Specifications:
Standard configuration for the host + test hook + locking type line / SMD test seat
Dimensions: 90 * 58 * 23 (mm)
Weight (including attachments): less than 200 grams

Features:
One button operation, automatic shutdown, shutdown current is only about 20nA.
Can automatically detect NPN, PNP bipolar transistors, N-channel and P-channel MOS FET, JFET, diodes, two diodes, low power unidirectional and bidirectional thyristor thyristor.
Automatic identification pin arrangement of components, measuring current amplification factor of the bipolar transistor and the base - emitter threshold voltage.
Protection diodes can detect bipolar transistors and MOS tube, measuring MOS FET gate threshold voltage and gate capacitance.
It can simultaneously measure two resistors and resistor symbol is displayed. Show 4 decimal values in the right.
Resistance Symbol side shows the pin number. So you can measure the potentiometer. If the potentiometer wiper not be transferred to a certain extreme position, you can distinguish the middle and both ends of the pins.
Resistance measurement resolution is 0.1 ohms, 50M ohms can be measured.
Two diodes may be displayed in the correct order and a diode symbol, and gives diode forward voltage.
LED is detected as a diode, its forward voltage higher. Combo LED is recognized as two diodes. Reverse breakdown voltage is lower than 4.5V Zener diode can be identified.
Measurement results show that only a single element.
Measurement time is about 2S, just longer time measuring capacitance and inductance.
Note:
Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the instrument.
