Selecting Pump and Gearbox Values
In the Gearbox pulldown menu, select CP-DSM1 for Model M6 or CP-DSM2
for Model M50.
In the Pump pulldown menu, select 100 for Model M6 or 625 for Model M50.
(The values 4 and 750 are currently unused.) These values represent
nominal µL/revolution for the two models. The next section discusses how
these can be overridden for greater accuracy.
Setting the Backlash and Volume/Revolution Values
Backlash is defined as the transition from the aspirate function to the
dispense function, or vice versa. The MicroLYNX software observes the
factory default settings of 1.5 µL for backlash, and 100 µL or 625 µL for
volume/revolution (as set above, depending on the pump model).
However, the actual values for each pump are calibrated and recorded on
the QC certificate supplied with every unit. There are several situations,
delineated below, in which these values must be entered manually to
override the factory defaults.
Manual entry of backlash and µL/rev values is required:
• For all uses of a Model M50 pump
• For all applications utilizing M6-LHS software
• For all applications utilizing IMS software (Refer to page 23.)
• When a pump is repair or replaced
SELECT 100 FOR MODEL M6
OR 625 FOR MODEL M50
SELECT CP-DSM1 FOR MODEL M6
OR CP-DSM2 FOR MODEL M50
