AUTOTEST- 1.0.0 CHECK LOADING PRESSURE
The "IOS" test requires good loading pressure:
a) IMPORTANT! Assure the loading pressure gauge (with yellow connector) reads 0 psi before inserting!
b) SLAM the yellow connector into the red Acetate/Acid rinse port.
c) Repeat the "IOS" test. During the "Prep" phase, does loading pressure reach a maximum of between 17
and 29 psi?
Yes See procedure number
No a) Return to Dialysis program (remember to press the 'CONFIRM' key).
b) Proceed to page 18, procedure number
AUTOTEST- 1.0.1 TROUBLESHOOTING IOS FAILURE
The "IOS" test isolates the 'area' of Air Removal Chamber #69. If "IOS" fails all other leak tests are invalid!
a) Place the machine into Dialysis program (remember to press the 'CONFIRM' key).
b) Allow three minutes!
IMPORTANT!

e) If using a NEO-2 meter connect to the top pressure port (see Figure
right).
IMPORTANT!
f) Close the shunt door.
g) Pull on the syringe plunger. Are you able to create approximately -250
mmHg AND HOLD it (+/- 20 mmHg per minute) on the external meter?
Yes See procedure number
(page 231).
No Proceed to page 183, procedure

AUTOTEST- 1.0.2 CHECK DIALYSATE PRESSURE
a) Clamp the syringe tubing to hold pressure at the meter.
b) Call debug screen 0. Referring to the Figure (right), if (and ONLY if)
valve #25's adjacent dot is NOT blue see
232).
c) With approximately -250 mmHg on the external meter and referring to
the Figure (right), is the PDial window within +/- 25 of the external
meter reading?
Yes Return to
