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.

Main Technical Parameters
M1: The factory default of M1 multi-display meter is ammeter.When there is no signal input at the current detection end and there is signal input at the voltage detection end, the meter will automatically switch to voltmeter. If there is signal input at both ends, the preferred option is ammeter.
Maximum Power Consumption Of Instrument : 6W
Frequency Range Of Measurement Input Signal : 10~99.9Hz (factory default)
The Sampling Rate : about 100mS
The Measurement Accuracy : + 0.5%
Environment : the temperature is -30~55℃ and the humidity is ≤ 85% RH without corrosion.
Contact Capacity Of Alarm Output Relay : 3A-AC250V/DC30V
