AK 98™ Dialysis Machine - Functional check 267
Conditions Evaluations & Actions Error codes
Concentrate connected The protective system
measures the conductivity
(conductivity P). If it is
unstable, repeat the test until
error code is generated.

Concentrate connected The protective system
measures the conductivity
(conductivity P). If it is lower
than 17 mS/cm, repeat the test
until error code is generated.
0511 088 025
Concentrate connected The conductivity values are
compared. If the difference is
higher than the limit (see
below), repeat the test until
error code is generated.
0511 088 024
Concentrate connected If the high conductivity test is
not passed within 20 minutes
the error code is generated.

Table 12-31. Limits for the Conductivity test:
*(only performed in Bicarbonate mode)
After the approval of the test, the AK 98 dialysis machine will wait for the conductivity
to drop below 2mS/cm. This will trigger the start of BiCart cartridge priming.
When the BiCart cartridge priming is finished, the machine starts to regulate the
conductivity to the set value.
12.7.7 Degassing pressure test
12.7.7.1 Test objectives and conditions
The two main objectives of the degassing pressure transducer test are:
● To verify that the degassing pressure reading is stable.
● To perform a correlation test between the degassing pressure transducer and the
HPG.
The HPG and PD transducer readings were correlated earlier in the functional check -
in the DIVA/TAVA/EVVA Valves leakage test.
In this test (degassing pressure test) the HPG and degassing pressure transducer
readings are correlated.
The test conditions are set up by stopping the flow pumps and by closing BYVA, DIVA,
REVA, AIVA, ZEVA, HBVA and then opening INVA.
