F- 12.0.0 CALIBRATE/TROUBLESHOOT DIALYSATE PRESSURE

This is NOT a routine calibration! Follow the instructions exactly to avoid error!
Open the shunt door!
a)
b) Enter Service Mode → Calibrate Sensors →
Dialysate Pressure. The screen says "1. Connect
a pressure gauge in line...".
c) Figure right, connect the Four-Way
Assembly (P/N 150034) to the dialyzer
connectors.
d) ENSURE a transducer protector IS NOT in the 'to syringe'
tubing segment!
e) Place the Four-Way at dialyzer level!
f) If using a NEO-2 attach to the +Port (top
(red) port). If using a 90XL attach to the
Pressure Module's Gauge Port.
g) DO NOT allow tension in the Four-Way's tubing segments!
h) Clamp the 'to meter' tubing segment.
CLOSE the shunt door
i)
j) Press 'CONFIRM'. The screen says "3. Press [Dialysate Flow on/off] key..."
k) Press the Dialysate Flow on/off key. The Dialysate Flow lamp blinks.
l) ENSURE the external flow indicator is NOT moving!
Remove the clamp in the 'to meter' tubing segment!
m)
n) Using the syringe, adjust pressure until the external meter = between -2 and +2 mmHg.
o) Press 'CONFIRM' then see procedure number

F- 12.1.0 PRESSURE TEST

a) The screen says "6. Pressurize until dialysate pressure reads -250 mmHg..." .
b) PULL on the syringe plunger. Can you achieve negative (-)250 +/- 5 mmHg on the external meter?
Yes -250 achieved! Clamp the 'to syringe' tubing to hold this pressure then see procedure
number
No -250 CANNOT be achieved! ENSURE the transducer protector, at the meter, is NOT wet OR
consider replacing it! If OKAY, proceed to
and ENSURE the external flow indicator's 'bob' is moving up and down!
