Description
-This voltmeter uses 0.36inch LED digital tube without casing.
The voltmeter is super thin with small shape and stable performances.
-This voltmeter’s measurement range is wide, it’s DC0-100V.
It need outer working power supply and the voltage is DC4.5-30V.
-This voltmeter’s display resolution is 0.1V.
Precautions
-This voltmeter’s measurement range is 0-100V, this voltage is just measurement signal and it can’for t be regarded as voltmeter’s 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 voltage’s positive pole, the red wire is connect to working power supply’s positive pole, the measuring circuit and power circuit’s negative pole are communal.
-The voltage of this voltmeter’s working power supply is 4.5-30V,30V is the voltmeter’s maximum operating limited voltage, please leave enough margin when working, to avoid voltmeter’s permanent damage because of electrical spark, power supply ripple, or other too high abrupt change of voltage.
-This voltmeter didn’for t do moisture-proof, waterproof, shockproof, anti-oil processing, please be careful or handle by yourselt when using.
