AKtech DB32 LED Meter Adjustments

AKTECH DB32 LED Meter Instructions.
I purchased a few of these meters as a quick and easy way to monitor a balanced audio mixer output. The video came about because NONE off the vendors of these things actually use an English SPEAKING human to write the adjustment instructions. I have access to person who could translate the Chinese for me but none of the vendors would send the instructions in Chinese unless I made a purchase. SO.... After a lot of poking around the net and more experimenting, I came up with what you see here. I will post another video that shows the way the meter was connected. Till then, questions? Email [e-mail] and I will try to answer.

NO clue... I BOUGHT them from an Ebay vendor. They are nice to watch but impossible to calibrate.
