Specification:
• Parameter measured under normal temperature β(0-99)
　　Switching time T(0.01μs-99.9μs),including Tr, Ts, Tf
　　VCES(0-2V),VBE(0-2V)
　　Leakage current ICEO(0.01μA-99.9mA)
　　Withstand voltage BVCEO(50V-650V)
• Parameter measured under high temperature: VBE, β, ICEO
• Compare the measuring results VBE, β, ICEO gotten under normal and high temperature, to　　those changes exceed preset limits, the selector alarms to let operator to pick them out
• Divide T and β into several groups, selector can display group number and alarm when　　measured values of VBE, β, ICEO exceed the limit, indicating the unqualified item.
• Freely adjusting or setting of test conditions according to requirement
A、 β testing: three different Ib:0.1mA、1mA、10mA
B、 Switching time test: 4 Ic different: 0.5A、0.25A、0.1A、0.05A
　the corresponding current Ib:0.1A、0.05A、0.02A、0.01A
C、 Heating condition for transistor:
　 Heating voltage:5 ~ 20V  Continuously adjustable
　 Heating current:0.05 ~ 2A  Continuously adjustable
　 Heating time:0 ~ 9.9s  Continuously adjustable
• Dividing value and limit value freely set, automatically saving to any power cut; the　　instrument can save 20 different setting, choose one setting when using;
• Measured values displayed in four windows, easily read, printable.
