Product Description
1.Product attributes
Specifications:
| NAME | Four and A Half Voltmeter |
Features:
The shape is designed using standard universal dimensions
The lens is pure plane, the characters displayed is very clear, the lens as a circular surface, the characters shown fuzzy, not clear
Line:
All with superb SMT technology, so the consistency is very good
The crystal of the watch is made of high precision, high stability of the quartz crystal, not the kind of low precision, low stability of the ceramic crystal oh .......
The LED digital tube display part of the meter, all the lines on the line with a current limiting resistor, LED digital tube will not appear "some strokes" show bright and dark inconsistency Oh
The head of the power supply part of the reverse protection function, power supply is positive and negative reverse will not burn
