DIGITAL MULTIMETER A Must Have For Dealing With Electronics
Digital Multimeter Digital Display Manual Range setting dial Probe Connectors
DIGITAL MULTIMETER AC Volts DC Volts Ohms AC Amps
ANALOG METER Permanent magnet Movable coil Core Spring Scale marks Needle
MULTIRANGE ANALOG METER Reading = ________ 3.6
Uses for a Multimeter 1) Determine if a part is damaged or worn out 2) Determine if an unexpected amount of power (too much or too little) is being used. 3) Determine what type of part something is 4) Determine the electrical denomination (value) of a part 5) Manually read sensors and chips to aid designing and debugging
