MOS Transistor Selector

MOS Transistor Selector  
 Characteristics:
◆Test parameters and ranges: threshold voltage UGS(th): 0.1~9.9V; internal resistance RDS: 0.1~ 9.9Ω;
   transconductance gm: 0.30~5.00S; withstand voltage U(BR)DS: 50~650V
◆Freely setting limit of qualification judgement, automatically saving in case of  any power cut, and
   alarming when measured value exceeds limit
