DC 2 Wires 4.5~30V Mini LED Dial Display Volt Voltage Panel Meter R9CC

Features:OOTDTYThis 's wiring is simple, it only need to connect two wires, the red wire is to connected to positive pole, the blawire is to connected to negative pole, There is protection when the wires aren't correctly connected, the electric circuit won't beedThis doesn't need external drive working power, it can work with measuring voltage, the working voltage's range is 4.5-30VToreach the best measurement accuracy, this will automatically move the decimal point's position according to the different measuring voltage, When it measures the voltage below 10V, it will display two ps ar decimal point, when it measures the voltage above 10V, it will display one p ar decimal pointThis can be d to measure the storage battery's voltage in motorcycles and cars and also can grasp the storage battery's status, It also can be d to measure other voltageNote:30V is the 's maximum operating limited voltage, please leave enough margin when working, to avoid 's permanent damage beca of electrical spark, power supply rple, or other too high abrupt change of voltageThis didn't do moisture-proof, waterproof, shockproof, anti-oil proceing, please be careful or handle by yours when usingSpecifications:Measuring range: 4.5V-30V DCMinimum Input: DC 4.5VMaximum Input: DC 30VAccuracy: 1%(+/- 1word)Display Type: 3 0.36" LED tubeDisplay Color: Red/Blue/GreenRefresh speed: About 200ms/timeCurrent consumption: le than 20mA, usually 5-15mAWorking temperature: -10℃~65℃Dimensions: 34x23x17mm/1.34x0.91x0.67" (LxWxT)Opening Size: 30x20mm/1.18x0.79"Quantity: 1 PcNote:Please allow 1-3mm error due to manual measurement. pls e sure you do not mind before you bidDue to the difference between different s, the picture may not reflect the actual color of the item.
