Specification Brand : JZGDX BulletPoint1 : Oscilloscope Probes BulletPoint2 : Red line: The positive pole of the power supply needs to be connected to the positive pole of the power supply within the DC range of 3.5-30V. BulletPoint3 : Black line: Common negative electrode, which is both the power supply negative electrode and the reference negative electrode for measurement. BulletPoint4 : Yellow line: measurement signal input positive pole BulletPoint5 : Note: The meter needs to be powered independently. The power supply range is DC 3.5-30V. When the power supply is connected between the red and black wires, the meter will display 0.000. At this time, the voltage to be measured can be connected between the yellow wire and the black wire. Voltage range is DC 0-33.000V Color : One Color ExternallyAssignedProductIdentifier : 9495569287992 ItemName : Five-Digit Voltmeter Over Four and a Half Digit multimeter Digital Display Voltmeter Head DC LED Digital Display (Size : Red) ItemPackageDimensions_Height : 1 centimeters ItemPackageDimensions_Length : 3 centimeters ItemPackageDimensions_Width : 2 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : oscilloscope-accessories Manufacturer : JZGDX MeasurementAccuracy : 1 ModelName : JZGDX ModelNumber : JZGDX NumberOfItems : 1 PartNumber : JZGDX PowerSourceType : Ac ProductDescription : Oscilloscope Probes Type: Digital voltage measuring instrument Model: 5-33.000V Measuring range: DC0-33.000V Input voltage: DC3.5-30V Output voltage: DC3.5-30V Ambient temperature: 25 Weight: 25 Overall dimensions: 48mm*29mm*21mm Voltage measurement error: ±(0.3‰+2 words) Specifications: red Unit weight: 0.03kg The basic performance parameters of the voltmeter are as follows: Measuring range: DC0-33.000V Display: five-digit 0.36LED digital tube Display color: red Refresh speed: >5 times per second Measurement accuracy: ±(0.3‰+2 words) {meaning that the maximum error of the meter in the worst case is within 10mv and the normal error is within 2mv} Power supply voltage: DC3.5-30V (independent power supply) Working temperature: -10℃~65℃ Opening size: 45.5mm*26.5mm (open the opening to directly snap the watch into the panel) Overall dimensions: 48mm*29mm*21mm Temperature coefficient: less than 25PPM/℃ ProductSiteLaunchDate : 2024-03-09T03:18:24.804Z Size : Red UnitCount : 1 UnspscCode : 43211900
