The purpose of the calibration is to calibrate the liquid system to
dispense accurate volumes. Refer to Figure 3–27, Liquid system
diagram. The instrument controls the dispensed volume by adjusting
the dispense pump speed and valve open time.
Calibration is performed at 100 μl and 300 μl. The weighed liquid mass
of each plate is entered into the Weight fields in the table in grams. The
software calculates the internal values of the mean volume per well and
