  2. ELECTRICAL MULTIMETER TEST INSTRUMENTS

  3. ANALOG METER DIGITAL METER VOMMULTIMETERS MEASURE RESISTANCE – VOLTAGE - CURRENT

  4. To Measure VOLTAGE • Set the Leads • Position the Selector • Set the Range • ALWAYS MEASURE VOLTAGE ACROSS THE LOAD or the SOURCE! VOLTAGE MEASUREMENT

  5. To Measure VOLTAGE • Set the Leads • Position the Selector • Set the Range • ALWAYS MEASURE VOLTAGE ACROSS THE LOAD or the SOURCE!

  6. To Measure RESISTANCE • Set the Leads • Position the Selector • Set the Range • ALWAYS MEASURE RESISTANCE ACROSS THE LOAD DISCONNECTED FROM THE POWER SOURCE! RESISTANCE MEASUREMENT

  7. ALWAYS MEASURE RESISTANCE ACROSS THE LOAD DISCONNECTED FROM THE POWER SOURCE!

  8. To Measure CURRENT • Set the Leads • Position the Selector • Set the Range • MEASURE CURRENT • IN SERIES WITH THE LOAD CONNECTED TO THE POWER SOURCE! CURRENT MEASUREMENT

  9. ALWAYS MEASURE CURRENT IN SERIES WITH THE LOAD CONNECTED TO THE POWER SOURCE!
