CO- 1.0.11 VERIFY CONDUCTIVITY PROBLEM
a) Call the Home screen.
b) Referring to Figure 56
Pay attention ONLY to the value in the digital Conductivity window!
'Normal' conductivity differs between baths (example: between 1K and 3K), Sodium (Na+) and
Bicarbonate settings. Na+ and Bicarbonate levels should be set per a typical patient treatment!
c) Proceed accordingly (three scenarios):
1. = 17 mS: See procedure number
2. Less than 17 mS but higher than normal: See procedure number CO- 1.0.13 (page 134).
3. All others: Allow one minute then see procedure number CO- 2.0.0 (page 135).
CO- 1.0.12 CHECK PUMP CONFIGURATION
a) If bicarbonate is selected, ASSURE the red connector is attached to ACID and the blue connector is
attached to ADEQUATELY mixed bicarbonate. If not this may be the problem!
b) Referring to Figure 322
source to introduce a small air bolus then watch for bubbles through the Acid/Acetate inlet tubing. This
assures the acid pump is drawing.
c) Plug the bicarbonate (blue) concentrate connector into its rinse port. Does the acid pump stop
drawing?
IMPORTANT!
Yes
(page 134), the acid (Conc-P) and bicarbonate (Bic-P) pump distribution board connectors
are reversed.
No a) Return the bicarbonate connector to concentrate.
b) IMPORTANT! Allow three minutes.
c) See procedure number CO- 1.0.13 (page 134).
(page 133), IMPORTANT! IGNORE 'Status Bar' Conductivity related messages.
