10.13. Adjustment of blood pump flow rate
10.13.1 In case of you use Standard Rolling Tube( 8× 12mm)
Adjust blood pump flow rate by setting blood line to blood pump to input GAIN and OFFSET values
of blood pump flow rate by referring to actually measured flow rate (discharged water weight or
volume/min) in maintenance mode 6 screen based on the following procedures.
(1) Required devices
Electronic balance or measuring cylinder
Stopwatch
(2) Turn on power SW of machine.
(3) Turn on [DIALYSIS] SW to shift to dialysis wait process.
(4) Release setting protection by selecting ON of “20.MAINTENANCE MODE FREE” in
maintenance mode 7 screen.
(5) Set blood line to blood pump.
(6) Place electronic balance or measuring cylinder below outflow end of the line to measure
discharged water weight or volume.

(7) Set blood pump flow rate to 50mL/min and operate the pump.
(8) Measure the discharged water weight or volume per one minute.
Flow rate (g/min or mL/min) = measured weight or volume ÷ time (one minute)
(9) Input “18.BPF(OFFSET)” value of blood pump flow rate in maintenance mode 6 screen value
to try to adjust the actual flow rate to about 50mL/min. Decrease (increase) the value if the
actual flow rate is higher (lower) than the set flow rate.
