1. Electric vehicle dual display voltage and current meter head VC288HV(High voltage version 100A red and blue + shunt) 2. Note: For meters above 50A, 100A (including 50A), the current can only be measured after the shunt is correctly connected, otherwise it burn out. 3. High voltage version, DC 7-100V can be tested directly without external power supply. 4. High precision, high reliability, suitable for high-end applications 5. It has reverse connection protection and not burn if it is connected reversely. Voltage measurement range: DC7.0V-100V Current test range: 0-100A Power supply range: DC7.0V-100V Voltage error: ±0.1% Current error: ±1% External shunt specifications: 75 milliohms Working current: Less than 20mA Refresh speed: about 300mS once Display mode: double three-digit 0.28inch LED digital tube Display color: Red + Blue Lead length: 15cm Overall dimensions: approximately 48x29x22 mm (lengthxwidthxthickness); Installation hole: about 46x27 mm Working temperature: -10℃-65℃ Colour:As Shown Material:ABS Package Contents: 1x Digital Voltage And Current Meter Head (With Wire) 1x Shunt Only the above package content, other products are not included.
