Stingrays. Stingrays are a family of cartilaginous fish containing nine genera and about 70 species. They can be found in all tropical and sub-tropical seas, and there is also a freshwater-only sub-family-the river rays.

This tutorial will show you how to use a digital multimeter (DMM), an indispensable tool that you can use to diagnose circuits, learn about other peopleâs electronic designs, and even test a battery. Hence the âmultiâ-âmeterâ (multiple measurement) name.ou have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if youâve measuring a 12V battery, use the 20V setting.
