In this example the pump will ramp up from 10 ml mm to 20 ml mn over 60 seconds then continue to run at 20 ml min for another 10 seconds This is a Strategy 2 Program requiring four sequences 1 Specify the initial rate as a profile of 10 ml mn for one second 2 Specify the ramp up to 20 ml mn Since the minimum resolution of an increment is one second it will take 59 steps to reach the target rate Sequence 2 starts at time 1 second and ends at time 60 seconds giving it a duration of 59 seconds At one second a step 59 seconds divided by one second per step equals 59 steps The increase per step will by 20 ml mn minus 10 ml mn divided by 59 steps or 0 1695 rounded to four decimal places 3 Continue running at 20 ml mn for 10 seconds with a profile operation 4 Stop the pump Publication 5406 001 REV E i Harvard Apparatus PHD 4400 Hpsi Syringe Pump Series User s Manual Programming Tutorial Multiple Dispensing Example 75 a RATE ml min 25 SEQUENCE 1 2 EXTERNAL TIME gt Figure 8 Multiple Dispensing PROGRAM PRINTOUT PROG1 SEQ 1 DISPENSE 35 000 ml mn 15 000 ml 3 REPEAT INFUSE PROG1 SEQ 2 DISPENSE 65 000 ml mn 25 000 ml 2 REPEAT INFUSE PROG1 SEQ 3 DISPENSE 45 000 ml mn 17 000 ml 2 REPEAT INFUSE PROG1 SEQ 4 STOP Here a series of dispenses are programmed Each dispense is started by a trigger such as pressing the RUN STO
