GEST-123 Conductor Resistivity Tester Introduction: Conductor resistivity tester consists of isolated voltage source, constant current source, analog signal amplification, data processing part, TFT LCD touch display, capacitive touch key board and other parts. Display, setting and adjustment are all on the front panel; input and output ports, power switches and power input sockets are all installed on the rear panel. fulfill the standard: Test methods for electrical properties of wires and cables - Part 2: Resistivity test of metallic materials GB 24525-2009 Determination method of resistivity of carbon materials GB-T 19289-2003 Measurement method of density, resistivity and stacking coefficient of electrical steel sheet (belt) JB-T 6773-1993 Metal Graphite Products - Resistivity Test Method 1 Features: 1. LCD multi-screen display, strong human-computer interaction, full touch data input and data switching display. The screen body part of the touch screen is a multi-layer composite film that is very compatible with the surface of the LCD display. A layer of glass or plexiglass is used as the base layer, and the surface is coated with a layer of transparent conductive layer (ITO film), which is covered with a layer of outer surface hardening. The treated, smooth, scratch-resistant plastic layer is also coated with a transparent conductive layer on its inner surface, separated by a number of small (less than one thousandth of an inch) transparent separation points between the two conductive layers. As the latest computer technology, touch screen is the most advanced and convenient human-computer interaction input device. Using this technology, we only need to touch the icons or texts on the display with our fingers. operation, making human-computer interaction more straightforward. 2. Innovative design using the latest capacitive touch keyboard CTS technology, with rich touch and sound, simple operation and elegant appearance. 3. The test data of the instrument sample can be automatically calculated and processed, and it conforms to the GB/T3048.2-2007 standard. If the communication software is used, it can also be connected with the microcomputer to realize the computerized management. The internal circuit adopts dual microcomputer processors, 24-bit high-performance AD converter, high intelligence, superior performance, high measurement accuracy, good reliability, easy operation and many other characteristics. 4. The instrument adopts a full-panel adjustment operation, and there is no need to open the instrument for any in-machine adjustment. User operation is easy to learn and easy to remember.
