T- 1.0.20 Flow Through The External Indicator; T- 1.0.21 Isolate 'Actual' (Measured) Temperature - Fresenius Medical Care 2008K2 Troubleshooting Manual

T- 1.0.20 FLOW THROUGH THE EXTERNAL INDICATOR

a) Leaving Dialysate Flow on, install a Temperature meter (°C)
into the dialysate lines.
MUST be bottom to top!
CLOSE THE SHUNT DOOR!
b)
c) ENSURING the flow indicator's 'bob' is moving, see procedure
number T- 1.0.21 (page 232).

T- 1.0.21 ISOLATE 'ACTUAL' (MEASURED) TEMPERATURE

Is the meter's 'measured' temperature LESS THAN 35.1° C?
Yes Temperature is LESS THAN 35.1° C! See procedure number
No Temperature is MORE THAN 35.1° C! See parts a THROUGH e below:
a) Call debug screen 1.
Do NOT reset alarms!
b)
c) Press and hold the "1" key for five (5) seconds.
d) Allow FORTY-FIVE (45) seconds BEFORE continuing to part e.
e) Watch the meter for one (1) minute. TWO (2) possible scenarios:
1) IF between 35.1° C and 38.9° C AND STABLE i.e. does NOT change more than
0.2° C per minute:
2) IF UNSTABLE i.e. changes more than 0.2 °C per minute:
seconds THEN, ENSURING the 'bob' is moving up and down*, watch the meter for one (1)
more minute. Does it STOP changing more than +/- 0.2 °C (Yes or No)?
*
Note: If the 'bob' has stopped moving call debug screen 0. If Flow Error = 0 return to
Yes
Measured temperature STABLIZES. If (and ONLY if) between 35.1 and 38.9º C proceed
to
(ABOVE) procedure number
No
Measured temperature continues to be unstable. Watch the meter for five (5) more
minutes. THREE (3) possible scenarios 1) or 2) or 3) next page:
