For Single-channel
Take 10 measurements using distilled water at the
specifi ed readjustment volume.
For Multichannel
Take 10 measurements from the fi rst channel (1) and
10 from the last channel (8 or 12). Calculate the mean
volume from the 20 measurements.
For example, for an Ultra 8x300 the recalibration
volume is 60 μL. You set the LCD to show 60 μL, but
you calculate a mean volume of 58 μL; a mean error
of -2 μL. Reset the pipette to show:
Recalibration Volume
minus
Mean Error,
in this example 60 - (-2) = 62 μL.
Open the battery compartment, and plug in the
user-calibration tool (as shown) to reset the displayed
volume to 60 μL.
The LCD will show RECAL in the volume setting window. This
indicates that the factory calibration has been modifi ed. To
remove the RECAL sign and obtain a “factory” calibration, send
the pipette back to your Gilson distributor.
Remove the user-calibration
tool, close the battery com-
partment, and calculate the
accuracy as described in

Accuracy and Precision of
Gilson Pipettes”, which is
