Features: LCD Display: Large LCD screen with backlit display, high-definition LCD display, Backlight allows for use in low light or dark environments. The backlight can be turned on or off, providing energy-saving options. Measurement Range And Accuracy: The DC low resistance tester features measurement resistance range from 10μΩ to 5kΩ, Resistance accuracy: 0.1%; Minimum resolution 10μ& 8486;. High precision and accurate reading, which meets the needs of electricity and household maintenance. Sorting Result Output Function: The product also has a sorting result output function. If the upper and lower limits/nominal values have been set, the sorting result can be output to the outside through the interface during measurement. The maximum percentage can show-99.99%-99.99%. Multiple Triggering Methods: With multiple trigger modes, continuous trigger means continuous measurement. Manual/external trigger should be selected for single trigger mode. Manual trigger can trigger a measurement by pressing the back key. External trigger needs to be connected with external communication and triggered by external signals. External Port: It is equipped with HANDLER, RS232 communication port to communicate with PC, PLC (RS485 as option), can realize remote control. Application: DC low resistance tester can be used to test various DC medium, low value resistance, including transformer and other winding resistance, relay and other contact resistance, cables and other conductor resistance, connection resistance between metal components, fuse, conductive rubber and other types of DC resistance.
