PLT - Patient Earth Leakage Current Test
1.
Let the machine pass FCH.
2.
The safety couplings of the dialysis fluid tubes shall be con-
nected to the safety tester via an accesspoint.
Note!
There must be a main flow during this test. Check that the
Bypass button is switched off.
3.
Measure the patient leakage current with the safety tester.
4.
Take the highest AC-reading when the machine is running.
5.
Take the highest DC-reading when the machine is running.
6.
Invert the phases of the mains voltage. The machine might
restart.
7.
Take the highest AC-reading when the machine is running.
8.
Take the highest DC-reading when the machine is running.
9.
Check that the highest measured readings don’t exceed the limit
values in following table:
NOTE
Make sure that the machine does not perform a taration (self calibration)
during the measurements.
