SHARING EXPERTISE
2.6_CA-EN_03
Various self-tests are performed during the entire therapy in periodic intervals for the safety of the patient. The
following parameters are monitored:
Fluid weight on the load cell
Blood leak detector (BLD)
Safety air detector (SAD)
Proceed as follows in the case of a failed test:
1. Suppress the acoustic alarm with the
key
2. Follow the instructions on the monitor and determine which test failed.
3. Determine and correct the displayed cause, if possible.
4. Repeat the test by again pressing the
key.
