The AT511C is a cost-effective DC low resistance Tester that is an upgraded version of the AT511M.
Compared with its predecessor, AT511M, the AT511C has a wider test range: 0.1mΩ~50.00kΩ, and a maximum display of 5000 numbers. At the same time, the test speed is increased: up to 10 times/sec and stable readings. The improved automatic range test circuit and the design of the all-electronic switch can switch from the highest range to the lowest range instantaneously.
The AT511C uses a 0.8-inch high-brightness digital tube display, full Chinese buttons and indicators, making the instrument display clearer, and the point-and-shoot operation interface is also easy to use.
The AT511C uses superior low current test characteristics, which is especially suitable for resistors that are sensitive to test currents, such as platinum RTD, copper thermoresistor, PTC ceramic RTD, alloy wire DC resistor, DC resistance of current protection devices, etc.
The AT511C is also suitable for measuring a wide range of contact resistances; Winding resistors for transformers, inductors, motors, and deflection coils; wire resistance; metal riveting resistors for vehicles, ships and aircraft; Printing plate lines and porosity resistors, etc.
