Multimeter Symbols Explained: A Field Guide to Every Dial Position

Q: What does the continuity symbol ())) on a multimeter mean?

The continuity symbol (often shown as ))) ) beeps when the circuit is closed, so you can trace wires and check a circuit is intact without reading numbers. It is the fastest way to find an open or shorted path.

Q: Do CHINYOO multimeters include a temperature symbol?

Some models do. The DT700C pocket multimeter, for example, measures temperature from −20 °C to 1000 °C with a thermocouple probe, shown on the dial with the °C position. Check the specifications of each model for the functions it offers.

The dial on a digital multimeter is the most intimidating part for new technicians — yet once you can read the symbols, every function is obvious. Here is the reference list we hand to every new engineer on our production floor.

Voltage and Current Symbols

V⎓ — DC voltage
V~ — AC voltage
mV — millivolts, for low-voltage signals and sensor work
A, mA, μA — current ranges; always move the lead to the correct jack first

Resistance, Continuity and More

Ω — resistance
))) — continuity; beeps when the circuit is closed
→|— — diode test
F, -|(|- — capacitance
Hz — frequency
°C / °F — temperature, on meters with a probe input

Non-Contact and Auto Features

NCV (non-contact voltage) detects live voltage through insulation without touching conductors — the fastest way to confirm a circuit is live. AUTO or auto-ranging means the meter selects the right range for you, which is why our 6000-count auto-ranging series is a favorite among maintenance teams.

How to Read the Display

The display shows three pieces of information: the value, the unit, and the range you are in. A 6000-count meter reads up to 5999 on each range — at the 600 V range it can show a full 599.9 V with one decimal place. Backlight and data hold keep that reading readable and locked in dark, awkward positions.

If You Learn One Habit

Always check the two symbols together: the function and the range. Moving the test leads before selecting the range is the cause of most blown fuses and damaged meters. Pair your multimeter with a voltage tester for a quick go/no-go check, and reserve the meter for the precise measurements.

FAQs

What does the V~ symbol on a multimeter mean?

V~ is AC voltage and V⎓ is DC voltage. Set the dial to the matching symbol for the signal you are measuring — most meters also have a mV position for low-voltage sensor work. Always move the test lead to the correct jack first.

What does the continuity symbol ())) on a multimeter mean?

The continuity symbol (often shown as ))) ) beeps when the circuit is closed, so you can trace wires and check a circuit is intact without reading numbers. It is the fastest way to find an open or shorted path.

Why does my multimeter show 1 on the left side of the display?

A "1" on the left is the overload / out-of-range indicator. It means the reading exceeds the current range — switch to a higher range, or with autoranging meters select the function again. In resistance mode it usually means an open circuit.

Do CHINYOO multimeters include a temperature symbol?

Some models do. The DT700C pocket multimeter, for example, measures temperature from −20 °C to 1000 °C with a thermocouple probe, shown on the dial with the °C position. Check the specifications of each model for the functions it offers.
