Measure The Voltage And Current Using Digital Multimeter

Wednesday, February 24th, 2010

Multimeter to an electrical engineer is same as machine gun to a soldier. Not only to the engineers, multimeter is an essential device for the homeowners those who handle the repairs and replacements of electrical appliances. All Digital Multimeter will test for voltage, current and resistance. These are the three functions you will use most when trying to diagnose a problem.

With the advancement in technology both the analog and digital multimeter are available but the more accurate and easy to use is the digital ones. Since, these are more frequently used in carrying out basic electrical home improvement jobs; one should know how to use your digital multimeter.

Of all the functions, a multimeter can carry out checking of DC voltage to be measured. The red lead is plugged into the red voltage jack and the black one to the common jack. Keep the red lead on the positive terminal and the black on the negative. We can read the DC voltage on the dial. Make sure that while measuring a DC volt whose value is not known, the dial switch is set at the highest range.

By setting the dial switch to the mini volts position; plug in the red probe to the red jack and the black to the common and placing the red lead on the positive side and the black on the negative, we can even read mini volt range of DC.

Testing the AC voltage using the multimeter is also a usual phenomenon when dealing with the home improvement task. For this, plug the red probe into the red voltage, Ohm, diode jack. Plug the black probe into the com jack. Hold the red probe on the positive side of the AC voltage source and hold the black probe to the negative side.

Similarly, AC voltage ranging some mini volts can also be tested using the digital multimeter.

We can also measure AC and DC currents using digital multimeter. DC current can be read by placing the red lead to the ampere jack and black to the common jack. DC current range of 200mA to 10A can be measured by connecting the red lead to 10A jack and the range switch set on the desired DC A position. The circuit whose current is to be measured has to be opened for this purpose. The leads are to be connected in series to the circuit load.

Be careful while handling the multimeter. Do not set the multimeter on the resistor setting and touch the probes to a voltage source. Never touch the probes to a voltage source with the probes plugged into the A and milli- ampere probe jacks.

How To Use Lighting To Improve Your Home’s Security

Sunday, December 20th, 2009

Many people know that having adequate lighting can put off criminals from your home. If you make proper use of the right kind of lighting, you are going to make any would-be burglar or intruder of any type think twice about coming into your house, making it a safer place for your family.

Outside The House:

Lights on the outside of your home are vital. This is especially true for any doorways at the rear of you house, because this is where break-ins tend to happen the most. All round security lighting that is set-up high out of reach, and is tamper proof, will greatly improve your home security and help to protect your house.

You also need to provide lighting in carports and garages. If you have the option, get and use an automatic garage opener. All the best garage door opener fitted today use a light that operates when the opener is activated, lighting the garage interior. In carports, it is best to leave a light on permanently, have a light on a timer, or use a motion sensor to activate the light.

It is best to use a motion detector on all outside lights that are not left switched on. The primary benefit of a motion light for your home’s security, is that when the light turns on, you know there is someone or something in the area of the light. And despite the complaints of a lot of people, if you set the sensitivity of your motion detector properly, it wont be going off any time the wind blows too hard, a squirrel runs across your yard, or the dog or cat moves around. When it comes to the front yard, you want to make sure that the light will cover the entire front and side of your house, no matter what kind of light you decide to use. You can use motion sensors on these lights, simply like the ones in the rear of your house, but they are more prone to being incidentally triggered by people coming to visit, or kids playing.

Inside:

When you go out and do not expect to return until after dark you probably, like most of us, leave on what the police refer to as burglar beacons. Basically, a burglar beacon is an individual light that is left on inside your house, so that when you come back it isn’t completely dark.

Unfortunately, these lights indicate to potential burglars that you are out for the evening. In order to improve the security of your home when you are out for the evening, instead of a single light you should have several lights, and a source of noise, that are set on timers all over the house to come on at various times to give the impression that someone is there.

Need For A Home Security System

Wednesday, December 2nd, 2009

Home alarm systems are responses to rising rate of burglary. Apart from banks and depository, your homes are one of the best places to preserve your most treasured things and investments. Hence a system is needed to protect your home from intruders.

Home alarm system can be a do-it- yourself project. Since, the system is expensive and elaborate, it is better to call in a professional. It employs a horn or a sought of a bell that start jingling when the motion of the intruder is detected.

Place or install the hooter in the area where you can easily detect the perceiving sound. The added advantage of the system is, even the power breakdown can’t stop the working of the alarm. This is because the alarm switches over to the battery power when the power is cut off.

This security system contain a magnetic- switch circuitry where one part is the magnet and the other is the relay. The loop continues to be in the close state when the magnetic- switch connection is maintained. It gets broken as the two split up. There separation causes the buzzer to trigger.

Switch mainly constitutes of a magnet and a relay fondly called as switch. The magnet- switch loop maintains the connection. As long as the connection persists, the circuit remains closed and as the two are separated, the connectivity is broken thereby activating the alarm.

In general, the magnetic part of the switch circuit is located at the doors and windows and the relay is connected to the bay and the door frame. If someone tries to even break open the door the magnet- switch circuitry will split apart raising the buzzer.

Moreover, the buzzer also contain a switch that is used to deactivate the sounder. In addition to this, you need to reset the complete system for the next time. Many home alarm systems also have features like glass- break sensors and motion detectors.

Home alarm systems also associate additional fees and is just not about the initial cost. But it is better to bear the high cost of the system than to take risk with our precious life and depository as well.
