4.13 Pipette
Adjustment
Pipette adjustment checks the accuracy and precision values of pipettes by weight analysis. The balance has a
built-in density reference table for water at temperatures between 10°C and 30°C. If other liquids are used for
pipette calibration, enter the liquid’s density at current room temperature in g/cc. Since all calculations are made
within the balance, the atmospheric pressure is also required.
Pipette adjustment can be accomplished
manually
(with a key press after each step) or
automatically
(weights
are automatically recorded when stable). Calculations made within the balance provide results of inaccuracy and
imprecision. Up to 30 samples can be used.
