4. Language/Settings: Navigate through the menu to set your preferred language and other basic settings if prompted.

5.2 Падключэнне вымяральных правадоў

For insulation resistance measurements, connect the test leads as follows:

• Connect the red test lead to the 'L' (Line) terminal of the tester.
• Connect the black test lead to the 'E' (Earth) terminal of the tester.
• For three-wire measurements, connect the blue test lead to the 'G' (Guard) terminal.
• Attach the crocodile clips securely to the test leads and then to the object under test, ensuring good contact.

5.3 Basic Insulation Resistance Measurement (RISO)

1. Выберыце рэжым: Use the rotary switch or menu to select the 'RISO' measurement mode.
2. Set Test Voltage: Adjust the desired test voltage (e.g., 500V, 1000V, 5000V) using the appropriate controls.
