Panel Meters

Panel meters are instruments used to measure a wide range of electrical quantities, such as AC and DC voltage, AC and DC current, and resistance. They are used in many industries, such as automotive, power and data transmission, and instrumentation. One type of panel meter is the DK791. This article will discuss the application field and working principle of the DK791.

Application Field

The DK791 is a panel meter used to measure AC and DC voltage and current, as well as resistance. It can be used for a variety of applications, including power and data transmission, instrumentation, and automotive. It is also used in research and development, such as for testing and prototyping. As it is a high-precision panel meter, it can be used for high-accuracy measurements.

Working Principle

The DK791 uses an analog-to-digital conversion (ADC) technique to measure AC and DC voltage and current, as well as resistance. It uses an ADC to convert an analog signal into a digital signal. The digital signal is then sent to a controller, which processes the signal and displays the result on the display. The ADC can be adjusted to measure a range of voltages and currents. The resistance measurement is done by using a Wheatstone bridge, which compares a known resistance with an unknown resistance. The voltage and current are then compared and the result is displayed on the panel.

Conclusion

The DK791 is a type of panel meter used for a wide range of applications. It uses an analog-to-digital conversion technique to measure AC and DC voltage and current, as well as resistance. It is used for power and data transmission, instrumentation, automotive, research and development, and more. It is a high-precision panel meter and can be used for high-accuracy measurements.
