the adjustment lock counterclockwise to decrease and
clockwise to increase the volume.
4. Repeat testing the performance procedure (Chapter 12.1.).
Continue until the results are correct.
Note
: Recalibration is recommended if reverse pipetting technique
is used.
Note
: Biohit offers accredited calibration service. Please contact
