Programming and Operation

3. Observe display. 

 At each step of the program, observe the display. If 

necessary, re-enter the programming sequence.

Some helpful hints for reviewing your program:

• If the program is complex and contains several steps, write the steps on 

paper before entering the program. Check off each step as you review 
the program.

• If the program is intended for paced dispensing, review the program 

again, with the trigger depressed until the last step. Check the dispense 
pace to ensure the dispense steps are a comfortable speed.

C.2 Programming Examples

Examples of different pipetting sequences are described below, and are 
ideal for use as training exercises. Press the keys shown in brackets [ ], 
then press the [Vol] key until the volume in parentheses ( ) is displayed. At 
the end of the program, a triple beep tone    is sounded. (

see section D.3 

Recommendations for Accurate Pipetting for suggestions for better precision 
and accuracy

).

C.2.1 Sample Transfers

Example:

  Fill and dispense 100 µl.

Option 1

Option 2

[Fill]  

Vol

t

s

  (100) [Enter] 

or

[Fill]  

Vol

t

s

  (100) [Enter] [Enter] 

[Disp]  

Vol

t

s

  (100) [Enter] [Enter] 

The second option is a one-step program. Because the program ends 
at a volume greater than zero, and the last step is not a mix, a “Purge” 
prompt automatically appears at the end of the fill to dispense the liquid 
and return to the beginning of the program.
