electro - types of meter

• Electrical Measurements


  Quantify various electrical parameters such as voltage, current, resistance, etc. through measuring instruments

  
• Meters


  • Means by which the invisible action of electrons can be detected and measured
  • Necessary in examining the operation of a circuit
  • Terminals are provided to connect it to the circuit
  • The polarity of the terminals must be observed for proper connection
  • A red terminal is positive and a black terminal is negative
• Analog Meters


  A type of measuring device that shows information using a moving needle or pointer on a scale

  
• Digital Meter


  A device used to measure various electrical quantities, such as current, voltage, resistance, and frequency, in a digital format

  
• Digital Meters


  • Often more accurate and precise than analog meters
  • May offer additional features such as data logging, connectivity options, and the ability to measure multiple parameters simultaneously
  • Commonly used in industrial, commercial, and residential settings for various electrical measurements and applications

  
• Digital Meters

  • Digital Multimeter (DMM)
  • Clamp Meter
  • Digital Power Meter
  • Digital Energy Meter
  • Digital Frequency Meter

  
• Using an Ammeter


  1. Select the Ammeter

  2. Connect the Ammeter

  3. Turn on the Power

  4. Read the Measurement

  5. Turn off the Power and Disconnect

  
• Setting up an Ohmmeter

  1. Make sure your meter has a battery installed or is plugged in

  2. Plug your test leads into the sockets on your meter

  3. Touch the 2 ends of the leads together to make sure the meter is zeroed

  4. Test your ohmmeter on a store-bought resistor, if you can

  
• Measuring Resistance with an Ohmmeter

  1. Disconnect all power to the circuit you're testing

  2. Set your ohmmeter to the appropriate scale, if possible

  3. Touch the 2 probes to oppose ends of the circuit

  4. Read the number on your ohmmeter to find the circuit's resistance

  5. Isolate the components of an electrical circuit to test them individually

  6. Turn the ohmmeter off when you're done using it

  
• Using a Voltmeter


  1. Select Voltage Range

  2. Connect Probes

  3. Read Display

  4. Interpret Reading

  5. Disconnect Safely

  
• Polarity is important when using a voltmeter. The negative terminal of the voltmeter must be connected to the more negative point in the circuit, and the positive terminal to the more positive point in the circuit.
• Always follow safety precautions, especially with high voltages, and consult manuals for specific voltmeter instructions.
