Just landed on my desk today is a Power-Z KM001 USB meter. I have a few different devices like this and was attracted to something with more capabilities and PC connectivity.
So far however, even after reading the user manual, and UnionRepair’s how to use guide, I find it is not behaving in a simple way, and not like the instructions.
Take the most basic requirement beyond simple voltage/current measurements; to measure Wh.
I would expect to select a channel, plug it in and off it goes. Once finished, a simple press-and-hold to clear the counter back to 0 and off we go again. - Well, not so far.
I have only reset it by going in a doing a factory reset of the whole device.
Does anyone know of a review or other webpage with ‘good’ instructions that you can actually follow? (the UnionRepair’s how to use guide is the user manual on a web page, so not any help)
If not, perhaps we can start to build one here.
I’ll keep fiddling with it to see if I can get anywhere by trial and error.
