AT518 handheld DC low resistance Tester is a high-precision wide-range, high-performance 32-bit ARM microprocessor control of fully automatic real-time detection of micro handheld instrument, in any occasion to achieve accurate and convenient measurement of passive components for a long time. The instrument can test the resistance of 10μΩ~20MΩ, and the maximum number of displays is 20000. It has a current test mode, which can be adapted to different requirements of the test. It is equipped with Mini-USB communication interface for remote control and data acquisition and analysis. AT518 adopts 3.5" high-definition LCD large screen display, large font display is more convenient for you to read data, and the built-in high-capacity lithium battery can be used for a long time standby, which is more convenient for you to take mobile measurements for a long time.
The AT518 handheld low resistance Tester can measure a variety of high, medium and low value resistors; The instrument has a built-in temperature compensation module, which can compensate the temperature of temperature-sensitive devices. The AT518 handheld low resistance Tester can easily measure various switch contact resistances; Connector plug-in resistor; relay wire wraps and shock resistors; Winding resistors for transformers, inductors, motors, and deflection coils; wire resistance; Metal riveting resistors, printed board lines and porosity resistors for cars, ships, and airplanes.
