Output’ TTL line (PHASE 02). After 5.0 mL has been dispensed at 800 mL/hr (PHASE 03), the ‘Program
Output’ TTL line is lowered (PHASE 04), sending a synchronization signal to another device.
The pump then continues to pump at 800 mL/hr (PHASE 06) until a synchronization signal is received at the
‘Event Trigger’ TTL input, causing the Program to jump to Phase 7 (PHASE 05).
The pump then withdraws 0.25 mL (PHASE 07), pauses for 1 second (PHASE 08), then repeats this process if
the Program Input TTL line is low (PHASE 09), otherwise it continues with the next Phase.
Next, the pump pauses for 10 seconds (PHASE 10). Then it pauses again for the lesser of another 10 seconds
(PHASE 12) or until an Event Trigger occurs (PHASE 11). The Program then restarts (PHASE 13).

Example 9: Automatic Refill
While a foot switch is held, dispense continuously, starting with a 1.5 mL bolus. When the foot switch is
released, the syringe will refill to the volume that was dispensed.
In the pump’s general setup, set the TTL Trigger to “Foot Switch Hold” mode. Command: TRG FH
