Instruction you Must follow while working with electrical test equipment

several electrical appliances put under trial are practiced through the so called “testgear” or the electrical study tools which is utilized mainly to make the signals and also to acquire the assorted reactions.By this way, a proper action of instrument under test can be established and errors can be probed and mended.
These electric trial equipment are very useful and also essential for any type of grave work required on the electronic systems. Practically electronic test tools need the use of different kinds of tools varying from the easy and reasonable to extremely complicated and refined tools like Automatic Test Equipment. Generally, a excellent test gear is wanted when developing circuits and systems as compared to construction testing or when troubleshooting for production units obtainable in the field.

The following equipment are applied for basic sum of currents, voltages and components in the electric circuit under study.
•Ohmmeter: This equipment ckecks the resistance.
• Voltmeter: An equipment that ckecks voltage.
•Ammeter, e.g. Milliameter or Galvanometer- measures current
• Digital Voltmeter: This equipment measures resistance, voltage and current.

Following are the apparatus that are used for circuit stimulus:
• Signal Generator
• Power Supplies
• Pulse Generator
• Pattern Generator

To analyze the reaction of electric circuit under testing, the following tools are used:
• Frequency Counter: helps in measuring frequency
• Oscilloscope
• testing probes: Rs probes and Signal Generator

Some of the commands that must be followed while working with Electrical Test Equipment are:
• study the electrical test equipment before use and do not use in case they are found defective.
• Electrical test equipment should be used only for proposed applications. Read the functional commands before using the check equipment.
• Electrical test equipment must be confirmed for exact operation instantly before and after use. One should make sure that the electric circuit doesn’t get re-energized by the stored electrical or mechanical energy while working at zero energy checks.
• The energized parts in the circuit that are functioning at a current less than 30 volts or with a potential current that is less than 1 milliamp do not want de-energization.
• The electrical tools that work at as high as 30 volts and have a potential current of about 1 milliamp or more should be completed to undergo de-energization before they are restored.
• the various possible risk judgments should be documented properly and should also include the dangers and the protective instruments gloves, pads, insulated barriers, blankets etc. for all types of jobs.
• The work area should be examined for reliable access and sufficient lighting. Before using electric test equipments, make sure that there are no undocumented hazard obtainable in the work place.
• While working with the electrical machines it is suggested that you should not hold or carry along any conductive ornaments like rings, metal frames, watches, glasses, bracelets, metal covers, etc. In simple words, you should avert carrying things that something that collides with the energized parts.
• hold clothing of natural fiber whenever you are likely to get exposed to high-energy circuit voltages that are above 150 volts to ground.
• In case you obtain any electrical shock, stop working and seek supervisor’s support at the earliest.

You should be extremely cautious when using any of these Electrical test equipments. A trained electrical specialized with a good multimeter can find the cause to nearly every problem.
