Introduction of how to use a digital multimeter. Selecting measurement parameter, switching ranges, and connecting test leads.
The first digital multimeter was introduced in the late 1970s, and has proven much more accurate and reliable than the old needle-based analog meters. It’s used primarily to measure voltage (volts), current (amps), and resistance (ohms). But that’s just the beginning of what this ...
Using a multimeter to test DC voltage, AC voltage, resistance, and current is crucial in various electrical and electronic tasks. Measuring DC Voltage Essential for checking batteries, power supplies in electronic circuits, and solar panels. Accurate DC voltage measurements ensure devices operate at ...
The difference between an analog multimeter and a digital multimeter comes down to the display and what they measure. An analog multimeter measures voltage (volts), resistance (ohms), and current (amps). The dial on the display (which looks like a VU meter) reacts with magnetic fields create...
Wave and Tide Generation: Wave energy generators use the motion of waves to operate an electric generator. Tidal generators are like undersea windmills and use the flow of water during rising and ebbing tides to turn giant under water "propellers". Like a windmill, the propeller is connected to...
Here at SparkFun, we use 9V power supplies for many of our products that operate in the 3.3V to 5V range. However, to verify what voltages are safe, it is recommended that you check the datasheet for the voltage regulator on the development board to see what voltage range is recommended...
AC/DC current probes use a transformer to measure AC currents and a Hall-Effect device to measure DC current. Since they include active electronics to support the Hall-Effect sensor, AC/DC probes require a power source to operate. This power source can be a separate power supply or may be...
The lack of parameter testing is seldom a problem because these components will have been tested at manufacture and it is comparatively rare for the performance to fall to a point where they do not operate in a circuit.Most failures are catastrophic, rendering the component completely inoperable....
elevators and airliners almost always use CAN-bus due to a number of factors including how long the communication wires can be without data corruption. Cars, elevators, aircraft, robotics and other systems all use CAN-bus because of its ability to operate with one pair of wires but hundreds ...
Shunt configuration for a current sense resistor For this approach to be able to operate satisfactorily, it is necessary to know the resistance of the shunt sensing resistor as well as that of the ammeter. It is then easy to work out the overall current flow. For ease of calculation,...
