D.1.2 Pipettor Calibration
To calibrate the pipettor:
1. Calculate display volume of the pipettor: D
v
=
V
p x C

a
V
p
= Programmed Volume
V
a
= Corrected Actual Volume (corrected for temperature)
C
p
= Calibration Point (each pipettor handle has its own
calibration point, see the table below)
D
v
= Display Volume

2. Enter the CALC mode on the pipettor by pressing the Special
Function key (use a pipet tip to press the key) until the
“CALC” function flashes on the display, followed by the
calibration point.
3. Press the [Vol] key to enter the Display Volume (D
v
)
calculated above.
4. Press the [Enter] key to set the calibration point. The display
shows “CAL” then “SET” to confirm the new calibration point,
and returns to the current pipetting program.
