The Taidacent Ohm Meter is designed to provide accurate resistance measurements with ease. It operates on either DC5V or DC12V, ensuring versatility for different needs while consuming less than 50mA of current. This device is a common ground instrument, which means the power supply and signal share a connection; for best results, using a separate power source is advised. Importantly, never attempt to measure resistance while power is applied, as this could damage the meter. Additionally, selecting the correct measurement range is crucial; choosing too high a range may lead to inaccurate readings of small resistances.

The Taidacent Ohmmeter is a versatile resistance measuring tool that operates on a DC5V or DC12V power supply, consuming less than 50mA of current. It is important to use a separate power source to avoid damage, as this device cannot measure resistance while electricity is applied. Moreover, selecting the correct resistance range is crucial for accurate readings, especially for small resistances. The common ground design ensures that the power supply and measurement terminals are isolated, enhancing safety and reliability during use. This ohmmeter is perfect for users looking for precise resistance measurements in various applications.

Taidacent Ohm Meter Resistance Tester, also known as Taidacent Ohm Meter, is a digital DC resistance measuring instrument for measuring resistance. It has two optional power supply modes, DC5V and DC12V, with a current consumption of less than 50mA. As a common ground instrument, it is recommended to use a separate power supply that is not related to the signal. The meter head is also a common ground instrument and it is recommended to use a separate, independent, and isolated power supply. To ensure accurate measurements, select a suitable range and avoid measuring with electricity to prevent the meter from being burnt out. With its convenient features, Taidacent Ohm Meter can provide reliable and accurate resistance measurements for various applications.
