IMPORTANT!
d) Do NOT reset alarms!
IMPORTANT!
e) With the Bypass LED OFF, is the external flow indicator's (#75) 'bob'
rising (at least ¼ way up) and falling (see Figure right)?
Yes See procedure number
No a) If (and ONLY if) the Temperature window is RED repeat from procedure
number
b) If (and ONLY if) the Conductivity window is RED repeat from procedure
number
c) Proceed to page 14,
CO- 2.0.7 CHECK 'OUT OF BYPASS' FLOW STABILITY
Call debug screen 6 and CAREFULLY watch BC Switch for one minute. Is it REMAINING between
and 396 (3.24 and 3.96 seconds)?
Yes See procedure number
No a) Call the Home screen and make ASSURE Dialysate flow rate is still set 500 ml/min. It may
have defaulted to a different rate (idle flow option). If (and ONLY if) selected Dialysate flow
is NOT 500 changed return to procedure number
b) Proceed to page 14,
CO- 2.0.8 CHECK TEMPERATURE / CONDUCTIVITY
a) Without turning Dialysate flow off, place a calibrated conductivity meter into the dialysate lines.
IMPORTANT!
b) Close the shunt door!
c) Allow two minutes for the meter reading to stabilize.
d) Set the meter to read Temperature. ASSURING the Bypass LED is REMAINING off, if (and ONLY if) the
meter's Temperature reading is NOT remaining between 35.5 and 38.5° C proceed to page 94,
procedure number T-
e) Set the meter to read Conductivity. ASSURING the Bypass LED is REMAINING off the meter's
Conductivity reading is (four scenarios):
NOTE! If using a NEO-1, its display reads
1. Remaining lower than 'normal': See procedure number
2. Remaining higher than 'normal': See procedure number
3. 'Normal' and stable (does NOT vary greater than +/- 0.15 mS per minute): See procedure
number CO- 3.0.0
4. Unstable (varies greater than +/- 0.15 mS per minute): See procedure number
(page 142).
CO- 3.0.0 VERIFY POSSIBLE CONDUCTIVITY DISPLAY PROBLEM
a) If removed from a previous procedure, CAREFULLY return conductivity cell #7 to distribution board
position labeled "COND" (6
b) From the Home screen, proceed according to the machine's Conductivity display (three scenarios):
