you claim you are happy to answer questions - and then don't.
Here are the basic questions again...
What is your device adjusted against (i.e. type and its calibration status)?[/li][/list]
How long is the burn-in period?
What is the guaranteed 90 day and 1 year performance? Under what conditions, e.g. shock, temperature, power cycling?[/li][/list]
In response to your concerns:
1) I answered here because the OP posted in the BEGINNERS forum, not the Metrology Volt-Nut forum. Since it is a beginners forum question, your volt-nut concerns probably wouldn't apply to beginners, right?
2) If you view my listing that I linked to, it clearly may be adequate for a beginner but not a volt-nut or Metrology product.
3) Your pattern of posts and replies in various threads indicate that you have a somewhat negative and hyper-critical tone toward what you may consider to be, in your view, less-than-satisfactory participation by certain forum members. Some might categorize you as being arrogant to the degree of trolling for an argument or some such. That's not what most of us are here to engage in.
4) My answers to your re-posted questions that you dredged up from a dead thread are as follows:
Here are the basic questions again...
What is your device adjusted against (i.e. type and its calibration status)?[/li][/list]
A new 2023, factory- calibrated 5-1/2 digit Fluke 8808A bench meter owned by a business acquaintance.
How long is the burn-in period? Less than 30 days.
What is the guaranteed 90 day and 1 year performance? NONE Under what conditions, e.g. shock, temperature, power cycling? Not Applicable.
For $25-$30, no reasonable or serious-minded volt-nut would consider buying one of my devices for the kind of purposes that you are obviously referring to.
So, why do you try to provoke hard feelings or try to encourage misunderstandings as you insinuate that, somehow and repeatedly, I am misrepresenting my devices?
As I said in previous threads, these devices are offered for hobbyists and DIYers and are aimed at limited, low-cost functional checking of DMM's and are not intended to substitute for high-level calibration.
I know from reading some of your replies that you are a capable of contributing valuable and helpful information to this forum so, tell me what I can do differently to help you re-orient yourself to move in that direction?
Major.
