- When testing the grouped live conductors of a circuit, the magnetic fields produced by the load currents cancel each other out. Any imbalance current comes from leakage from the conductors to ground or elsewhere. To measure this current, a leakage clamp meter should be able to read less than 0.1 mA.

Electronics Measurements: What a Multimeter Can Measure Electronics All-in-One For Dummies. A meter is a device that measures electrical quantities in your electronics projects. A multimeter, therefore, is a combination of several different types of meters all in one box. At the minimum, a multimeter combines three distinct types of meters (ammeter, voltmeter, and ohmmeter) into a single device.

- There is automatic bypass, that is spring loaded. It pops on when you pull the meter, and isn't that obvious at a glance. Test/Bypass is a little bit of an odd duck. It's a lot like the way you'd take an old A-Base meter in and out of service. A test/bypass meter has the line and load side bus bars for each phase parallel to one another, with a threaded stud on each bus bar.

Infiltration Test Infiltration Test. An infiltration test will help you determine if the soil on your property is suitable for certain types of stormwater management measures, such as a dry well or rain garden. An infiltration test measures how quickly water can soak in and flow through the soil.ecord the time: 1  Record the amount of time (in minutes) it takes for the 1 inch of water to infiltrate the soil. 2  Stop timing when the surface is just glistening. 3  If the soil surface is uneven inside the ring, count the time until half of the surface is exposed and just glistening.

What are electromagnetic fields? Magnetic fields arise from the motion of electric charges. The strength of the magnetic field is measured in amperes per meter (A/m); more commonly in electromagnetic field research, scientists specify a related quantity, the flux density (in microtesla, µT) instead.

Electricity meter An electricity meter, electric meter, or energy meter is a device that measures the amount of electric energy consumed by a residence, business, or an electrically powered device.n an induction type meter, creep is a phenomenon that can adversely affect accuracy, that occurs when the meter disc rotates continuously with potential applied and the load terminals open circuited. A test for error due to creep is called a creep test.

- Since the source and meter tests loss just like the transmission link, all standard cable plant tests specify using a source and meter to measure loss. You must always use them to test the cable plant loss. Even the outside plant singlemode test standard, OFSTP-7, says you should accept only the source/meter results.

Field strength meter When measuring with a field strength meter it is important to use a calibrated antenna such as the standard antenna supplied with the meter. For precision measurements the antenna must be at a standard height.A value of standard height frequently employed for VHF and UHF measurements is 10 metres (33 ft).he relation between the electric field and the transmitted power [edit]. In ideal free space, the electric field strength produced by a transmitter with isotropic radiator is readily calculated.

Cone penetration test The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils. Based on this history it has also been called the Dutch cone test. Today, the CPT is one of the most used and accepted in soil methods for soil investigation worldwide. The test method consists of pushing an instrumented cone, with the tip facing down, into the ground at a controlled rate (controlled between 1.5 -2.5 cm/s accepted).

Visual Field Test A visual field test is a way to measure your visual field, or how much you can see to each side while focusing your eyes on a central point (peripheral vision). Conducting a visual field test is called perimetry. One measure of your visual function is to read letters on a visual acuity chart. This is a measure of your central vision and is the most critical part of your vision. However, that is only one a measure of your visual function.

- A visual field test can also help the doctor find out more about the part of the nervous system that allows us to see. The visual part of the nervous system includes the retina (the film in the camera-like eye), the optic nerve (the wire that carries images from the retina to the brain), and the brain itself. test that shows visual field loss means that vision in some areas is not as sensitive as normal. It could be just a little vision lost in a small area, or all vision lost in large areas. The amount of vision lost and the areas affected are measured by the visual field test.
