I guess my killaWatt can't measure start up current. AC .... are there any cheap clamp on or other style devices that can and work well?I have an automobile unit but that is too big..
Klein Tools CL440 Clamp Meter is an advanced HVAC clamp meter with automatically ranging true root mean square (TRMS) for maximum accuracy. The meter measures AC current, inrush current, AC/DC voltage,
I’ve got a Kaiweets HT208D which works great for measuring peak inrush. Seems to be a good meter if you just need to know the peak value.
I need more information about a load, though, I need an oscilloscope to measure the duration of the inrush surge. Can anyone recommend a cheap usb probe that will do the job for a 240V load?
To clarify, the HT208F and HT208D are the same meter and they both do inrush and have all the same functions. The only difference is that the HT208F has a monotone LCD screen that is visible in direct sunlight, while the HT208D has a full color screen that does not work so well in direct sunlight.
