CO- 9.8.3 BALANCING CHAMBER VOLUME IS NOT FACTORY RECORDED

A clear, preferably glass, 100 ml graduated cylinder OR even MUCH
more preferable a calibrated scale is required! DO NOT use a larger
cylinder or gross error will occur!!
WITHOUT turning flow off
a)
from the 'To Drain' (*BOTTOM!) nozzle at the REAR OF THE
CAUTION!
MACHINE. *
drain' tubing causes gross error!
b) Allow ten (10) drain 'pulses' to ENSURE flow stability!
c) ACCURATELY, collect two (2) consecutive drain 'pulses'
into the cylinder. If a scale is used 1 ml = 1 gram. If a
scale is not used read the bottom of the cylinder's
meniscus curve (Figure right).
d) Reattach the drain tubing! TWO (2) possible scenarios:
1) IF (and ONLY if) measured volume is NOT
consistent between 58 and 62 ml: Proceed to

2) IF measured volume is consistent between 58 and 62 ml: See parts a AND b below:
a) Call debug screen 3. BCV (upper right, Balancing Chamber Volume) was
entered during the last BCV calibration (example: 603 = 60.3 ml)
b) Does BCV AND the measured volume match?
Yes
No BCV and the RECORDED volume do NOT match! Read parts a THROUGH c below
before performing them:
a) Perform the BALANCING CHAMBER VOLUME CALIBRATION,
b) Return to Dialysis Program ("Select Program" → 'Dialysis' → 'CONFIRM')!
c) Call debug screen 3. If the calibration took BCV = your RECORDED volume.
d) See procedure number
