T- 1.0.17 Simulate Conductivity; T- 1.0.18 Conductivity Is Between 12.9 And 14.5/Verify Conductivity - Fresenius Medical Care 2008K2 Troubleshooting Manual

T- 1.0.17 SIMULATE CONDUCTIVITY

a) Figure right, leaving the 6.04 KΩ resistor in, plug the
274 Ω
resistor plug, from the
SET
into the Cond Cell's distribution board position,
"X7, COND".
b) Watch the [Conductivity] window for one (1) minute.
THREE (3) possible scenarios 1) or 2) or 3) below:
IF (and ONLY if) BETWEEN 12.9 and
1)
14.5 mS AND does NOT change more
than 0.2:
IF (and ONLY if) BETWEEN 12.9 and 14.5 BUT changes MORE than 0.2:
2)
(3) possible bad components (see COMPONENT LIST below). Turn the machine off and swap in
each, one at a time, in between returning to Dialysis Program, until [Conductivity] is STABLE
between 12.9 and 14.5 mS.
COMPONENT LIST: 1) Sensor Board

To prevent "Cond Offset Failure" place the machine in T and C Mode (refer to
MODES, page Error! Bookmark not defined.))
IF less than 12.9 OR more than 14.5 mS:
3)
a) Remove the
TWO-RESISTOR SET.
b) If (and ONLY if) [Conductivity] is still is less than 12.9 OR more than 14.5proceed to

T- 1.0.18 CONDUCTIVITY IS BETWEEN 12.9 AND 14.5 / VERIFY CONDUCTIVITY
Based on the [Conductivity] window's color, TWO (2) possible scenarios:
1) IF (and ONLY if) pale / yellow white: See procedure number
2) IF RED: See parts a THROUGH d below:
a) At the bottom of the screen, select the 'Dialysate' tab.
b) Figure right, if necessary adjust the Limits until
the 'Actual' Conductivity is CENTERED between
them.
IMPORTANT!
c)
d) Allow two (2) minutes or until if the [Conductivity] window turns white. TWO (2) possible scenarios
