CO- 2.0.9 ‘BOB MOVING’ / MEASURE TEMPERATURE
a) WITHOUT turning [Dialysate Flow] off, install a
Temperature / Conductivity meter into the dialysate lines.
IMPORTANT!
Figure right, flow through the meter MUST
be from bottom to top!
b)
IMPORTANT! Close the shunt door!
c) Set the meter to measure temperature (° C).
d) Call debug screen 1.
e) Press and hold the “1” key for five (5) seconds.
f) Allow two (2) full minutes BEFORE continuing to part g!
g) ENSURING the flow indicator’s ‘bob’ is moving up and down, is the external meter stable between
35.5 and 38.5° C?
Yes Between 35.5 and 38.5° C! See procedure number CO- 2.0.10 (page 342).
No NOT between 35.5 and 38.5! Proceed to
page 302
, procedure number T- 7.0.0 .
CO- 2.0.10 TEMPERATURE BETWEEN 35.5 AND 38.5 / MEASURE CONDUCTIVITY
a) Set the meter to measure Conductivity (mS).
b) Measured Conductivity is compared to TCD as seen in debug screen 1’s, C TCD
(lower left column). Example: 1360 = 13.60 mS.
c) ENSURING the flow indicator’s ‘bob’ is still moving up and down, based on the external meter’s
(measured) reading versus TCD , THREE (3) possible scenarios 1) or 2) or 3) below:
1) IF (and ONLY if) measured conductivity is within 0.4 of TCD AND stable i.e. does NOT
change more than +/- 0.15 per minute:
See procedure number CO- 3.0.0 (page 343).
2) IF (and ONLY if) measured conductivity
IS NOT
within 0.4 of TCD: Proceed to
page 366
,
procedure number CO- 8.0.0 .
3) IF measured conductivity IS MOSTLY within 0.4 of TCD BUT unstable i.e. changes more
than 0.15 per minute:
See parts a AND b below:
a) If removed from a previous procedure, return
Conductivity Cell #7’s connector to distribution
board position “X7, COND” (Figure right).
b) See procedure number CO- 5.0.0 (page 350).
