Initialization
3.4.1
Initialization Forces
IInitialization moves the plunger to the top of travel, then backs off a user-
specified number of increments (see k command) and sets this as position 0.
Also, the input and output positions of the valve are assigned depending on the
initialization command. All other command parameters are reset to default values.
The top of the syringe is recognized when upward movement of the plunger
causes an overload condition.
The force at which the plunger presses against the top of the syringe can be
controlled via a parameter after the Initialization command
(possible values are 0,
1 and 2).
Table 3-6 lists the recommended initialization force for each type of syringe.
Caution! To retain the integrity of the seal on smaller syringes, use a lower
initialization force than that for larger syringes. The default initialization speed is
500 Hz.
