g) Is the external flow indicator's (#75) 'bob' rising, at least ½ way up, and falling?
Yes See procedure number
No a) If (and ONLY if) the screen says "Interrupted" repeat procedure number
T- 1.2.5
b) Proceed to page 49, procedure number
T- 1.2.6 CHECK TEMPERATURE
Allow five minutes, then CAREFULLY watch the external meter's reading for up to five minutes: Proceed
accordingly (three scenarios):
1) Temperature remains less than 35.5° C: See procedure number
2) Temperature exceeds (but does not remain at) 40.5° C: See procedure number
114).
3) Temperature remains greater than 35.5 but NEVER exceeds 40.5° C:
a) Calibrate COND CELLS per procedure. If (and ONLY if) the calibration is NOT successful
proceed to page 128,
b) Return to Dialysis program (remember to press the 'CONFIRM' key).
c) If the Temperature problem remains return to procedure number
T- 1.3.0 CHECK 'TEMP'
IMPORTANT!
a) Referring to the Figure (right), turn the
HEATER switch OFF (rocker switch pressed in towards "0" or
"OFF"). Leave it off until instructed otherwise!
b) Referring to the Figure (below, right), unplug the connector from
distribution board position labeled "MON-NTC" (
the left). This is temperature monitor sensor NTC #3.
c) Call debug screen 4. Is TEMP less than
Yes See procedure number
No No likely! ASSURE the connector at distribution board
position labeled "MON-NTC" (
was unplugged. If (and ONLY if) it IS unplugged see
procedure number
T- 1.3.1 CHECK TEMPERATURE DISPLAY FOR 80° C

34 C
a) Place the (6.808 K ) resistor plug, from the four-resistor
Temperature set into vacant distribution board position "MON-NTC"
nd

( position from the left).
b) From the Home screen, is Temperature between 33 and 35° C AND stable (i.e. does not vary more
0.2°
than +/- C)?
Yes See procedure number
No a) ASSURE the
position "MON-NTC". If not, repeat procedure number
b) See procedure number
