51 IN STOCK. 1  Description Description- As electronics get smaller and smaller, you'll need a hand examining PCBs and this little USB microscope is the perfect tool. Its smaller and lighter than a large optical microscope but packs quite a bit of power in its little body.
1 Carry the microscope with one hand grasping the neck and the other supporting the bottom. 2  Always have the shortest, low power objective lens facing the stage when you put a new slide on the stage or remove a slide. Be sure that the low power objective is in position before you remove a slide from the stage and before you put the microscope away. 2  When you unplug the microscope, grasp the plug, not the cord. 3  Microscopes are numbered and should be put away in the niche bearing the same number in the microscope cupboard.
