Co- 3.0.0 Conductivity Is Good/Verify Display; Co- 3.1.0.2 [Conductivity] Window = 17.0 Ms; Co- 3.1.0.4 [Conductivity] Window = 10.0 Ms - Fresenius Medical Care 2008K2 Troubleshooting Manual

CO- 3.0.0 CONDUCTIVITY IS GOOD / VERIFY DISPLAY
a) If removed from a previous procedure, return
Conductivity Cell #7's connector to distribution board
position "X7, COND" (Figure right).
b) Call the Home screen.
c) Based on the machine's [Conductivity] window
now, THREE (3) possible scenarios 1) or 2) or 3)
below:
1) IF (and ONLY if) = 17.0 mS: See procedure number
2) IF (and ONLY if) = 10.0 mS: See procedure number
3) ALL OTHER scenarios: Is the machine's [Conductivity] window within +/- 0.4 mS of TCD?
Yes [Conductivity] is within 0.4 of TCD! See procedure number
No [Conductivity] is NOT within 0.4 of TCD! See procedure number

CO- 3.1.0.2 [CONDUCTIVITY] WINDOW = 17.0 mS

a) Return the concentrate connectors to their rinse ports!
IMPORTANT!
b) Place the machine into RINSE!
c) ENSURING a Flow Error NEVER occurs allow ten (10) FULL minutes BEFORE continuing to part d!
d) Call debug screen 5. If debug does not appear press 'Escape'
then call debug screen 5.
e) Is FPRE within +/- 400 of Pre Offset?
Yes FPRE within +/- 400 of Pre Offset! See procedure number
No FPRE is NOT within +/- 400 of Pre Offset! Pre Dialyzer Conductivity Cell #7 is bad (see
Figure 57, page 344).
CO- 3.2.0.4 [CONDUCTIVITY] WINDOW = 10.0 mS
Call debug screen 5. Is FPRE within +/- 10 of Pre Offset?
Yes FPRE within +/- 10 of Pre Offset +/- 10! Either Conductivity Cell #7 was not plugged into
distribution board position "X7-COND" properly OR is bad (to LOCATE Cell #7 refer to
57 (page 344).
No FPRE is NOT within +/- 10 of Pre Offset! Proceed to
2008K/K2 Troubleshooting Guide
