The Olympus SP-720UZ Digital Ultra Zoom was released alongside the SP-620UZ to provide snap-happy consumers with something a bit more cultured that the standard digital cameras. While this camera is not able to reach the heights of a DSLR, it is still a worthy camera for travellers and those looking to capture fun shots.

The 720UZ is not the most aesthetically pleasing digital camera on the market but is solid and functional. It is built with a plastic body with a rubber grip that makes it comfortable to hold. As a bit of a throwback, the flash comes folded down, requiring you to manually lift it up to use.

The 3 inch LCD screen is one of the outstanding features making this one of the best digital cameras It is bright, and clear enough to be visible in low light conditions. The sheer size of the screen means that there is barely any room for anything else on the back of the camera save for a D-pad, menu, playback and record buttons. The latter comes encapsulated in a nice rubberised grip to prevent finger slipping. The top of the camera features the usual mode dial and on/off buttons. Settings and menus can accessed via the LCD screen and are easy to use, which is good for anyone moving up from a mobile phone camera. (more...)

PAT testing is a process of checking the electrical appliances for safety in many countries. It is also known as Portable Appliance Testing. Organizations ranging from businesses to public administrations and educational institutions use this process to have “in service inspection and testing of the electrical appliances.

Safety of the students in schools is always a priority for the authorities. The usage of information technology and Internet is much more rampant in universities and schools. Due to the number of computers being used on daily basis, there is a huge need for safety testing of these appliances. These computers are used by students and this increases potential risk for them. PAT Testing is a must for the schools and universities for the protection of students.

PAT testing is used by landlords to ensure safe usage of the electrical equipment by their tenants. The landlords are responsible for the safety of all the portable appliances and their properties they are going to rent out. Many portable appliances are mostly the main appliances in everyone's kitchen like fridge, freezer, oven and microwave. These portable appliances should be checked for safety to ensure the tenants well-being. Every appliance should be maintained and should be PAT tested before letting out the property to the tenant. Other appliances like Television, radio, iron, washing machines and dishwashers should also be PAT tested. (more...)

One small electrical mistake can lead to death which is why you need to hire someone who knows proper precautions and will know how to take them. (more...)

Instrumentation has evolved as a separate branch of science and technology that deals with several electronic / electrical test equipments. These test equipments are used to generate and capture back test digital / analogue signals from the devices under test. Different types of test equipments are an inseparable part of all the branches of engineering.

There are some basic equipments such as voltmeter used to measure voltage difference, ammeter used to measure current in ampere and multimeter that combines voltmeter and multimeter together. Some of the advanced meters used in the industry includes satellite meters, capacitance meters, optical power meters, LCR meters, frequency counters, RF power meters / sensors, insulation / resistance test meters.

There are several types of analysers such as audio analysers, modulation analysers, network analysers, optical spectrum analysers, logic analysers, spectrum / signal analysers that are used by engineers in advanced testing methodology. Attenuators and RF switches are also used by electronic engineers working with radio frequency or RF technology. It is for an engineer to find many of these testing equipments and even if found, it might be too costly to purchase. If you are an engineer or technician looking around for any of the various types of test equipments then you can find it online for sale or rental at MCS Test Equipment in UK. (more...)
