ciccio:
I've received the AN8002 I've ordered some weeks ago, to pair with my AN8008.
Nice instrument, but:
It seems the manufacturer is having some problems with the front panel artwork (see attache photo):
The second switch position is labeled V (DC in white), Vac, Hz and % duty cycle (yellow), but pushing the SEL (yellow) button switches only between V dc and V ac.
To measure Hz and % duty cycle you must rotate the switch to the fifth position, again labeled Hz and %.
The funny thing is that the photos on the supplier's site (Banggood) and other sites show a correct panel.
I'll solve the problem with a little piece of masking tape...
I remember another post reporting the same problem, but I could not retrieve it.
A quick test showed that the meter worked as specified. I like it very much.
Another problem (but my big, heavy and more expensive Meterman 33XR has the same) is that a broken thermocouple will show ambient (or cold junction) temperarure, and not an overrange, as any industrial thermometer will do. A simple pull-up resistor could do the trick.

Mark Hennessy:
Mine is the opposite - the artwork doesn't include Hz and % on the voltage position, but the yellow button does. Ideally, you and I should swap cases :)

I've heard reports of meters where the yellow button only toggles between DC and AC, but yours is the first AN8002 I've seen with Hz and % printing on the case.

From what I can tell, there's no way to predict which version you'll get. There's pros and cons of each - at least it's quicker to switch between AC and DC for you.

ciccio:
In effect I do not pressed hard fo use the meter (it was bpught just for curiosity).
Before I'll decide to use masking tape, please PM me to organize the excange of the cases.
UK and Italian postages will be very cheap.
Best regards

Mark Hennessy:
I was joking about the cases - given how cheap these meters are, it's hardly worth the effort of posting parts of them around :)

Thanks again for posting your pictures. It's interesting to see how these meters are evolving over time :-+

stj:
maybe the differences are controlled by the eeprom - the documentation on the eeprom content is not exactly complete.
