MK-328 Multi component tester (Transistors NPN PNP MOS, Capacitor ESR, Inductance, Resistor, diodes)

This meter is an intelligent semiconductor device analyzer, it can measure most of the diodes, bipolar
Transistors, Junction/MOS FETs and low power thyristors. It automatically identifies the type of devices and Pinouts, measures the current gain HFE, gate threshold and FET junction capacitance, a typical application is to pair two transistors or identify an unknown SMD device.
Test clips can be connected any way round, the
Pinout can be identified and displayed on screen vs. test clip numbers. Beside the semiconductor device analyzer, this meter can also work as a RLC/ESR meter, the RLC/ESR accuracy may not be able to compete with the professional one, but it definitely meets the needs for most of the applications. A 9V battery (part number 6F22) is used for this meter.





①: LCD screen, to display measured data
②: Test/power-on button. When this button is first pushed, it turns on the meter power and excuses a measurement. After that, every push, it will excuses a measurement. The meter will turn off the power automatically if you don’t use it within 20 seconds
③: Test terminal 1, Yellow, will display as pin 1 on LCD.
④: Test terminal 2, Green, will display as pin 2 on LCD.
⑤: Test terminal 3, Red, will display as pin 3 on LCD.

Test clips
For those big size device under test (DUT), you may connect them directly to the test terminals,
Otherwise, you need the test clips. You can hook up the clips any way round, the meter will identify and display the pinout.



Test jig
Used for small pin pitch and thin pin lead device, such as low power transistor, Resistor and capacitors, It also have test area for SMD devices. 



 At work!

  1. HELLO MR. HUMPHREY, I HOPE YOU ARE WELL AND SOUND. I AM MR. LALIKA, AN ELECTRONIC REPAIRER FROM IRINGA TANZANIA. I HAVE BEEN PASSING THROUGH YOUR EVERY LESSON YOU SHARE WITH US TO EVERY CORNER OF THE NET AND I HAVE BEEN LEARNING A LOT FROM THEM. THANKS FOR THEM, AND YOUR EFFORT AND TIME ARE DEEPLY APPRECIATED AND HIGHLY APPRAISED.
    I'VE BEEN WONDERING IF THERE IS ANY OTHER MEANS OF BUYING SUCH A PRECIOUS TOOL FROM YOUR STORE RATHER THAN BUYING IT DIRECTLY FROM EBAY AS I'M NOT REALLY ACQUAINTED WITH THE ONLINE BUSINESS!..
    THANKS AGAIN FOR TAKING YOUR TIME,
    BE BLESSED!
