improves the measuring efficiency, reduce the operating personnel
As the strength. The technology used on "four ends" measurement,
eliminate the measurement errors caused by the lead resistance
and contact. With over-voltage protection function, can prevent the
electric potential impact. Panel printer can quickly print
measurement results (selection). Small size, light weight, easy to
carry.
Measurement and analysis of the utility model is suitable for all
kinds of inductive low resistance power transformer, transformer
winding etc.
