Description:
The basic performance parameters of the voltmeter are as follows:
Opening Size: Approx. 45mm*26mm
Dimensions: Approx. 48mm*29mm*22mm
Display: Three 0.56 LED digital tube
Display Color: Red / green / blue
Measurement Accuracy: +/- (1% +1 words)
Supply Voltage: DC4.5-30 (independent power supply)
Voltage Measurement Range: DC 0-99.9V.
Display Size: 0.56"
Refresh Speed: 500ms.
Power Supply: DC 4.5V - 28V
Working Temperature: -10° - 65 °
Red line: The power supply is positive, and it needs to be connected to the positive pole of the DC range of 4.5-30V.
Black line: common negative pole, which is both the negative pole of the power supply and the reference negative pole of the measurement.
Yellow line: measurement signal input positive
Note: The header needs to be powered independently. The power supply range is 4.5-30V DC. When the red and black wires are connected to the power supply, the meter will display 0.0. At this time, the measured voltage can be connected between the yellow line and the black line. Voltage range is DC 0-99.9V.
Instruction:
Red Line: Power Supply + (4-30V )
Yellow Line: Measure Voltage +
Black Line: Power Supply -, Measure Voltage-
Package Including:
1 x Digital Voltmeter
