Measurements of Equipment Leakage Current
(a) TN-System (Direct Method)
1. Connect the Safety Analyzer directly to the main power source for a TN-System.
2. Connect the console to the main power socket of the Safety Analyzer.
3. Attached the crocodile clip from the Safety Analyzer lead (Applied Part module port 1) to the proximal end of the tip (without the flue) as
shown in the Figure 7-2.
4. Attached the test lead from the safety Analyzer lead (Applied Part module port 2) to the Equipotential Earth Ground pin of the console as
shown in the Figure 7-2.
5. Select Equipment Leakage Current measurement on the safety Analyzer.
6. Turn on the DUT and wait for the GUI to load.
7. Connect the handpiece, aspiration, irrigation tubing kit, waste canister, and other accessories to the console and cart.
8. Prime the irrigation tubing and perform a handpiece test.
9. On the DUT main menu, set up the system as follows:
• AMPLITUDE to 100%
• ASPIRATION to 100%
• IRRIGATION to 2ml/min
• TISSUE SELECT to OFF
10. Press down the footswitch pedal to achieve maximum stroke.
11. Obtain the Equipment Leakage Current measurement, and normalize the value according to Section 7.8.3 Normalization Instructions.
