Introduction:
VA56 ambient vibration analyzer is a high intelligent pocket measuring instrument.It can measure W.B.z(also named environmental vibration level),
W.B.x-y and Lin.It can meet the requirements of human response vibration meter and GB/10071
128×64 dot matrix LCD display,with background light,USA menu,abundant content,USA tips function,easy to operate.The measuring result can be stored in the analyzer for a long time,and can be print through the RS-232 interface by the micro printer or be send to a computer to be conducted.
