Figure 6-3. Block Diagram: Pumping in the FLOW RATE Mode
In the FLOW RATE Mode, you pump fluid at a certain flow rate, without setting
the amount of time you pump or the amount of fluid you dispense. The pump
motor measures the time of pumping and volume of fluid dispensed but ignores
the TIME and TOTAL VOLUME settings.

To pump fluid in the FLOW RATE Mode, do the following:
1. Set up the pump motor for pumping, according to Chapter 3.
2. Toggle the ON/OFF switch to turn on the unit’s power. The display is in the
STOPPED Display Mode. Refer to Figure 6-3.
3. Either set the TUBE ID for the tube you are using (following Section 5.3) or
calibrate the tube (following Section 5.5), before continuing.
4. Press the FLOW RATE key.
The display flashes the current FLOW RATE setting (xxx mL/min or xxx L/min).
