Setting The Volume - PCE Instruments PIP 2 Manual Del Usuario

as prescribed by the Deutsches Institut für
Normung e.V. To verify the performance of
your pipette, request document DIN 12650.

2 SETTING THE VOLUME

The counter displays three figures to be read
from top to bottom. Additional to the figures on
the lower wheel are printed graduations of 2/10
which facilitate a volume setting in the range of
1/1000 of each pipette model.
Examples of the meaning of the black and red
figures :
Pipettes PIP 2,PIP 10,PIP 20:
red figures = 1/10
Pipettes PIP 100 and PIP 200:
black figures only = l
Pipettes PIP 1000 and PIP 5000:
red figures at the top = ml
The volume of the pipette is set by turning the
black knurled adjustment ring, Fig. 1B. To
obtain maximum accuracy and reproducability
always change the volume from the high to the
lower value :
 For
decreasing
adjustment ring slowly to the required
setting, making sure not to undergo the mark
 When increasing the volume turn the
adjustment ring until the lower figure wheel
comes 1/3 of a turn above the required
setting. Now turn the ring slowly backward
