5. Návod k obsluze
5.1 Zapnutí/vypnutí
Stiskněte tlačítko Moc tlačítko pro zapnutí nebo vypnutí testeru.
5.2 Výběr testovacího objemutage
Použijte TEST VOLTS button to cycle through available test voltages (250 V, 500 V, 1000 V, 2500 V). Select the appropriate voltage for your application based on equipment specifications and safety standards.
5.3 Performing an Insulation Resistance Test
- Ensure the circuit under test is de-energized and locked out according to safety procedures.
- Připojte měřicí vodiče k obvodu nebo součástce.
- Vyberte požadovaný testovací objemtage pomocí TEST VOLTS tlačítko.
- Stiskněte a podržte TEST button to initiate the insulation test. The display will show the applied voltage and the measured resistance.
- Uvolněte TEST button to stop the test. The measured resistance will remain on the display.
- Allow the circuit to discharge completely before disconnecting the test leads.

5.4 Polarization Index (PI) and Dielectric Absorption Ratio (DAR)
The Fluke 1535 automatically calculates PI and DAR, which are crucial for assessing the condition of insulation over time. These ratios help identify moisture or contamination in insulation.
- DAR: Ratio of insulation resistance at 60 seconds to insulation resistance at 30 seconds.
- PI: Ratio of insulation resistance at 10 minutes to insulation resistance at 1 minute.
To perform a PI or DAR test, select the appropriate function using the FUNKCE a poté stiskněte TEST button. The tester will automatically perform the timed measurements and display the calculated ratio.
6. Údržba
