Meranie odporu automatického rozsahu digitálneho multimetra
Insert the test leads into the "COM" and "VΩ" holes, turn the knob to the desired range in "Ω", and connect the test leads to the metal parts at both ends of the resistor.
Upozornenie:
1. If the measured resistance value exceeds the maximum value of the selected range, the over-range "1" will be displayed, and a higher range should be selected. For the resistance greater than 1MΩ or higher, it will take several seconds for the reading to stabilize. This is normal.
2. When not well connected, such as open circuit, the meter displays "1".
3. Pri kontrole impedancie testovaného vedenia sa uistite, že ste v testovanom vedení odpojili všetky napájacie zdroje a vybili všetky kondenzátory. Ak sú v testovanej linke napájacie zdroje a prvky na ukladanie energie, ovplyvní to správnosť testu impedancie linky.
4. The 200MΩ gear of the multimeter has 10 characters in short circuit. When measuring a resistance, these 10 characters should be subtracted from the measurement reading. For example, when measuring a resistance, it is displayed as 101.0, and 10 characters should be subtracted from 101.0. The actual resistance value of the measured component is 100.0 or 100MΩ.
5. Počas merania sa môžete dotknúť odporu rukami, ale nedotýkajte sa oboch koncov odporu rukami súčasne - ľudské telo je vodič s veľkým, ale obmedzeným odporom.
