Figure 17: Measurement points on the device
Action 1. Perform a visual inspection of all components and cables to
ensure they are in proper condition.
2. If there are doubts about the effectiveness of the insulation
(such as multiple triggering of the fault circuit interrupter or
other protective devices in the physician's practice, or traces of
liquid on the device which suggest the penetration of liquid),
measure the insulation resistance with a test voltage of 500 V.
ð
The measured value may not be less than 7 MΩ.
3. After this, the device leakage current must be measured. The
differential current method should be preferably used. The
device should be in operation during measurement. Press the
measuring tip onto the measurement points shown in the
figure.
ð
The measured value may not exceed 0.1 mA.
