the Direction, Volume, Rate, Load Rate, Load Threshold and Drawback settings. Pressing the STOP push-button can
stop the dispensing at any time.
When drawback is enabled, the Volume setting specifies the net fluid displaced, the actual forward motion is the sum
of the specified dispense volume and the drawback volume. The Drawback Rate during drawback and the Drawback
Dwell (time between the forward and reverse portions of the cycle) settings are shown on the Drawback screen.
3.2.9.3 Meter
Press the METER SCREEN push-button to enter Meter Mode. If the METER SCREEN is not shown go to SETUP A

ADVANCEDOPERATION
The Controller Module provides the controls for producing fluid flow via a positive displacement pumping mechanism.
The systems utilize solid-state electronics, stepping motor drives, and precision machined ceramic pump heads.
These components combine to provide exceptional accuracy and precision, high reliability, and low maintenance.
Volume commands for the Controller Module use microliters. Rate commands are in microliters per second. Pumping
is started using the Start push-button
based on the screen being viewed. Push the Stop push-button
to
stop the operation before the respective volume setting is reached.
3.3.1 Production Mode
Production Mode provides precision dispensing and metering operations. Three Dispense Modes (Dispense,
Dispense Minimum Chamber Volume, Dispense Multichamber) and two Meter Modes (Meter, Meter Multichamber)
