Well, the meter survived quite well the torture - thanks for doing this.
For a UNI-T product, overall, I couldn't agree more but not when compared with the better brands I have looked at.
Then again, having the meter modified may have saved it from the total destruction we are use to seeing with this brand. It's not good enough for me to want to invest more time into looking at the brand again. After 13 products, I think we have learned our lesson.
A few unknowns, especially due to the dramatic self-healing, but that happened with the other meters as well.
Well, let's be clear. If we are talking about the contacts opening up (>1kohm) some meters have self healed.
Cycle3 shows the five worse meters I have looked at. All of these went open before 7000 cycles. It's good to see Keysight in the mix with UNI-T and the free HF meter.
But consider the other five meters in
Cycle4. None of these meters ever opened up during the entire duration of the test. Note that even Dave's 121GW with it's cobbled switch and countless contacts hung in there. While Dave's test limited the measurement to 10 ohms, I like being able to see the higher values and trusting the HP bench meter.
After 50k the status of its contacts and PCB are quite interesting. No way to compare with the 17B+, but still...
True but again, the wiper contacts were not locked to the knob. How would the meter have held up had the pins not broke? What if they hadn't spec'ed the frequency counter to 200MHz and the meter still had the original components? Would a small ESE event have damaged it?
