They are identical on an firmware and a hardware stuffing. :) --- Quote from: precaud on September 22, 2018, 12:12:45 pm ---Yes, I always discharge capacitors before testing. But I wasn't testing capacitors last time it was used - I was sorting thru a box of pulled transistors, separating FETs from BPs. It's quicker than looking up the numbers :) So this failure is unexpected. --- End quote --- I don't find any serious obstacles not to manage to repair this device. The scheme is rather simple in understanding if to study a detailed manual from dear Karl-Heinz. :) --- End quote --- Thanx I`m looking for version with BIG monochrome display for my old eyes Any ideas? |

I have also weak eyes therefore I have here such clone with the big monochrome blue display! https://ru.aliexpress.com/item/Free-Shipping-New-12864-LCD-Transistor-Tester-Capacitance-ESR-Meter-Diode-Triode-MOS-NPN-LCR/2044590569.html? spm=a2g0s.9042311.0.0.274233edI9VCwo But he has no case. :D |

I was fairly happy with it up till then. Probably not worth trying to repair... sigh. --- End quote --- My piece failed not long after I got it, but I was testing some uncharged cap . After putting a new chip, so far it has been lasting quite a while. I am suspect the original chip might be 2nd rated part. I don't and can't fault them at such a low price they are selling. |
| precaud:
Interesting. I wonder if there's a difference between DIP and flat pack packages in this respect? |

How does one do a FW update? Is there a pinout for J6 somewhere? I can think of lots of features to add such as Vbe at Vce_sat. |
