Multifunction Transistor Tester ESR02pro Smart ESR/SMD Diode Triode Capacitance Resistor Meter MOS/PNP/NPN Test with Test Clip
It is very easy to test plug-in and SMD devices, also can test different kinds of diodes, triodes, thyristors, MOSFET, enable to analysis the device type, the polarity of the pin, the output HFE, the valve voltage, the junction capacitance of the FET.
Features:
1. Two button operation, automatic shutdown.
2. Only 20na off current.
3. Automatically detect NPN, PNP bipolar transistors, N-channel and P-channel MOS field effect transistors, junction field effect transistors, diodes, diodes, thyristors, low-power unidirectional and bidirectional thyristors.
4. Automatic identification of component pin arrangement.
5. Measurement of current amplification factor and base-emitter threshold voltage of bipolar transistors.
6. Identify Darlington transistors by base emitter threshold voltage and high current amplification factor.
7. Can detect bipolar transistors and MOS transistor protection diodes.
8. Measurement of gate MOS FET threshold voltage and gate capacitance.
9. It can measure two resistances at the same time and display the resistance symbols. The right shows a decimal value of 4. The resistor symbols on either side show the pin number. So you can measure the potentiometer. If the potentiometer wiper is not shifted to the extreme position, we can distinguish between the middle and the ends of the needle.
10. The resistance measurement resolution is 0.1Ω, and it can measure 50MΩ.
11. Can measure 325pf-100mf capacitance with a resolution of 1pf.
12.2uf more capacitors can measure the equivalent series resistance value at the same time. Both can be displayed as decimal values with a resolution of 0.01Ω.
13. Two diodes can be displayed in the correct order and diode symbol, and the diode forward voltage is given.
14. LED is detected as diode with high forward voltage. The combination of LEDs is determined to be two diodes.
15.eeverse breakdown voltage is less than 4.5v Zener diode can be identified.
16. A single diode reverse capacitance can be measured. Collector or emitter junction reverse capacitance can be measured if a bipolar transistor is connected to the base and the collector or emitter of the pin.
17. Can be connected with a single measurement rectifier bridge.
Specification:
Resistance: 0Ω-50MΩ. Resolution: 0.01Ω.
Capacitance: 25pf-100mf Resolution: 1pf
Inductance: 0.01mH-20H. Resolution: 0.01mH
Measuring capacitance ESR resolution: 0.01Ω
Things to note:
Before testing the capacitor, be sure to discharge it, otherwise it may damage the internal circuit.
If using DC supply, please choose DC 9V-12V adapter (including 9V and 12V).
Can be powered by a 9V 6LR61 battery (the battery not included), when the battery power is under 6V, please replace a new one.
How to use instructions:
Push "POWER / TEST" to power on and start a test, multiple measurements can be repeated by this key, auto power off 20 seconds after measurement.
Provide three kinds of socket, each socket pin 1, pin 2 and pin 3 are connected.
There is a table "typical ESR value of electrolytic capacitor" at the back, it is for guiding only, these are typical value for standard grade electrolytic capacitor at room temperature.
Calibration:
Short the test pin 1, 2, 3 together and push "POWER / TEST" button, then the screen prompts to enter calibration, push the button again within 2 seconds to confirm. Few seconds latter the screen prompts to release pin 1, 2, 3, release them and wait for calibration finish.
Note:
1. Due to the light and screen difference, the item's color may be slightly different from the pictures.
2. Please allow 1-3cm differences due to manual measurement.
