Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

High Voltage, Inc. designs and manufactures industry-leading high voltage test equipment for proof testing, diagnostic testing, high voltage breakdown testing, and preventative maintenance testing.

AC testing of electronic systems often requires a low-distortion signal source to excite a DUT (device under test). Instead of using a signal generator and a power amplifier to produce a ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

Proper calibration of test instruments is crucial for meeting the stringent performance requirements of many equipment types. Calibration results must frequently meet national and international ...

HVI has led the industry in manufacturing the most portable and easiest to use VLF test instruments since 1998. The E Series represents the apex of these efforts with the most advanced features and ...
