Digital panel meters are used to display an input signal, and measure current, voltage, and frequency. They are equipped with bright LED displays for display only or set point control options. Many panel meters also include alarm options as well as the ability to connect and transfer data to a computer.
Since panel meters are generally mounted inside an instrument panel, the panel must be cut to accommodate the panel meter. In order to provide interchangeability between panel meters, most panel meters are designed to standard DIN sizes. Large display panel meters are commonly used when the display must be visible at a distance.
Benefits & Applications:
• Accuracy is typically .5% or better
• Monitors and measures voltage and current
• Large digital displays for AC & DC application
• External or loop power required
In the past, most measuring instruments utilized an analog panel meter in displaying the measured information. Analog panel meters are quite economical; however, the non-linearity in the analog meter movement can produce errors. In addition, analog panel meters have reading errors and parallax problems. Due to the small size of the meter screen, analog panel meters are hard to accurately read. One benefit of a digital panel meter is that it provides a high level of accuracy and can be easily read with little or no ambiguity in the reading. A digital panel meter is provided with an LED display of certain digits corresponding to the length of output parameters. Some digital panel meters can be calibrated to read out in any desired dimensional units. 
Designed for process signals such as 4-20 mA and 0-5 or 0-10 V that require zero and span adjustment, >Product News Network</ref>
One digital panel meter can be made to display several stored input voltage values being held by a voltage hold signal. 
A fast acting digital panel meter, which can measure and store the peak value of an impact force. The idea for the new panel meter began when a manufacturer of body armour for the forces had an unusual request. The company wanted to clearly demonstrate the resilience of its product in a dramatic way. In a mock attack, a hammer wielding assailant would try his best to overcome a member of staff protected by the body armour. The hammer contained a force transducer, which generated a fleeting signal, proportional to the force of the blow. This signal was connected to the new panel meter, which displayed the peak impact force, and stored the value in memory. Because the peak signal is present for a fraction of a millisecond, and an accuracy of better than 0.5% was required. Because there are many other similar applications in the testing industry, particularly in destructive testing,
