From the early days of electronic design and servicing, engineers and technicians relied mostly on analog meters for measuring voltage, current, frequency, wattage, and most other needed measurements.

Featuring a 51-element tricolor LED meter movement and a three-character digital display, the DNC-PS700-010 pressure differential meter accepts a 0 to 10-in. w.c. pressure. The instrument includes a 4 ...

Power plants use indicators to monitor process parameters such as pressure, flow, temperature, voltage, current, and vibration. Unless a facility is relatively new, it likely has analog panel meters; ...

Paired with the Digital Flowmeter compressed-air meter, the Summing Remote Display allegedly makes it easy to monitor air consumption from a convenient location. Via a pushbutton, the display shows ...

Digital modulation has a lot to answer for. Although the spectral efficiency of communications systems has improved, many signals resulting from digital modulation have significant power variation. In ...

Editor's note: If you're like us and can't bear to part with that crusty old (but magnificent) analog meter, David Ashton offers everything you want to know about these gems in this three-part series: ...
