u high voltage ，lower current，accurate 
uleakage current、continuously and arbitrarily set test time，strong adaptation
u at the same time showing the actual measured values (time, voltage, current showing at the same time), unqualified audible and visual alarm      
u manual and remote control test 
u high voltage breakdown protection

u DC input can measure the capacitor withstand voltage、leakage current、high voltage silicon rectifier stack、transistor reverse current and reverse voltagea tractor serves several purposes
