MUTLIMETERS Flashcards
it is an electronic measuring instrument used to measure various electrical parameters.

This is where you can see the measurements
Display
Plug-in probes (i.e. to test car batteries)
Ports
Multimeters have two probes. Usually one is black and one is red.
Probes
This tells you what you want to measure.
Selection knob
Placed on the top left corner on most multimeters, this button locks the measurement into place after you’ve taken it.
Hold
It tells you the equipment’s or circuit’s frequency. This is usually placed above the AC voltage option.
Shift: Hertz
The Ohms symbol is an upper case Omega letter. This is used to find the resistance reading.
Ohms
This has a right arrow with a plus sign next to it. As you could have guessed, this tells you if you’re working with good or baddiodes.
Diode Test
This symbol has a V and three hyphens above it and one straight line above it.
DC Voltage
The AC voltage symbol looks like an A with “a road” placed on top of it. It has an A with three dashes and a straight line above it.
AC Voltage
This is the needle-shaped rod that moves over the scale of a meter.

A Needle or Pointer
An Adjustment Screw

Parts of multi tester
This is how you read the value being measured.
Scale
Also known as thedialorinfinity knob. This allows you to adjust the pointer to the zero position of the scale – usually with the help of a flat head screwdriver
Adjustment Screw
It is used to calibrate the multitester when you want to measure the resistance of an object.
Zero-Ohm Adjustment Knob
Also known as aselector switch. This allows you to adjust the settings of the multitester
Range Selector Knob
The holes at the front of the multitester are known as
Ports
is an instrument used to connect a multitester to a Device Under Test (DUT).
