1. Provide an overview 2. Information about safety The digital multimeter is created and manufactured in the United States. On the basis of EN61010-1 safety regulations, a warning has been issued. When utilizing an electronic measuring instrument or a hand-held digital meter, extra care should be used because inappropriate use can damage the electric multipurpose meter.

Remove test leads before changing the battery or fuse and cleaning to avoid electrical shock. 6-1. Replace the battery In the event that a symbol appears on the display when operating the meter, the battery must be replaced.
How do you use a commercial electric multimeter to check voltage?
- Toggle the dial to. m is also included in some digital multimeters (DMMs). Set the range to the highest voltage setting and the dial to if the voltage in the circuit is unknown.
It’s worth noting that most multimeters start up in Autorange mode. Based on the voltage present, this automatically determines a measurement range.
- To begin, connect the black lead to the COM jack.
- The red lead should now be inserted into the V jack. Remove the leads in the following order: red first, then black.
- Connect the test leads to the circuit in this order: black first, then red.
Caution: Do not touch the lead tips with your fingers. Allowing the tips to communicate with one another is not a good idea.
- Check the display for the measurement. When you’re done, remove the red lead first, then the black lead.
Step-by-step instructions on how to use a multimeter
Before you begin, double-check that your multimeter is in good working order. This may appear to be an afterthought, but it’s a crucial step when utilizing an electrical tester. Checking your equipment might help you avoid electrical shock if something goes wrong.
Make sure the area you’re evaluating is completely dry. On the multimeter, look for cracks and any fraying or nicks in the wires. If your equipment is damaged, don’t test it. Wear rubber gloves and shoes with rubber soles if you want to feel even safer when testing.
It’s critical to double-check that your probes are working internally now that you’ve ruled out evident harm. This is referred to as “ohming-out the leads” by some.
- Set the selector knob on your multimeter to the ohm meter.
- Connect the black probe to the universal port.
- The red probe should be inserted into the ohms jack.
- Tap the red and black tips together gently. While doing so, avoid touching the metal pieces with your fingers.
- Your reading should be less than 0.5 ohms.
- Replace the probes if your reading is higher than that.
What are the multimeter’s settings?
In the DC range, set the knob to “20V.” (the DC Voltage range has a V with a straight line next to it). In most cases, multimeters are not autoranging. You must set the multimeter to a measurement range that it can handle. 2V, for example, refers to voltages of up to 2 volts, whereas 20V refers to voltages of up to 20 volts. Use the 20V option if you’re measuring a 12V battery. Is it a 5V system? Set the voltage to 20V. If you set it improperly, the meter screen will most likely change and read ‘1’.
With a digital multimeter, how do you measure voltage and resistance?
1. Resistance testing
- Turn off the circuit’s electricity.
- Choose your level of resistance.
- The black test lead should be plugged into the COM jack, while the red test lead should be plugged into the jack.
- Connect the probe tips to the component or section of the circuit where the resistance is to be determined.
How do you use a multimeter to check for a short circuit?
How to Use a Multimeter to Find a Short Circuit
- Preparation and safety are two important factors to consider.
- Set the Multimeter to Continuity or Resistance and turn it on.
- Check the Multimeter’s Function.
- Locate and identify the circuit component.
- To use the Probe Tips, place them on the circuit.
- Examine the Multimeter’s Display.
