What is the symbol for continuity?
diode symbolContinuity: Usually denoted by a wave or diode symbol. This simply tests whether or not a circuit is complete by sending a very small amount of current through the circuit and seeing if it makes it out the other end. If not, then there's something along the circuit that's causing a problem—find it!

What are the Different Symbols of a Digital Multimeter?
The following is an explanation of the most typical multimeter symbols. The different symbols are the following:
Final Thoughts
Just like other tools, multimeters have electrical symbols as well. Their means are essential for proper use and understanding of the product. No matter if you are still learning to use the device or you have one for a while already, breaking uncertainties on what a couple of the symbols mean must be given attention.
Digital multimeter dial
This is a composite image and not an actual dial. It shows a variety of functions found on multiple Fluke digital multimeter dials. No single model contains all these functions. On many models, some function icons are displayed in yellow. This indicates the digital multimeter’s yellow function button must be pressed to select those measurements.
Digital multimeter buttons
This is a composite image. Actual assortment and variety of buttons may vary by digital multimeter model.
Digital multimeter jacks
Not all meters off an input jack for milliamps (mA) and microamps (μA).
1. DC Voltage
DC stands for direct current. DC voltage will allow you to measure the voltage of direct current electronics. This includes most small electrical circuits such as batteries and indicator lights. You’ll also use DC voltage when working on a vehicle.
2. AC Voltage
This is the setting you’ll use most when working on electrical circuits that are hooked to the grid. In the US, you’ll mostly be measuring AC voltage between 110V and 240V.
3. Millivolts
Millivolts measure fractions of a volt. If you’re dealing with low-voltage circuits, you’ll probably use the millivolts reading rather than the standard voltage selection.
4. Amperes
Called amps for short, amperes measure electrical current. You can think of the current as the total amount of electricity moving through a circuit.
5. Milliamps
A milliamp is 1/1000 of a standard amp. When you’re measuring a low-current electrical circuit, you’ll want to switch from amps to milliamps to get an accurate reading.
6. Microamps
Microamps are even smaller than milliamps. While a milliamp is one-thousandth of an amp, a microamp is one-millionth of an amp and it’s used for measuring the lowest current circuits.
7. Ohms
Resistance is a measurement of how much opposition a circuit or object puts up against the flow of electricity, and it’s reported in ohms. Materials with high resistance restrict electrons from flowing, while items with low resistance allow the electrons to flow freely. Conductors like metal have low resistance.
