Co- 6.2.0 Calibrate/Troubleshoot Cond Cells - Fresenius Medical Care 2008K2 Troubleshooting Manual

CO- 6.2.0 CALIBRATE / TROUBLESHOOT COND CELLS
While in Dialysis, ENSURE the machine is clear of "No Water", Flow Errors and
Temperature alarms. Hydraulic alarm banners are not displayed in Service mode!
These are TROUBLESHOOTING procedure! Perform EXACTLY as written to avoid error!
IMPORTANT!
a) Install the hydraulics however, there is no need to screw in the rear panels yet!
IMPORTANT!
b) ENSURING plenty of known good acid and LIQUID Bicarb plug FIRMLY into each!
c) Place the machine into Service Mode → Calibrate Sensors →
Cond Cells
d) Install a Temperature / Conductivity meter into the dialysate
lines. Figure right, flow through the meter MUST directed
from bottom to top!
IMPORTANT! Close the shunt door!
e)
f) Follow the screen's instructions through: "4.
Waiting until the Conductivity value is
stable." The screen's [Conductivity] data
box is initially gray.
IMPORTANT!
g) ENSURING the external flow indicator's 'bob' is moving at least ¼ way up the sight
tube ALLOW six (6) minutes before continuing to STEP #1 below:
STEP #1:
Set the external meter to measure Temperature (°C). Watch it for thirty (30) seconds.
Between 35.1 and 39.9° C AND stable i.e. does NOT change more than +/- 0.25° C?
Yes Temperature between 35.1 and 39.9° C! Continue to STEP #2.
a) Return to DIALYSIS PROGRAM ("Select Program" → 'Dialysis' → 'CONFIRM')!
No
b) Proceed to
STEP #2:
Set the meter to measure Conductivity (mS). Its reading MUST BE between 13.0 and 14.5
mS?
Yes Between 13.0 and 14.5 mS! Continue to STEP #3 next page.
No NOT between 13.0 and 14.5 mS! See parts a AND b below.
SLAM
a)
"No Water" or Flow Error alarms the gauge cycles, approximately EVERY three
seconds, to about 25 psi. If not cycling return to Dialysis Program!
b) Proceed to
NOTE: If an "Operator Error" banner appears but the external flow indicator's 'bob'
continues to move up and down ignore the banner. If the 'bob' not moving it is
necessary to 'Escape' the calibration then reenter the Cond Cells calibration!
