TMP- 1.4.2 CHECK PDIAL (DIALYSATE PRESSURE)
a) Clamp the four way's syringe tubing to hold pressure!
b) Call debug screen 0. If valve #25's dot IS blue (see Figure
right) then valve #25 is open. Continue to part c. If the dot is
NOT blue increase VEN (screen 1). If unable to make the dot
blue remove the tubing from the P
number TMP- 6.0.0
c) Monitor the PDial data window (see Figure right). Two scenarios:
1) PDial AGREES with the external meter within +/- 25 mmHg: See procedure number
TMP- 1.4.5 (page 184).
2) PDial does NOT agree with the external meter within +/- 25 mmHg: See procedure number
TMP- 6.0.0 (page 187).

a) Remove the clamps from valve #43!
b) Check the four way assembly connections for a leak. If SURE that the
assembly is NOT leaking see procedure number
