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. A flattened body shape and disc-shaped pectoral fins help stingrays live and hide in sand and mud underwater. The famous barbed stinger on the tail is only used in self-defence, often when they are stepped on in shallow waters.
Split and merge into it. Answer by Freezinweasle. Confidence votes 7.9K. A multimeter is used for measuring electricity and because it has many different functions, it has been named a multimeter. They generally measure AC and DC voltage, amps, and resistance (ohms).
Set the multimeter to Ohms or Resistance. Turn the meter on if it has a separate power switch. When multimeter measures resistance in ohms, it can not measure continuity because resistance and continuity are opposites. To do this, insert the black probe into the COM or - jack and insert the red probe into the A jack. 2  Shut off power to the circuit. 3  Open the portion of the circuit that is to be tested (one lead or the other of the resistor). 4  Insert the meter in series with the circuit such that it completes the circuit.
