A meter is any device built to accurately detect and display an electrical quantity in a form readable by a…
As was stated earlier, most meter movements are sensitive devices. Some D’Arsonval movements have full-scale deflection current ratings as little…
Every meter impacts the circuit it is measuring to some extent, just as any tire-pressure gauge changes the measured tire…
A meter designed to measure electrical current is popularly called an ”ammeter” because the unit of measurement is ”amps.”. Ammeter…
Just like voltmeters, ammeters tend to influence the amount of current in the circuits they’re connected to. However, unlike the…
Though mechanical ohmmeter (resistance meter) designs are rarely used today, having largely been superseded by digital instruments, their operation is…
Most ohmmeters of the design shown in the previous section utilize a battery of relatively low voltage, usually nine volts…
Seeing as how a common meter movement can be made to function as a voltmeter, ammeter, or ohmmeter simply by…
Suppose we wished to measure the resistance of some component located a significant distance away from our ohmmeter. Such a…
No text on electrical metering could be called complete without a section on bridge circuits. These ingenious circuits make use…
