Still I have an impression I often need to grip and press firmly to get a reasonable readout. Is this normal?
Obviously the readouts for low resistance components are not super precise and I can obtain much more stable and precise values with dedicated milliohm or battery meters. But it is absolutely enough for checking the components on the PCBs.
Couple of suggestions/questions:
1. Can you detect open-loop OL. At the moment the unit never detects it, but rather show random high +-2-3GOhm values, I assume this is just some kind of noise being amplified. Can you detect this and show OL instead if the variance of the measurement is too high for anything that makes sense?
2. Can you make press and hold instant (without countdown) turn off? (Similar to how you turn on the device) At the moment in v1.4.4 in my unit it does nothing except beeping. I'd love to have a quick way to turn it off. Of course like you said in the previous posts the timeout should work okay and I should not worry about the battery life etc. But I just have a habit and I like turning off things myself ![Roll Eyes ::)](https://www.eevblog.com/forum/Smileys/default/rolleyes.gif)
3. Can you make the unit beep once when it is turned off, both manually and with timeout?
Btw. Is IdealTek ST-5 some kind of rebranded ST42? It really looks almost the same, except the UI layout being slightly different and price noticeably higher. ![Huh? ???](https://www.eevblog.com/forum/Smileys/default/huh.gif)
This thread hasn't been updated in a while, and we are late.
we are still here, and we haven't run away

Thanks for the information so we can make it better.
“Still I have an impression I often need to grip and press firmly to get a reasonable readout. Is this normal?”
1. It is often necessary to use some force to get the correct result during use. The reason is that the tip of the tweezers is gold-plated in order to keep the surface in good contact, but the pins of the components to be tested or the surface of the solder are prone to insulating flux and oxide layers, so if the results do not meet expectations, try to use some force, so I always Opt for extra pointed multimeter leads, even if they tend to break frequently.
“for low resistance components are not super precise”
2. For the measurement of milliohm impedance, we have not stopped thinking about these problems. A few days ago, we tried to use the tip of the tweezers for four-wire measurement. The user experience is not as good as precise tweezers, but the test results are full of imagination. Image attached.
“Couple of suggestions/questions:”
1. Open-loop OL detection, this suggestion is very good. Compared with it jumping around randomly, an over-range prompt will make people feel more at ease.
2. We have received many requests for a long-press shutdown. There will be an update of the code version recently. This function will definitely be launched. After the new version is released, I will tell you in the forum.
3. There is no problem with the implementation of the shutdown prompt sound, we will try to add one. It is true that when we are busy with other things, it often shuts down automatically with only screen prompts, which is not so comfortable.
“looks almost the same”
It looks similar to ST-5 in appearance, but they are entirely different. In terms of structural design, ST42 will be much more stable. This is a user experience that other tweezers cannot provide. Of course, these experiences cannot be seen directly.
Now almost all mobile phones in the world are like iPhones, but an iPhone is an iPhone.
We are also trying to make an elegant product from the inside out
