Gray (ghosted): Select the 'Both Tests' button then press the 'CONFIRM' key
Blue (active): Select the 'Pressure Test' button then press the 'CONFIRM' key.
d) Allow the Pressure Tests (Neg Flow On, Pos Flow Off) to complete: Two scenarios:
1) Pressure Tests FAIL: Proceed to page 194, procedure number
2) Pressure Tests PASS: Repeat the Pressure Tests. Do they pass again?
Yes See procedure number
No Proceed to page 194, procedure number
TMP- 6.0.0 CALIBRATE DIALYSATE PRESSURE
This is NOT a routine calibration. Follow the instructions exactly to
avoid error!
a) Referring to Figure 70
check the (blue) dialysate pressure transducer (#9) for signs of
external (rust colored) fluid leakage. Replace the transducer if
leakage is located as this may be the problem!
b) At the four way assembly (see Figure right) clamp the
tubing attached to the external meter and syringe.
c) If using a NEO-2 meter connect to the top pressure port
(see Figure above, right).
d) Place the machine into Service Mode
Calibrate Sensors
e) Assure the shunt door is closed and there
is 'air free' flow through the external flow
indicator (#75).
f) Press the 'CONFIRM' key. The screen changes.
IMPORTANT!
g) Turn Dialysate flow OFF (Dialysate Flow on/off LED blinks).
IMPORTANT!
h) Remove the clamps from the external meter and syringe tubing!
i) Using the syringe, adjust pressure until the external meter reads 0 +/- 2 mmHg. The screen's [Dial
Pressure Reference] data box reads approximately 100 if the procedure was performed correctly and
the dialysate pressure circuit is okay.
j) Press the "CONFIRM' key. Does the message "Operator Error" occur?
Yes See procedure number
No The screen changed. See procedure number
TMP- 6.1.0 CONTINUE DIALYSATE PRESSURE CALIBRATION
a) Pull on the syringe to create negative (-) 250 +/- 2 mmHg on the external meter.
(and ONLY if) -250 cannot be achieved OR pressure does not HOLD (+/- 20 mmHg per minute) see
procedure number TMP- 1.4.3
b) Clamp the syringe tubing to HOLD pressure.
HOLD) +/- 20 mmHg per minute) see procedure number
c) The screen's [Dial Pressure Reference] data box should read approximately 140.
d) Press the "CONFIRM' key. Does the message "Operator Error" occur?
