Description:
-This voltmeter uses 0.36inch LED digital tube without casing. The voltmeter is super thin with small shape and low price and stable performances. It can display well.
-This voltmeters measurement range is wide, its DC0-100V. It need outer working power supply and the voltage is DC4.5-30V. There is protection when the wires arent correctly connected.
-This voltmeters display resolution is 0.1V.
-This voltmeter is suitable for clients who has DC power supply,because this can save cost. And it can be used when the voltage need to be measured from 0V.
Precautions
-This voltmeters measurement range is 0-100V, this voltage is just measurement signal and it cant be regarded as voltmeters working power supply. -This voltmeter need outer working power supply which can supply DC4.5-30V as working power supply. About three wires, the black wire is communal negative pole,he white wire is connected to measuring voltages positive pole, the red wire is connect to working power supplys positive pole,the measuring circuit and power circuits negative pole are communal.
-The voltage of this voltmeters working power supply is 4.5-30V,30V is the voltmeters maximum operating limited voltage, please leave enough margin when working, to avoid voltmeters permanent damage because of electrical spark, power supply ripple,or other too high abrupt change of voltage.
-This voltmeter didnt do moisture-proof, waterproof, shockproof, anti-oil processing, please be careful or handle by yourselt when using.
