T- 7.6.0 METER TEMPERATURE IS STABLE AT 37°C / CHECK NTC #3 STABILITY
The screen’s [Monitor Reference] data box should be gray AND at this point it does not matter if it = 37° C!
WITHOUT LOOKING AWAY, watch it one (1) minute noting its highest and lowest value. TWO (2) possible
scenarios 1) or 2) below:
1) IF (and ONLY if) [Monitor Reference] changes more than +/- 0.2° C: ENSURING the external
meter is STABLE between 36.9 and 37.1° C, proceed to
page 314
, procedure number T- 7.8.0 .
2) IF [Monitor Reference] does NOT change more than +/- 0.2° C: See parts a AND b below:
a) ‘Sharply’ press ‘CONFIRM’ to turn the [Monitor Reference] data box pale yellow / white.
b) Activate [Monitor Reference] , it turns bright yellow. Without pressing CONFIRM until instructed can
you adjust [Monitor Reference] to match the external meter?
Yes [Monitor Reference] should be bright yellow AND between 36.9 and 37.1° C. See
procedure number T- 7.6.2 (page 311).
No Swap in the listed components (see COMPONENT LIST below), one at a time, with known
good, in between returning to (ABOVE) procedure number T- 7.2.1 (page 305) to test each
new component.
COMPONENT LIST: 1) NTC #3 (to LOCATE NTC #3 refer to Figure 42 , page 218);
2) Functional Board.
T- 7.6.2 TEMPERATURE CHECKS / SLOW FLOW CALIBRATION?
CAREFUL HERE! This procedure determines if a ‘Slow Flow’ Temperature calibration is necessary:
a) ‘Sharply’ press ‘CONFIRM’! [Monitor Reference] MUST return to pale yellow / white!
b) ‘Sharply’ press ‘CONFIRM’ again. TWO (2) possible scenarios:
1) IF the screen says “9. Connect an external temperature meter…”: A ‘Slow Flow’ calibration is
required! See procedure number T- 7.6.4 (page 312).
2) IF the screen says “Calibration saved. Press CONFIRM”: If the procedures were done correctly
the [Monitor Reference] data box is GRAY. Does it continue to read between 36.9 and 37.1° C?
Yes The GRAY data box = between 36.9 and 37.1° C. This completes the calibration
HOWEVER, if you started out troubleshooting a “TEMP OVER 95 DEGREES” alarm in
Heat Disinfect return to procedure number
T- 1.5.1 (page 247). If not, return to Dialysis
Program.
No The GRAY data box does NOT = between 36.9 and 37.1. Swap in the listed components
(see COMPONENT LIST below), one at a time, with known good then return to (ABOVE)
procedure number
T- 7.2.1 (page 305) to test each new component.
COMPONENT LIST: 1) NTC #3 (to LOCATE NTC #3 refer Figure 42 , page 218);
2) Functional Board.
