Feature: Measurement of the current amplification factor and base - emitter threshold threshold voltage of bipolar transistors. Proof of protection diode from bipolar transistors and Mosfets. Measuring the gate threshold voltage and gate capacitance value of MOSFETs. Resistance measurement resolution is 0.1 ohms, 50 M Ohms can be measured Up to two diodes are displayed with the symbol or the symbol in the correct order. Material: Plastic colour: as shown Package Contents: 1 x -328 Transistor Tester 1 x Test Clip cable Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
