Current measurements are not as handy as voltage measurements. You typically need to either measure the voltage across something and do some math or break the circuit so a known resistor in your ...

A battery-operated volt-ohm-meter (VOM), or multitester, is a simple, relatively inexpensive testing device that's well worth acquiring if you plan to do electrical repairs. A VOM can tell you whether ...

Inrush current effect is common in electric motors. Sometimes, in case of ill-designed electrical wiring systems, switching on the motor may activate the fuse. It is caused by the inrush current – ...

A current probe isn’t a very common fixture on most workbenches because they are pretty expensive. [VoltLog] looks at a fairly inexpensive current probe from Micsig. He seemed impressed with the ...

Wires and cables tend to behave as transmitting antennas. When troubleshooting a system for EMI, you must identify which cables have these undesirable “common mode” currents. Current probes let you ...

Multimeters. They've been described as the tape measure of the new millennium. But what exactly is a digital multimeter (DMM) and what can you do with it? How do you make measurements safely? What ...

Tektronix introduced the P6042 current probe in 1969, priced at $625 ($4100 in 2016 dollars). It has a probe you can clamp onto a wire carrying current. The output of the P6042 goes to an oscilloscope ...

Teledyne LeCroy introduced a 1000-A RMS AC-DC current probe designed for accurate, high-current measurement in applications ...

Aim-TTi has developed a current probe which is cable of measuring currents in PCB tracks. Measurement of current normally requires either the insertion of a shunt resistor, or for the conductor to be ...
