How to read a multimeter

For example if youre measuring a 15V battery you would move the dial to 2V because this is the next number up thats displayed on the multimeter. The trick with voltage meters is that as long as you have a completed circuit you should get the same reading regardless of where you connect it.

MAGS How To Videos - How To Use a Multimeter For BeginnersIn this video I will help teach you how use a multimeter to test volts AC DC amps and ohms.

How to read a multimeter. Reading an Analog Multimeter Result 1. Find the right scale on an analog multimeter. Analog multimeters have a needle behind a glass window which moves to.

Make a voltage scale reading based on your range. Look carefully at the voltage scales either DC or AC. Estimate the value between.

In this video I go through the basic functions of a cheap multimeter I cover how to measure AC and DC Voltage how to measure resistance how to test for co. The reading on the multimeter has the same value but its negative. Measuring voltage in a circuit.

In this example well show you how to measure the voltage drop across a resistor in a simple circuit. This example circuit lights up an LED. If your multimeter reads close to zero the range is set too high for a good measurement.

Turn the dial to a lower setting. If you set the range too low the multimeter simply reads 1 or OL indicating that it is overloaded or out of range. This wont hurt the multimeter but we need to set the dial to a higher range.

So if you have your multimeter set to 20 in the DCV section the multimeter will measure voltages up to 20 volts. Your multimeter will also have two or three ports for plugging in the probes pictured above. The COM port stands for Common and the black probe will always plug into this port.

Here are the steps to take. If the system is on carefully check VCC and GND with the voltage setting to make sure the voltage is the correct level. Power the system down and check continuity between VCC and GND.

If there is continuity if you hear a beep then youve. Power the system down. Connect your analog multimeter to the first resister on your circuit coming from the negative pole and to the positive pole on the same resister.

The trick with voltage meters is that as long as you have a completed circuit you should get the same reading regardless of where you connect it. Set the dial to the next number up from the voltage youre measuring. For example if youre measuring a 15V battery you would move the dial to 2V because this is the next number up thats displayed on the multimeter.

If youre not sure of the voltage of the thing youre measuring set the dial to a higher number. If your multimeter shows a high number then something is wrong with your multimeter and you probably will not have accurate results. Again make sure your resistor is not connected to any circuit or power source.

Take your black and red lead and connect them to opposite ends of the object you are looking to check resistance on the resistor. To read an electric dial meter correctly. Read the dials from left to right.

If the pointer is between the two numbers always take the lower number. If the pointer is directly over a number write down that one. If the pointer falls between 9 and 0 write down 9 and reduce the reading youve.

To read your Landis and Gyr electricity meter press B to light the screen up. You should be given the option for a meter boost - press A to select No and then you should be able to see your electricity reading. To read your gas meter press either A or B to wake up the screen.

This should automatically come up with your gas reading. A multimeter or a multitester also known as a VOM volt-ohm-milliammeter is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage current and resistance.

Analog multimeters use a microammeter with a moving pointer to display readings. Digital multimeters DMM DVOM have a numeric display and may also show a. MAGS How To Videos - How To Use a Multimeter For BeginnersIn this video I will help teach you how use a multimeter to test volts AC DC amps and ohms.

Auto-ranging multimeters automatically adjust to the voltage or ohm setting needed to test the component or circuit. With a conventional manual multimeter the user would either know beforehand or rotate the dial to find the appropriate range. Start at a high value and move the dial down until seeing the appropriate range.

How to read an Economy 7 smart meter This type of meter takes records day and night usage. Press 6 on the keypad until the letters IMP R01 followed by eight digits appear usually your nightoff-peak reading. Keep pressing 6 until you see IMP R02 followed by eight digits usually your peaknormal reading.

Pressing button 9 on the meter keypad will supply read information. A single button press will show the Total read for use if you have a single rate tariff displayed as IMP kWh followed by the read itself in kWh this will time out after approx 4 seconds and move to the next screen. Read the dials from left to right.

Ignore the dial marked 110. If the pointer on a dial is between two numbers write down the lower number. But if the pointer is between zero and nine it will always be nine.
