Shannon ST42 LCR Tweezer Test and Comparison Thread
dazz1:
My Shannon tweezers refuse to beep, no matter what I say to them.
I have even resorted to reading the instruction card.
The sound level is 4 and ON.
Hold is ON.
I updated to the latest firmware.
We seem to be suffering a communications breakdown, and I don't know what to do.
Should I seek professional help? Maybe a relationship counseling service?
Sorama:
I have the same issue.
I even can’t get official confirmation if nor when the tweezers should beep.
So I am going to order those Zoyi tweezers and forget about the Shannon tweezers, although they did not come cheap.

This sounds rather extreme. From what I've seen and read, the Shannon tweezers are far better in terms of measurement capability. But if your needs are simple, maybe the others will suit you better. You should be able to sell your ST42 for more than the Zoyi cost.
I've never considered the tweezers as something for doing continuity testing, as generally I want to compare continuity between one point and many others across the PCB - so separate probes are better.
But by all means they are great for doing comparison of low ohms (short) measurements across multiple parallel components to try identify which is faulty.
In terms of beeping, the only sound I've ever noticed from my ST42 is a small chirp sound. Not really a beep.
You should hear the chirp (if sound enabled) on every press or movement of the joystick. For someone with hearing problems, it may not be audible.
Sorama:
Mine does chirp when booting, but not when using the button.
So I presume mine is a DOA.
I’m aware of the quality of these tweezers, but any device you use for finding shorts (in a component) or continuity in general, should beep.
Like you said, that is a main functionality of the tweezers.

To beep or not to beep wasn't a factor in my decision to buy Shannon tweezers. I never expected they could, would or should beep. It is entirely possible they are beeping, but I can't hear them.
