电子扭矩测量仪采样保持电路初探（1）

采用分段检测法，给扭矩仪施加恒定力矩信号，从信号输入级开始分段检测，检查检测级的输出信号是否正常。通过检测，前面的电路均正常。考虑到峰值电容的峰值保持作用，用万用表检查保持电容，果然是坏的，更换保持电容，仪器恢复正常。

Studies of the Locking Circuit of Electronic Torque Vibration Measuring Cells(1)

Panel detection method is used to apply constant moment signals to the cell.Detection begins from the signal input sectionally for the purpose of checking whether the input signal is normal.The detection shows that the preceding circuits are normal.In consideration of the peak value holding of the peak electric capacity,a multimeter is used to detect the holding capacity.If it is broken,change the capacity to get the instrument work normally.
