5:Use 12864  liquid crystal display with green backlight  

Specifications: For you reference  

1,One -button operation, automatic shutdown .  

2,Only 20nA shutdown current.  

3,Automatically detect NPN, PNP bipolar transistors , N -channel and P -channel MOS FET, JFET , diodes , two diodes, thyristors small power unidirectional and bidirectional thyristor.  

4,Automatic identification components pin arrangement .  

5,Measuring bipolar transistor current amplification factor and base - emitter threshold voltage.  

6,Via the base - emitter threshold voltage and high current amplification factor to identify Darlington transistors.  

7,Can detect bipolar transistors and MOS transistors protection diodes.  

8,Measuring the gate MOS FET threshold voltage and the gate capacitance.  

9,Can simultaneously measure two resistors and resistor symbol is displayed. Displayed on the right with a decimal value of 4 . Resistance symbol on both sides shows the pin number. So you can measure the potentiometer. If the potentiometer wiper is not transferred to an extreme position , we can distinguish the middle and both ends of the pin.  

10,Resistance measurement resolution is 0.1 ohms , 50M ohms can be measured .  

11,Can measure capacitanceCan measure capacitance of 30pF-100mF , resolution 1pF.  

12.2uF more capacitors can simultaneously measure the equivalent series resistance ESR values. The two can be displayed with a decimal value , resolution 0.01 ohms.  

13,Can be in the correct order and the diode symbol display two diodes , and gives the diode forward voltage.  

14.LED is detected as a diode forward voltage higher . Combo of the LED is identified as two diodes.  

15,Eeverse breakdown voltage is less than 4.5V Zener diode can be identified.  

16,Can measure a single diode reverse capacitance. If the bipolar transistor connected to the base and collector or emitter of a pin , it can measure the collector or emitter junction reverse capacitance .  
18 can be obtained with a single measurement rectifier bridge connection.

Notice: Before measuring capacitance , the capacitor must be discharged , otherwise very likely damage the meter 

Note:

In order to protect the safety of your product, the test capacitor must be discharged first to avoid electrostatic breakdown of the chip and burn the product.

Transistor Detection:

After the power-off state or test is completed, put the test component into the transistor test area of the test socket, press the lock handle,
press the multi-function key, the tester automatically measures, and the measurement result is displayed at the end of the test.
Warning: We do not recommend using a tester to measure the battery! The battery voltage must be less than 4.5V, otherwise the tester may be damaged!
