The meter probe must be clamped around the wire of the tested circuit and the knob must be set appropriately, depending on the current type: AC or DC. In the case of distorted waveform current, it is ...

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

Measuring current is always a nuisance because you have to break the circuit to put the measuring device in series with the circuit. That problem never goes away. Still, any high-end digital ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

Hi everyone, my english is not very good, but I'll try to be as clear as possible. I have a dc clamp meter UNI-T 219ds and wrongly applied voltage on current position. This position is used for all ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

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 – ...
