Description Of The Multimeter

What is a multimeter?

Before we know how to use a multimeter,we must understand a safety information about multimeter.

To avoid possible electric shock or personal injury,PLEASE follow these guideline

  • Do not use the meter  or test lead if they appear damage or not operating properly.
  • Always use proper terminal,switch position and range for measurements.
  • Verify the meter`s operation by measuring a known voltage.
  • Do not apply more than the rated voltage,between terminals or any terminal and earth ground.
  • Use caution with voltage above 30 VAC rms,42 VAC peak or 60 VDC.It pose a shock hazard.
  • Disconnect circuit power supply and discharge all high-voltage capacitor before testing RESISTANCE,CONTINUITY,DIODE OR CAPACITANCE.
  • Do not use the meter around explosive gas and vapor
  • When using test lead,keep your finger behind the finger guard.
  • Avoid working alone
  • Use only the replacement fuse specified.
  • Check the test lead  for continuity before use.Do not use if the reading are high or noisy.

FUNCTION OF MULTIMETER COMPONENTS

1) Terminal

(1) INPUT TERMINAL FOR MEASURING AC AND DC CURRENT TO 10 AMPERE

(2) COMMON (return) TERMINAL FOR ALL MEASUREMENTS

(3) INPUT TERMINAL FOR MEASURING VOLTAGE,CONTINUITY,RESISTANCE,

CAPACITANCE,FREQUENCY AND DIODE

2) Power up option

(1) TURN ON ALL DISPLAY SEGMENTS

(2) DISABLE BEEPER. bEEP icon IS DISPLAYED WHEN ENABLE

(3) ENABLE LOW IMPEDANCE  CAPACITANCE MEASUREMENT . LCAP icon IS DISPLAYED WHEN ENABLED

(4) DISABLES AUTOMATIC POWER-DOWN (sleep mode). PoFF icon IS DISPLAYED WHEN ENABLED

3) Measurements Selector

(1) AC VOLTS true rms ( 600.0 vac ) & FREQUENCY (Hz) ( 0 Hz -50 kHz )

(2) DC VOLTS ( 600.0 vdc )

(3) AC & DC MILLIVOLTS ( 600 .0mV )

(4) OHMS ( 40.00 MΩ )

(5) CONTINUITY ( 600 Ω )

(6) DIODE TEST ( 2.000 V ) & CAPACITANCE ( 1000 nf )

(7) AC CURRENT ( 10 AMPERE ) & FREQUENCY ( Hz )

(8) DC CURRENT ( 10 AMPERE )

    thank you, this website helped me pass my project.. :)

  2. Great article you have written – very easy to understand :)

  3. Thanks for the tips, it’s a pretty good write up for people that need some help with multimeters.

    What do you think about Fluke multimeters?
