F- 9.0.5 GOOD FLOW PUMP PRESSURE / ISOLATE CFS CIRCUIT
a) Return to Dialysis Program ("Select Program" → 'Dialysis' → 'CONFIRM')!
b) From the Home screen, set [Dialysate Flow] to 500 ml/min and press 'CONFIRM'.
c) Figure below, insert one of the resistor plugs, from the FOUR-RESISTOR SET, into CFS #10's
distribution board position, "x10, CFS".
d) Call debug screen 10. ACFS should = 0.0?
Yes ACFS = 0.0! See procedure number F- 9.0.6 (page 102).
No ACFS DOES NOT = 0.0! See parts a AND b below:
a) ENSURE the resistor plug was placed correctly at position "CFS" before continuing! If

A) With the machine off, swap in a known good Sensor Board
into T and C Mode (refer to OPERATING MODES (page Error! Bookmark not
defined.); C) IMPORTANT! Return to Dialysis Program. If ACFS = 0.0 the previous
