TC1 lcr-meter transistor-tester fix

That means the tester measures those voltages between the probe pins and assumes an external voltage source. Typically this is caused by a bad SRV05-4 or by damaged MCU pins. Remove the SRV05-4 and check again.

I have a blue version. U5 gets very hot after just 1 test.
indman:
Cartel,remove D1 and D2 from the PCB and turn on the tester without these parts. If nothing changes, the main controller is damaged.
All of these nuances are chewed up in detail in this thread several times on every page.

Hi to all,
first of all let me say THANKS to all of you for this amazing thread, I've learned a lot from reading.
I'm owner of a TC-V2.12k. Mine worked fine until I forgot to charge the battery for... years |O. Now I replaced the dead battery with a new LP524558 3.7V 1450mAh battery. After full charge (red led, than green) pressing the start button the device boots, the screen turns on but I see only the message "Charge the battery" with a (wrong) [ Vbat = 2.26V ] message. No way to calibrate, only that message.
Now the question: is there a way to "reset" the device or to "force" a new calibration?
Thanks for your time.
Bob

Hi, have you measured the voltage of the replacement battery, is the device really fully charged?
Can you use it while charging?
