Debug Screen 5 Olc Values Table - Fresenius Medical Care 2008T Troubleshooting Manual

NOTE: Table B readings are affected by changing the [Dialysate Flow] rate, or turning it off, Filling
Programs, Pressure Tests and Temperature or Conductivity alarms (i.e. bypass). ENSURE the
machine is stable before responding to variations!

Description
2008T Troubleshooting Guide
P/N 490292 Rev. A
Should be within +/- 10 ml/min of the selected Dialysate
Flow rate
0 = Dialysate Flow is unstable
1 = Dialysate Flow is stable.
NOTE: QdS may = 0 if a Temp or Cond alarm occurs
OR if Dialysate Flow rate was changed OR if a Filling
Program occurs OR if a TMP alarm is reset
Ranges from 0 (unstable) to 100 (very stable)
Normally 0 or 1. If QbS reaches 20, the OLC test will
not start OR will cancel
When Dialysate Flow = 500 ml/min, should be more
than 70%. May be lower at other flow rates.
Defaults to 90. Decreases to 0 if Pre Dialyzer Cond is
stable
If OLC test is NOT running should be more than 90%.
Instability (i.e. less than 90%) is NORMAL within 12
minutes of an OLC test.
Defaults to 70. Decreases to 0 if Post Dialyzer Cond is
stable.
If OLC test is NOT running should be more than 90%.
Instability (less than 90%) is NORMAL within 12
minutes of an OLC test.
0 = An OLC test is NOT running
1 = At or going to approx.15.5 mS
2 = At or going to the approx. 13.5 mS
0 = OLC is turned off (OLC will NOT run).
1 = If OLC is turned on.
Not valid UNLESS an OLC test was performed.
Not valid UNLESS an OLC was performed.
