THIS COMES AS PICTURED. IT DOES POWER ON AND THE METER NEEDLE MOVES. I HAVE TESTED A COUPLE CALIBRATION TUBES AND WHAT I FOUND IS THAT THE SOCKETS NEED USED AND MAYBE DE-OX. THIS HAS BEEN SITTING A LONG TIME AND THEY ARE VERY TOUCHY AND PROBABLY A LITTLE OXIDATION ON THE TERMINALS. THIS USUALLY WORKS ITS WAY OUT AFTER SOME USE OR YOU CAN USE SOME DE-OX. WHEN DOING A TEST THE SHORT LITE SEEMS TO REMAIN ON AND THE METER PEGS TO MAX ON A KNOWN GOOD TUBE. MY GUESS IS THE CAP AND MAYBE THE RESISTOR PICTURED NEED REPLACED AND CALIBRATED. YOU MIGHT BE ABLE TO ADJUST THE METER NEEDLE BUT A PROPER CALIBRATION SHOULD BE PERFORMED ON IT. THERE IS REALLY NOT MUCH TO THESE SIMPLE TESTERS SO AS LONG AS THEY POWER ON THE REST IS PRETTY SIMPLE TO FIX OR ADJUST. SOMEONE HAS ALSO PUT SOMETHING HOT ON THE METER COVER. JUST COSMETIC AND WILL NOT AFFECT THE PERFORMANCE. THIS IS SOLD AS IS. SHIPPING SHOWN IS FEDEX OR UPS GROUND TO THE LOWER 48 STATES. ALL OTHERS TO USE EBAY GLOBAL. THANKS!
