Applications of new digital multimeters in industries
Automatic measurement, unmanned completion of measurement tasks
A high-end desktop digital multimeter can be used as a standalone instrument or combined with other devices to form a complete application system to complete various testing and measurement tasks. In addition, the automatic measurement function also helps engineers to complete product testing very well.
The automatic measurement function is not available in other similar products. The internal inspection extension interface can be matched with different matrix switching modules, and each module can be set with a different ID, making it easy to achieve automatic system configuration. It supports multiple upper computer software and drivers, making it easy to integrate DM3000 with the system; The standard RS-232 and GPIB interfaces, as well as SCPI programming language, further enhance 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 to program the DM3000 testing program in advance, which can test 12 independent tested products at the set time, automatically record point data, and generate electronic data reports for production operators to inspect and analyze product quality and defects, in order to eliminate unqualified products. More importantly, the automatic measurement system configured with DM3000 does not require personnel to be on duty and can achieve long-term automatic monitoring and data collection of the measured object.
Digital multimeter for detecting car faults
When troubleshooting the electrical components of a car, it is important to infer the cause of the malfunction. This process is very important. This is because you cannot see the internal situation and cannot disassemble a large number of components like mechanical parts. By utilizing logic and reasonable steps, problems can be quickly identified. The key tool in this process is a multimeter.
A multimeter is one of the commonly used automotive electrical maintenance tools, used to test voltage, current, and resistance. But the input impedance of the analog (pointer) multimeter used in the early days was too low, which had a significant impact on the electronic circuit during measurement. This type of meter mostly uses 9V voltage to test resistance, so it is easy to damage sensitive electronic components. But the RIGOL DM3000 digital multimeter completely avoids this situation.
Its input impedance is high, and its accuracy and safety are superior to analog meters. The voltage during resistance measurement is also low, so it will not damage the components of each sensor. But there is also a problem with general numerical tables. It cannot display information on the increase or decrease in measurement readings. During exhaust emission testing and engine analysis, it will be found that pure digital meters cannot provide stable change values. DM3000 overcomes the shortcomings of digital meters and replaces them with analog/digital combination meters. It has the advantages of both digital meters and analog meters for dynamic measurement.
