SETTING THE VOLUME
This section applies to variable volume models only.
The volume of liquid to be aspirated is set using the
volumeter. The dials are colored either black or red to
indicate the position of the decimal point, depending
on the model (refer to Figure 4).

Lock System
For additional safety, the volume selected is lockable.
With the left or right thumb, unlock the thumbwheel
by pushing it up.
The volume is set by turning the thumbwheel.
The thumbwheel may be turned using only one hand
to slowly reach the required setting.
Push down the thumbwheel; the new volume
selected is locked.
To obtain maximum accuracy when setting the volume,
proceed as follows:
●
When
decreasing
the volume setting, slowly reach
the required setting, making sure not to overshoot
the mark.
●
When
increasing
the volume setting, pass the
required value by 1/3 of a turn and then slowly
decrease to reach the volume, making sure not to
overshoot the mark.

USER ADJUSTMENTS
Adjustment of the factory
calibration must only be
performed using a special
calibration key.
NOTICE
This section applies to Fixed models only.
PIPETMAN L Fixed is factory calibrated using distilled
water and very high precision balances. The nominal
value of the PIPETMAN L Fixed may be slightly adjusted
to compensate for liquids of different density or
viscosity.
To accomodate for density or viscosity, an adjustment
with one full turn of the calibration key in either
direction equals:
± 0.05 µL (models F1L to F2L)
± 0.2 µL (models F5L to F10L)
± 0.5 µL (models F20L to F25L)
± 2.0 µL (models F50L to F100L)
± 5.1 µL
(models F200L to F250L)
± 20 µL
(models F300L to F1000L)
102 µL
(model F5000L)
The cover is graduated in tenths of the key revolution
(letters A, B,... J) and is read from left to right. Each
small graduation mark represents 0.25 of the distance
between each letter.
Figure 6
To adjust your PIPETMAN L Fixed, hold the key in
the highest position to avoid banging it into the
hook.
