In both of these precautions you do not want to jar the needle from it jeweled pivot. A typical multimeter can measure voltage current and resistance. Do not place your multimeter in a place where you may accidentally knock it over or pull it to the floor.

The meter in series with the circuit andor component.
This is not a Auto-ranging Digital.
Function switch at a high level and decrease to a lower level. It is still a good idea to try to read the value about mid scale or mid range on the meter. This is the circuit without the meter. Analog Multimeter Measuring Current.

SIK BINDER 39 Parts of a Multimeter Display. Where values are displayed. Used to select what is being measured and the upper limit of how much is being measured.
Where the positive port connector is plugged in if you are measuring less than 100mA of current.
A multimeter is has three parts. Display Selection Knob Ports The display usually has four digits and the ability to display a negative sign. A few multimeters have illuminated displays for better viewing in low light situations. The selection knob allows the user to set the multimeter to read different things such as milliamps.
There are two types of multimeters.
Analog multimeter VOM and digital multimeter DMM. VOM has more than one scale printed on the face of the meter. The VOM multimeter has four functions. DCV ACV W and DCMA as indicated by the four circular brackets around the large selector switch in the Iower center of the meter.
PECEP 1 LAB Activity 3 Understanding Analog and Digital Multimeters Directions.
Research for analog and digital multimeters 2. Attached sample picture of an analog and digital multimeter. Using the pictures provided identify and label the parts of the instrument. Analog multimeters are cheaper than digital multimeters but not as robust or simple to use.
Analog multimeters are preferred by some technicians because the movement of the needle can show you some things that are not so obvious with digital multimeters.
PARTS OF THE ANALOG MULTITESTER. Pointer or Needle indicates the values read from the scale. Multimeter is a measuring instrument. It can be used to measure voltage current and resistance.
An analog meter Figure a moves a needle along a scale.
The function of the meter can be changed by switching the dial. Analog multimeter shown in the figure is cheap but difficult for beginners to read accurately. Most modern multimeters are digital. Ive seen hundreds of analog multimeters but I have never yet seen one that measured either transistor gain or capacitance.
Better keep the meter you have for those functions.
I tried to find some info on the Protek A-423. Hmmm Meter movements rarely fail so that should not be a concern. The meter reading on the power supply should not be used as accuracy is not insured. Use a calibrated DMM to measure voltage such as the Fluke 45 Multimeter.
Current limit may be used to limit the current to a maximum amount.
Always turn off the power supply before connecting a circuit. View and Download Craftsman 82362 owners manual online. 82362 multimeter pdf manual download. An analog multimeter is a meter that can measure two or more electrical properties and display the measured properties along calibrated scales using a pointer.
Analog multimeter uses an electromechanical component called a DArsonval movement to move the pointer along the scales to display measured values when the test leads are connected to a circuit device or circuit component.
Never use meter if the meter or test leads are damaged or broken. Make sure that the test leads are not cut or otherwise damaged. Never apply an input signals exceeding the maximum rating input value. 2Be sure to disconnect the test pins from the circuit when changing the function.
Analog Multimeter Parts And Their Functions For electricians the electrical technician must have understood correctly about the parts in the multimeter tool.
However for beginners who are not yet familiar with the multimeter component little will be explained about the parts of the multimeter that are mandatory to know. The pointer or needle- use to point or read the measurement using the meter scale base of the range and settings you prepared during the test of a device or line of a voltage. Meter scales- this is the basis of the measurement where the graduation bar drawn in the body commonly the resistance or ohms scale have a measurement from 0-2k ohms depend of the range and settings. Switched range analog multimeters are very cheap but are difficult for beginners to read accurately especially on resistance scales.
Each type of meter has its advantages.
Used as a voltmeter a digital meter is usually better because its resistance is much higher 1 M or 10 M compared to 200 for a analog multimeter on a similar range. Multimeter and plug the black probe into COM common jack and the red probe into mAV Ω. Set the multimeter to 2V in the DC range DC is a straight line AC is the wavy line. Squeeze the probes with a little pressure against the positive and negative terminals of the AA battery.
The black probe is customarily connected to ground or -.
A multimeter or a multitester also known as a VOM volt-ohm-milliammeter is an electronic measuring instrument that combines several measurement functions in one unit.
