In this condition, EQUIPMENT LEAKAGE CURRENT and APPLIED PART LEAKAGE CURRENT must be done with Alternative method.
9.0 Measurements of Mains Voltage
• With the DMM, measure the mains voltage between phase and neutral lines as well as frequency.
• Record the values in IT0738A.
10.0 Measurements of Protective Earth Resistance
• Record in IT0738A if the main lead is original provided with the Clarity console.
• The Safety Analyzer is connected directly to the mains (TN-System or IT-System).
• The DUT (Device Under Test) mains lead is connected to mains socket on the Rigel 288.
• The earth bond lead is connected from the black 4 mm plug to alternatively 3 different connections on the Clarity console as detailed in the
table below.
• From the Rigel 288 main menu, select Manual Mode –> Earth Bond as shown below:
• Execute the protective earth resistance measurement for each connection below by pressing the green button:
o During the measurement, the main cord shall be flexed along its length. If during the flexing, changes in resistance are observed, it
shall be assumed that the protective earth conductor is damaged or the connections are no longer adequate.
Test Description
Equipotential Earth Ground
Cartridge Door
Handpiece Socket Connector
• Record values in IT0738A.
11.0 Measurements of Equipment Leakage Current
11.1 TN-System (Direct method)
• The Safety Analyzer is connected directly to the mains (TN-System only).
• The DUT (Device Under Test) mains lead is connected to mains socket on the Rigel 288.
• Fit a handpiece, the footswitch, the aspiration and irrigation tubing kit, waste canister, etc. to the console.
• Attached the crocodile clip from the safety tester lead (Applied Part module port 1) to the proximal end of the tip (without the flue).
• Attached the test lead from the safety tester (Applied Part module port 2) to the Equipotential Earth Ground pin of the console.
