Application of new digital multimeter in industry
As one of the indispensable products in the field of electronic testing, digital multimeter has the widest range of applications. A digital multimeter is a measuring instrument that uses the analog/digital conversion principle to convert measured data into digital quantities and displays the measurement results in digital form. Compared with pointer multimeters, the new generation of digital multimeters has the advantages of high precision, fast speed, large input impedance, digital display, accurate readings, strong anti-interference ability, and high degree of measurement automation. Therefore, it is widely used and favored by engineers.
The newly launched digital multimeter DM3000 series adopts dual-mode display, with a maximum resolution of 6 1/2 digits, and has a waveform capture function. Its multiple standard interfaces and Ethernet interface further expand the application of digital multimeters. Scope and application areas.
Troubleshooting helps engineers solve problems
DM3000's data sampling rate of up to 50k/s is currently the highest indicator in the industry. Using this feature, continuous processes that were previously difficult to capture using digital multimeters with slower readout speeds can be completely captured.
In the field of electronic production, sudden failures often occur in product production lines. It is very critical for engineers to find out the cause of the failure and solve the problem in a timely manner. For example, DVD designers often have problems with power supplies burning out during product debugging, causing a lot of inconvenience to product production. Utilizing new A/D technology, DM3000 can achieve a readout speed of 50,000 readings/second, and can continuously send readings directly to a PC at the same speed, with a non-volatile storage depth of 1M bytes. Its Data Log starting trigger condition has multiple setting methods, which is accurate and flexible. The use of true RMS conversion technology can also significantly improve the accuracy of AC voltage measurement, while having an AC bandwidth of 3Hz-300kHz.
Using DM3000, you can use the Data Log function to collect the overcharge phenomenon during the power-on process, and then download it to the PC using USB. Then use the analysis software to display and analyze the collected points, and finally find out the cause of the failure and help engineers solve production problems. practical problems in. In the collection and analysis of rapidly changing audio waveform data, seismic wave data, etc.
Automatic measurement, no one responsible for completing measurement tasks
The first desktop digital multimeter can be used as a separate instrument or equipment, or it can be combined with other equipment to form a complete application system to complete various testing and measurement tasks. In addition, the automatic measurement function of DM3000 also helps engineers complete product inspection.
The automatic measurement function of DM3000 is not available in other similar products. Its internal inspection expansion interface can be connected to different matrix switching modules, and each module can be set with a different ID to facilitate automatic configuration of the system. It supports a variety of host computer software and drivers, making it easy to integrate DM3000 with the system; standard RS-232 and GPIB interfaces and SCPI programming language increase the convenience of integration.
Taking the product aging process in the production process as an example, users can use a 12-channel voltage differential input inspection module and program the DM3000 test program in advance to test 12 independent tested products at a set time. Automatically record point data and automatically generate electronic data reports for production operators to check and analyze product quality and defects to eliminate unqualified products. The most important thing is that the automatic measurement system configured with DM3000 does not require personnel to be on duty, and can realize long-term automatic monitoring and data collection of the measured object.
Digital multimeter detects car faults
When troubleshooting the electrical parts of a car, the most important thing is the reasoning process for the cause of the fault. This process is important. This is because you can't see what's going on inside and you can't take apart a large number of components like mechanical parts. Problems can be discovered quickly using logic and reasonable steps. The key tool in this process is the multimeter.
A multimeter is one of the most commonly used automotive electrical repair tools for testing voltage, current, and resistance. However, the input impedance of the analog (pointer) multimeter used in the early days was too low, which had a great impact on the electronic circuit during measurement. This kind of meter mostly uses 9V voltage when testing resistance, so it can easily damage those sensitive electronic components. But RIGOL digital multimeter DM3000 completely avoids this situation.
