2. Saugos informacija
Please read and understand all safety warnings and operating instructions before using the ET271 tester. Failure to do so may result in injury or damage to the device.
- Per ttage Apsauga: The tester has a test range of 3-90V. If the input voltage exceeds 90V, the display will show "overvoltage". Disconnect immediately.
- Apsauga nuo srovės: The tester has a test range of 0-40A. If the input current exceeds 40A, the display will show "overcurrent". Disconnect immediately.
- Apsauga nuo temperatūros: If the internal temperature exceeds 260°C, the display will show "over temperature". Allow the device to cool down before further use.
- Apsauga nuo atvirkštinio poliškumo: The instrument is designed with reverse polarity protection. If the positive and negative poles are reversed during connection, the instrument will not display any readings, preventing damage. Correct the connection before proceeding.
- Apsauga nuo viršįtampių: If the input power exceeds the rated range (2000W), disconnect the device. Use within the specified power limits.
- Ensure all connections are secure before initiating any tests.
- Nebandykite ardyti ar modifikuoti įrenginio.
