SECTION 5 - CONDUCTIVITY / ON LINE CLEARANCE PROBLEMS

External leaks, "No Water" and Flow Errors cause Conductivity problems. If either occur at ANY TIME
address them first! To avoid error observe ALL stated times below!
A) From the Home screen, ENSURE [Dialysate Flow] is on* and has been set to 800 ml/min for five (5)
minutes!
* If [Dialysate Flow] is blinking flow is off! Flow MUST be on!
B) If [Conductivity] is less than 12.6 mS, Figure right, ENSURE BOTH
connector plug O-rings are present! If not this may be the problem!
C) If the Automated Tests are running (screen reads "Test:....") allow them to finish.
Remove the 'dummy chamber' from the Level Detector.
D)
E) Press the [Temperature] window. Is "Temp Setting"
ALREADY = 37.0° C?
Yes "Temp Setting" already = 37.0° C! See part F.
No Adjust "Temp Setting" to 37.0° C THEN continue to part F.
F) Press 'Enter' to return to [Temperature].
DO NOT RESET ALARMS!
G)
H) Call debug screen 0. If Flow Error EVER = 1, even just
once, there is a Flow Error! WITHOUT LOOKING AWAY
watch it for, TWO (2) possible scenarios:
Scenario #1: FOUR (4) minutes, if it was necessary to adjust "Temp Setting" to 37.0° C in part E.
Scenario #2: TWO (2) minutes, if it WAS NOT necessary to adjust "Temp Setting" to 37° C in part E.
I) Is Flow Error is ALWAYS = 0?
Yes Flow Error ALWAYS = 0! See part J.
No Flow Error = 1 even if just once! Proceed to
DIALYSIS PROGRAM
J) Using a flashlight, ENSURE large air bubbles are NOT moving into the machine
through the acid and bicarb inlet tubing! If air is seen check the connector(s).
K) Call the Home screen. WITHOUT LOOKING AWAY, watch [Temperature]
AND [Conductivity] for one (1) minute. Based first on
TWO (2) possible scenarios next page:
