| More than twenty years ago, IBM designed a computer system for small office appiications. No one at that time could have foreseen the revo...
| Use this handy instrument to check out the resonance frequency of those unknown or home-brew inductor / capacitor combinations, or as a si...
| The mains voltage level is dangerous, and possibly lethal to touch, so that extreme caution is required whenever you work on wiring or com...
| Since measuring liquids with a direct voltage quickly leads to catalysis effects and corrosion, the gauge uses a rectangular voltage. The...
| Since measuring alternating voltages and currents is not a straightforward matter, it is not to be wondered at that errors occur frequentl...
| The audio-video processor is constructed on four printed circuit boards: potmeter board, measuring 314.5x159.5 mm, mother board, measurin...
| Measuring a current without affecting the circuit in which that current is flowing is an ideal test method. Current-sense power MOSFETs are...
| Most capacitance meters have no facility for measuring large electrolytic capacitors. The circuit described here makes it possible for s...
| It is an unfortunate but well-known fact that measuring the active power of a mains-powered apparatus can be quite tricky. While non-reactiv...
