The readings measured by this tester are accurate, and among the important characteristics measured are input resistance Rin, common base and common emitter. This type of transistor tester usually performs three types of tests: Forward current gain, base to collector leakage current with open emitter, and short circuits from collector to base and emitter.Ī Laboratory Standard Tester is used to measure a transistor’s parameters at various operating conditions.
The advantage of using this tester is such that among all the components in the circuit only transistor is not removed. This type of transistor tester specifies to a technician whether a transistor is still operative or dead. Unfortunately, for me it is currently a (fairly expensive) broken board in my test box.Quick check in circuit checker transistor tester is used to check whether a transistor is performing properly in a circuit or not.
#TRANSISTOR TESTER PCB PORTABLE#
The few times it functioned correctly, it seems to be a good portable tester. So, my recommendation is to double-check yours as soon as you get it making sure that the USB connector is secure. Also, since receiving it originally took awhile and I didn't immediately jump on trying to resolve the issue since I believed it was "normal" to draw that much power, I missed the 30-day warrantee window.
#TRANSISTOR TESTER PCB UPDATE#
I'll provide another update if it is eventually resolved. The maker explains that he checks each one before sending and seems to indicate he believes the problem occurred in either shipping or through "mishandling." Communications on getting this resolved has been slow and continues. I have had a string of communications back to the maker in which I was asked to try different cable and different power adapters. I can even hear small popping sounds from the connector area when it is plugged in. Update: The cause of the power use seems to be a short on the USB connector on the board. Interestingly (perhaps strangely) enough it does draw a good amount of power-my Apple shut down the USB port a couple times and I found myself needing to drive it off a wall wart. Optional: 1x USB C Cable (select from the options menu, if you need one)Ī nice addition to my portable electronics test kit. 3x Probe Wires (Wire Hooks not included).1x Component Tester (Keychain Version) // Matte Black PCB.
#TRANSISTOR TESTER PCB GENERATOR#
Capacitors with their ESR values (if any)Īdditionally, a function generator is available at Test Pin 2 (Long Press the test button to open the options menu and select function generator) What comes in the box.
It is able to test the following electronic components. This tiny component tester offers a ☐.5% tolerance which makes it a more reliable and trustworthy testing device. It is small and lightweight so you can carry it around without any hassle. It measures approximately 6cm x 3cm and is a one-button device with a 0.96" OLED Display (128px x 64px). It is based on the popular AVR TransistorTester. It can automatically detect the plugged-in electronic component and measure the desired component parameters without having the user to manually select the component type, unlike the multimeter. Component Tester in a keychain is a universal testing device for electronic components with three or lesser pins.
