The term "electronic tools" pertains to both electronic testing devices as well as electrically-powered tools. While the two types of tools are vastly different, many repair shops use one or both of the electronic tools on a nearly daily basis. One of the most common types of electronic testing devices is the circuit tester. This device is used to determine the amount of electricity, if any, that is present or circulating through a device or power line. One of the most common and most used electronic tools, not including the flashlight, is the electric drill.
When a repair person begins any type of repair on an electrical device, the first step is commonly to use electronic tools to verify that power is reaching the affected area of the device. This is done to demonstrate that the reason for the defect is not related to a power loss. Circuit testers, ohm meters and volt meters are just a few of the many electronic tools used to check for the presence and amount of power that is available at a power source. In addition to testing certain parts for damage, these meters and testers also prevent accidental electrocution by allowing the repair worker check for the presence of electricity prior to beginning work.
Electric tools can be either battery-operated or corded models, with the later being the least common on most job sites. Drill motors, several types of power saws and sander/grinders are just some of the various types of electronic tools used by repairmen and home handy persons on a regular basis. Other types of electric tools that are commonly used in or around a repair shop or job site are air compressors, electric nailers or nail guns, and screw guns or screw drivers. The advances made in the area of battery power have made cordless tools a common sight on job sites. With the aid of a battery charger and one or two reserve batteries, a quality cordless power tool can easily last the entire work day without fail.
Armed with a selection of cordless power tools and spare batteries, a repairman can often complete a day's work order without having to stop to charge batteries or string an extension cord. This makes many jobs go much faster and eliminates some of the trip-and-fall hazards from the job site. The use of battery-powered, electronic tools also reduces the risk of electrical shock when working in wet areas or in a light rain.
