Resistance Measurement Principle: The DC Resistance Meter operates based on the principle of Ohm's law, which states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance. The meter applies a known DC voltage to the component or conductor under test and measures the resulting current. By using Ohm's law, it calculates the resistance value.

On the basis of rich experience in impedance test and wide market research, now Tonghui launches the new DC impedance measurement instrument with touch and LCD screen ---TH2516 DC Resistance meter. TH2516, with elegant appearance, easy operation and excellent performance, is comparable to the most advanced products in the market.
TH2516 adopts 32 bits CPU and high density SMD technology.24 bits, 4.3-inch and touch LCD screen brings ease for your eyes and convenience to your operation. The maximum 0.05% accuracy and minimum 1 resolution shore up its leading role in testing relay contact resistance, interconnecting resistance, conductor resistance, PCB resistance and weldinghole resistance.
Temperature compensation and conversion functions make your tests be free from the effect of the environment temperature. The offset voltage compensation has effectively eliminated the electromotive force of the DUT and its contact potential difference. For the contact influence of the thermoelectricity on DUT, its elimination is achieved.
Automation on production lines can be greatly improved by the realization of ultra-high test speed and the signal output of 3 compare results through HANDLER interface.
