Gauss meter only covers the measurements of the magnetic field, unlike the emf meter that covers the measurements of both electric field and magnetic field. It measures the magnetic flux density, expressed in Tesla, Gauss, or Newton per meter. The magnetic field depends on the current flow. If a wire connects to a power source … Read more
Signal generators are testing equipment used in different applications. The most common ones include testing complex communication systems, measuring the frequency response of amplifiers, and aligning the frequency response devices. You may need a signal generator for designing, testing, and troubleshooting electronics circuits. Unlike function generators capable of producing multiple waveforms, signal generators are limited … Read more
An oscilloscope provides you with more information than the standard multimeter (both analog and digital) by graphically showing you the waveform of voltage that can then be analyzed for some properties such as frequency, amplitude, rise time, time interval, distortion, pulse width, and others. Based on the display, there are two types of oscilloscopes available. … Read more
A function generator is unavoidable if you are an electrical circuit designer, technician, or product quality auditor. As the name suggests, function generators produce electrical waveforms for testing other equipment and systems. They are one of the most commonly used in test and development systems. Function generators come in all forms, and different types also … Read more
A tally counter is a tool to count the events. The mechanism can be either a digital or mechanical. In some cases, it can be a software or app, which is installed on your devices. Typically, a mechanical tally counter is encased with metal material to protect the internal mechanical components. A digital tally counter, … Read more
An hourglass functions similarly to a timer. It’s a tool to give you a certain interval time. However, unlike a digital timer that you are probably able to change the time interval, the time interval of hourglasses is fixed. In addition, although it’s said 10 minutes, for example, you should never expect it as accurate … Read more
Simply, a tape measure holder is an accessory to temporarily store your tape measure while working. When it’s not being used, you can store it in your holder. It’s commonly placed around the waist by hooking it on your pocket or belt. In some cases, the holder comes with slots where the belt weaves through … Read more
Setting a grade for any construction project generally requires a survey instrument. However, you can also set elevations with a simple string line level. Property owners, contractors, and landscapers usually need to set elevation grades on their land. Elevation grades layout is vital to provide drainage away from your building. This helps in avoiding pond … Read more
Levels and plumbs are important for many home-improvement projects. Post level is one of the vial based levelling tools that you need to use at times. Post levels ensure that your vertical spaces are plumb and horizontal surfaces are level. You can use post levels to see the level of a countertop and shelf. At … Read more
If you are a DIYer or electrician, you will need electrical tape for insulating cut wires when doing home electrical repair or fresh installation. But that is not a problem because you can do it with conventional electrical tapes. What if you are performing the same task in tight and hard-to-rich spaces? The usual taping … Read more
