A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits. This instrument will let you check to see if there is voltage present on a circuit.
Where can I get copy explaining what the symbols mean on a sperry multimeter and how to use them. Regards Frank
To determine if a capacitor is defective, use an Ohmmeter of a Multimeter.
A Multimeter is an electronic instrument, every electronic technician and engineer’s widely used piece of test equipment. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. There are two types of multimeters: Analog Multimeter: The Analog Multimeter or VOM (Volt-Ohm-Milliammeter) is constructed using a moving coil meter and a pointer to indicate the reading on the scale. Digital Multimeter: We mostly used a multimeter is a digital multimeter (DMM). The DMM performs all functions from AC to DC other than analog. It has two probes positive and negative indicated with black and red color as shown in the figure. there are some best multimeters for HVAC.
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,

In Digital multimeter we use 9V Dc battery.

Because your multimeter is not an adequate device for this kind of measurement. Use the correct multimeter to display the triangular wave value.
To check the frequency of an electrical signal using a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter probes to the signal source, ensuring proper polarity. The multimeter will display the frequency in hertz (Hz) on the screen.
Use for multipurpose
Voltmeter or multimeter.
Use a multimeter set to continuity position and touch one probe from your multimeter to each conductor. If you hear a tone from the multimeter then your fuse is good.
To use a multimeter effectively for measuring electrical parameters, first select the appropriate setting for the parameter you want to measure (voltage, current, resistance). Next, connect the multimeter leads to the circuit or component being measured. Ensure the multimeter is set to the correct range and polarity. Finally, read the measurement displayed on the multimeter screen and record the value if needed.
They are called test leads, you would use them to connect the multimeter to the points that are to be tested.
To test an LED light using a multimeter, set the multimeter to the diode testing mode. Connect the positive lead of the multimeter to the anode of the LED and the negative lead to the cathode. If the LED is working, the multimeter will display a voltage drop. If there is no voltage drop, the LED may be faulty.
