Parameter measured under high temperature beta, V_be, I_ceo .Compare the measuring result beta, V_be, I_ceo  gotten under normal and high temperature, to those changes exceed preset limits, the selector alarms to let operator to pick them out. Freely adjustment or set of testing condition according to requirement Beta ,Switching Timing Test I_c , I_b 

The system uses 12 bits super speed A/D, the biggest speed of sampling is 10MHz, exactly test the rest magnet, biggest magnet density, Br/Bm, swing magnet conductance, magnetic core spoilage, B-H. The frequency can be consecutively adjusted  in 20kHZ-200kHZ.Measure relative value of magnetic permeability Mew m. No need of wiring, directly testing, being convenient. Mutual inductance testing automatic selecting out of limit alarming.

Variable DC regulated stabilized output of 0-30volts,0-2A/5A/10A line regulation of +/-0.05%,load regulation of +/-0.05% no load to full load. DC regulated power supply are constant volts, current limit type supplies have high regulation or load and line voltage variation. The supply are protected against short-circuit, over load. The output current can be limited to any value from 0 to max.. 

Latest technology based servo voltage stabilizers to stabilize output  1% regulation for  variation in main voltage 160 to 260 voltage or 170 to 270 voltage and load regulation.

To test the" resistance to fire" in moulded insulator parts of CFL, electrical accessories, switches, ELCB, MCB etc. Stimulates thermal stresses which may produce source of heat and ignition. It analyses the Fire hazards, the product takes place.

To test lamp, correctly positioned  relative to the major access of the cap flange, light center length within the specified limits.
