The digital voltage ampere meter uses a high-precision analog-to-digital converter (ADC) to measure voltage and current, and can accurately measure actual voltage and current values. The LED digital tube display can clearly display the voltage and current values, making it easy for users to read.
The digital ammeter can be controlled through buttons to set and adjust different parameters to meet the different needs of users. It has functions such as overload protection , which can effectively protect the safety of the circuit under test and the instrument itself.
The digital panel meter adopts a compact and lightweight design, making it easy to carry and use.
LED digital display voltage and ammeter are widely used in various occasions where voltage and current need to be measured, such as laboratories, industrial production sites, etc. It can provide accurate measurement results, and has the advantages of easy use, simple operation, and intuitive reading.
