With today's auto-ranging meters, you might well ask why. Today meters do that for you, and you might see it happening on some of them.
In older meters, analog types in particular, you had to start with a higher range to be sure you didn't peg the meter measuring say, 220 volts when on the 10 volt scale. Lots of meters where toasted this way, their needles bent, or fuses blown by overcurrent. On higher ranges, the meter would deflect slightly, indicating there was voltage there, but not enough to get a accurate reading. So you scale down until hopefully you get a reading somewhere in mid scale, where the most accurate reading can be made.
So the use was to protect the meter from damage, and provide the most accurate reading possible from an analog meter.
What else can I help you with?
Why does the multimeter show the RMS value of sine wave but not for the triangular wave?
Because your multimeter is not an adequate device for this kind of measurement. Use the correct multimeter to display the triangular wave value.
What means OL in the multimeter?
In a multimeter, "OL" stands for "Over Limit" or "Open Loop." It indicates that the measurement exceeds the range of the multimeter, such as when measuring resistance in an open circuit or when the voltage is too high for the selected range. Essentially, it signifies that the reading is outside the device's capability to measure accurately. If you see "OL," it's advisable to adjust the multimeter settings accordingly.
Can a DT830 digital multimeter measure voltage on an electric fence?
Yes, a DT830 digital multimeter can measure voltage on an electric fence, provided the voltage is within the multimeter's range. However, keep in mind that electric fences often use pulsed DC voltage, which may not be accurately displayed by the multimeter if it is not designed to measure pulsed signals. Additionally, safety precautions should be taken when working with electric fences to avoid electric shock. Always ensure the multimeter is set to the correct voltage setting before measurement.
How do you turn on a multimeter?
To turn on a multimeter, locate the power button, which is usually labeled "Power" or "On." Press this button to activate the device. If your multimeter does not have a power button, it may turn on automatically when you select a measurement mode or connect test leads. Ensure that the multimeter is set to the appropriate function for the measurement you intend to take.
How do you check the voltage going to the coil?
To check the voltage going to the coil, use a multimeter set to the appropriate voltage range. Connect the positive lead of the multimeter to the terminal of the coil and the negative lead to a good ground point. With the ignition turned on (or while the engine is running), read the voltage displayed on the multimeter. Ensure the voltage is within the specified range for proper coil operation.
How to measure voltage accurately in an electrical circuit?
To measure voltage accurately in an electrical circuit, use a digital multimeter set to the voltage measurement range. Connect the multimeter's probes across the component or points where you want to measure the voltage. Read the displayed voltage value on the multimeter's screen. Make sure to select the appropriate voltage range on the multimeter to get an accurate measurement.
How to measure volts accurately in an electrical circuit?
To measure volts accurately in an electrical circuit, use a digital multimeter set to the voltage range needed. Connect the multimeter probes to the circuit's positive and negative terminals. Read the voltage displayed on the multimeter screen for an accurate measurement.
How to use a multimeter effectively for measuring electrical parameters?
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.
How to use a multi meter effectively for measuring electrical parameters?
To effectively use a multimeter for measuring electrical parameters, follow these steps: Set the multimeter to the appropriate function (voltage, current, resistance). Connect the probes to the circuit being measured. Take the reading displayed on the multimeter. Ensure the range is suitable for the measurement being taken. Be cautious of electrical hazards and follow safety precautions. Record and interpret the measurement accurately.
How can I measure voltage accurately in an electrical circuit?
To measure voltage accurately in an electrical circuit, use a digital multimeter set to the voltage range of the circuit. Connect the multimeter's probes across the component or points where you want to measure the voltage. Read the displayed voltage value on the multimeter's screen for an accurate measurement.
How can a multimeter be used to test voltage accurately?
A multimeter can be used to test voltage accurately by selecting the appropriate voltage range on the device, ensuring the probes are connected to the correct terminals, and reading the voltage measurement displayed on the multimeter's screen.
Why does the multimeter show the RMS value of sine wave but not for the triangular wave?
Because your multimeter is not an adequate device for this kind of measurement. Use the correct multimeter to display the triangular wave value.
How to use a multimeter to check voltage accurately?
To check voltage accurately using a multimeter, set the dial to the voltage range you expect, connect the red probe to the positive terminal and the black probe to the negative terminal, and read the display for the voltage measurement. Make sure to select the appropriate range and follow safety precautions.

How can I check the resistance in a wire?
To check the resistance in a wire, you can use a multimeter. Set the multimeter to the resistance (ohms) setting, then touch the probes to each end of the wire. The multimeter will display the resistance measurement in ohms.
Who has a wide range digital or analog multimeter?
The analog multimeter has a wider range.
How can I use a multimeter to check the frequency in hertz (Hz) of an electrical signal?
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.
