HW-308 ESR METER TRANSISTOR TESTER

This innovative ESR Meter is designed to measure the equivalent series resistance (ESR) of capacitors quickly and easily. It uses an ATmega8, ATmega168 or ATmega328 microcontroller to calculate the result. The 2×16 character LCD display shows the result. The shutdown current is only 20nA and supports battery operation. The current amplification factor of the bipolar transistor and the threshold voltage of the emitter junction are measured. Darlington transistors can be identified by high threshold voltages and high current amplification factors. For the detection of bipolar transistors, protection diodes for MOSFETs are included. Measure the threshold voltage and gate capacitance of the MOSFET with this device. The resolution of the resistance measurement is 0.1 ohms and the highest measured value is 50 M ohms.
A capacitor can be detected and measured. The highest four digits and units are displayed. The value can be from 25pf (8MHz clock, 50pF@1MHz clock) to 100mF. The resolution is up to 1 pF (@ 8MHz clock).
