Fig. 4: Measuring circuit for measurement of the patient leakage current in a type B application
part with a protective conductor in compliance with DIN VDE 0751-1/2001-10, Fig. C10.
Pos. 1 = System
Pos. 2 = Application part type B
Pos. 3 = Measurement setup (integrated into measuring device)
The system must be switched on during measurement. Measuring devices with auto-
mated measuring sequences must therefore be set to manual measurement.
The same measuring conditions as in the first measurement apply.
The values determined in the repeat measurement, including the application parts/mea-
suring points, must be recorded and assessed in the patient leakage current report.
The values for each application part may not exceed the permissible leakage current val-
ues according to DIN VDE 0751-1/ 2001-10, table F.1, line "patient leakage current" of
0.01 mA for direct current and 0.1 mA for alternating current.
Document the measuring procedure and the measuring device used (designation and
serial number).
In the case of repeat measurements, the measured values must also be evaluated.
NOTE
For evaluation purposes, the first measured value and the values
documented during maintenance or safety checks must be com-
pared to the measured values. A sudden or unexpected increase
in the measured values may indicate a defect in the system (pro-
tective conductor connection damage, insulation damage, dam-
age from moisture, etc.) - even if the limit value of 0.01 mA for
direct current and 0.1 mA for alternating current is not exceeded.
The evaluation is not necessary in the case of a new determination.
