Line 13 CONDUCTIVITY
1. Switch to the debug screens by pressing and holding the [
same time for approximately 1 sec. The main display will change indicating that
the machine is in debug mode.

2. Use the [
3. On debug screen #0, locate the ACID and the BIC data boxes. Record the ACID
STEPS (ACID data box) and BICARB STEPS (BIC data box) on the installation
Checklist in their appropriate places.
4. On the Dialysate screen, the TCD value is the expected conductivity. Record this
value on the Installation Checklist under EXPECTED.
5. Verify that the dialysate conductivity measured by the machines internal
conductivity cell agrees with an external meter within 0.1 mS/cm as follows:
a. Connect an external conductivity meter to the dialysate lines.
b. With the machine in Dialysis mode, out of bypass, and the flow ON, compare
the value shown on the external meter with the conductivity shown on the
Home screen. They must be within 0.1 mS/cm of each other.
c. Record ACTUAL and DISPLAYED conductivity on the Installation Checklist.
Line 14 VERIFY pH IS APPROX.7.3 -Record pH
1. Place the machine into dialysis mode and allow it 10 minutes to stabilize.
2. Use a pH test strip (P/N 335130-01 or equivalent) to verify the dialysate fluid is
approximately 7.3.
3. Record the measured value on the Installation Checklist.
Line 15 PERFORM PRESSURE HOLDING TEST AND ALARMS TEST.
1. Place the machine into dialysis mode and allow it 10 minutes to stabilize.
2. With the machine stable, alarm free and dialysate lines on the shunt, select the Test
& Options screen tab. Press the Both Tests button and allow machine to run
through the autotest. The Test complete message will be displayed when test is
finished.
