Specification Brand : Beufee BulletPoint1 : COMMON DESIGN: The Amp meter meter head is a common design, i. E. The ground wire at the measuring end is interlinked with the ground wire at the power supply end (except the isolation meter) BulletPoint2 : CONVENIENCE: The dc voltmeter meter head is equipped with voltage calibration potentiometer, current calibration potentiometer, if there is any error, you can calibrate it, because the error is absolute BulletPoint3 : EASY TO USE: The voltage meter adopts the design of automatic movement of the decimal point, this meter has strong anti-interference ability and fast display refresh rate BulletPoint4 : APPLICATION: It is used to monitor the battery voltage, keep abreast of the battery voltage status, and can also be used for voltage and current measurement of other products BulletPoint5 : WIDE POWER SUPPLY RANGE: The voltage meter is dc3.5 ~ 30v (except the isolation meter), the power supply reverse connection will not burn, please note that the voltage between the thin red and black lines cannot exceed 30v Color : Red ExternallyAssignedProductIdentifier : 7675630094236 IncludedComponents : No ItemName : Amp Meter, YB4835VA DC 0~100V 20A Digital Voltmeter Voltage Meter DC Dual Display Integrated Voltage Amp Meter Digital Voltage Meter with Connect Wires ItemPackageDimensions_Height : 3 centimeters ItemPackageDimensions_Length : 9 centimeters ItemPackageDimensions_Width : 5 centimeters ItemTypeKeyword : clamp-meters Manufacturer : Beufee Material : Lithium battery,ABS MeasurementAccuracy : 0.1mm ModelName : Beufeecxewszbn94 ModelNumber : Beufeecxewszbn94 NumberOfItems : 1 NumberOfLithiumMetalCells : 1 PartNumber : Beufeecxewszbn94 ProductDescription : Specification:

Meter head power supply: two-wire socket Fine _ black line: meter head power supply Fine _ red line: power supply to watch head is positive (note, the voltage between fine red and black line cannot exceed 30V)
Isolation meter (isolated power supply): The meter head power supply end and the test end are completely insulated and isolated from each other, can share one power source in multiple meters, no need is worried about all kinds of interference problems caused by sharing the power supply, suitable for the factory aging test stand, test stand, or other equipment requiring more than one meter head Power supply voltage: DC8-18V
Test end: COM: Test Common End V +: Test positive voltage input A +: Test positive current input end;Because the meter head adopts the common ground design, that is, the ground wire at the measuring end is connected with the ground wire at the power supply end, so it can only be connected between the negative and the negative power supply of the equipment under test, as shown in the following figure, the connection error will burn, (if only do voltmeter use, it is recommended to connect the yellow line with the black line, Prevent the digital flicker of ammeter caused by external interference) Non-shunt _ connection method: suitable for below 20A without external connection.
