ESR02 pro Digital transistor SMD Components tester Diode Triode Capacitance Inductance Multimeter ESR Meter.


This instrument is an instrument developed for electronics engineers, developers, electronic repair, production plants and enthusiasts.

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.

Support calibration function, you can choose to have original test clips.


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 (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.


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.

Package weight: 0.25 kg Package Size(L x W x H): 17.50 x 10.00 x 6.00 cm / 6.89 x 3.94 x 2.36 inches.
