Zero-Flux Current Sensors: Like in "Back to the Future"?

cookmesomekai

Do you remember the "flux capacitor" that Doc Brown invented in "Back to the Future"? It was the core component in that iconic DeLorean which - after supplying it with 1.21 GW of energy - would allow Marty McFly to travel through time. The "flux capa...

DC Current Measurement and Bandwidth

cookmesomekai

All you needed was a precise sensor to measure DC current, and after talking to HIOKI you ended up ordering a 10MHz AC/DC current sensor... Does HIOKI employ sales magicians who can sell ice to eskimos? Or does bandwidth simply also matter when measu...

Current sensors: How much is the drift?

cookmesomekai

Some time ago HIOKI created a short video in which we briefly compared hall-sensor based current sensors with fluxgate based sensors: https://youtu.be/OrmbFCCWrhI In the video I said that "every hall sensor in the world has a DC drift" and ...

Low resistances: Key to high performance batteries

cookmesomekai

To be firmly pushed back into your seat when kicking down the “accelerator pedal” in an electric sports car, the high-voltage battery pack needs to feed a high current to the electric drive motor. This in turn requires batteries that have...

A dedicated resistance meter? Here is when it makes sense...

cookmesomekai

Measuring DC resistances is one of the functions pretty much every bench multimeter provides. Then why would you need a separate resistance meter? One of the best digital multimeters available on the market offers a lowest resistance range of 1 Ohm. ...

AC/DC clamp meters versus AC-only models (when measuring AC current)

cookmesomekai

If you want to measure the current consumption of a device that runs on a half-rectified alternating current lile a hair-dryer on the "half-power setting" then an AC/DC clamp meter will give you a much more precise reading than an AC-only clamp meter...
