2、 Overview
2.1 Basic functions and standards:
JG2511C multifunctional digital milliohmmeter is a multi-purpose comprehensive measuring device that uses the four terminal measurement principle to test DC resistance. It can measure the resistance of resistor bodies, low and medium resistance of metal conductors, and contact resistance of switches.
2.2 Complete instrument composition: The instrument consists of JG2511C milliohmmeter host, four terminal test fixture, and PC software. The host mainly consists of a CNC constant current source, high-resolution ADC, keyboard input, display driver, and embedded microcontroller system.
2.3 Advantages and characteristics:
1: Test result classification prompt function: This tester automatically classifies test results, and if it meets the requirements, there will be an audio prompt. There are two options for product classification: absolute upper and lower limit method and standard value plus percentage error band method.
2: Optional intelligent analysis PC software: Convenient to save current data in real-time to the upper computer database, convenient for on-site and future queries, statistics, analysis, and printing reports. Especially suitable for traceability and quality control of testing data on production lines.
3: The instrument is easy to operate and has stable performance: all parameter settings and function conversions are input using digital keyboards, which is simple, reliable, and eliminates the instability and interference of analog potentiometers.
4: Diverse functions and easy selection: instrument operation, can be connected to PC software, or can be operated separately from a PC; Offline or software mid range conversion, with manual/automatic options available.
5: The functions of the instrument are easy to expand: the testing range can be expanded; For the classification result prompt method, synchronous isolation relay signal output can also be used to facilitate functional expansion; PC software can save data automatically or manually, and can also be controlled with a foot pedal. As shown in Figure 1.3. It is also possible to open the instrument communication protocol and integrate the instrument as a modular embedded resistance instrument into the resistance testing system, achieving specialization and modularization of key components, and improving design efficiency and efficiency.

2.4 Fixture selection:
1: General configuration: Four terminal testing fixture, which can test the resistance of two terminal or lead type resistors or switch contact resistance.
2: Special or professional configuration: such as transformer inductive load, multi-channel synchronous testing, etc.
2.5 Scope of application: The instrument has the characteristics of high measurement accuracy, high sensitivity, good stability, high intelligence, compact structure, and simple measurement. The instrument is suitable for testing the resistance performance of resistors and switch devices in scientific research institutions and universities. Especially suitable for situations that require rapid measurement of low to medium resistance and result sorting.
