"nktech nk-51h" - proper way of installing battery/fast look inside
« on: January 04, 2018, 02:49:18 pm »
Hi.
I've purchased this meter on ebay for... $1. And it just arrived! Unbelievable (no matter how cr***y this toy will happen to be). But I have one problem: what is the proper way of installing battery? Meter has two contacts (like for AA/AAA batteries, but 9V battery has to be installed) and no single mark of polarity...
Anyone has experiences with this unit?

There is an opening that shows the pcb and there is a "-" sign in the solder mask that is the negative side.  :-//

Thank You for help.
I've opened this meter and made several photos.
The "-" sign on PCB is not the marking for negative terminal, but anyway - it works.
Big fuses I see :)
