Hello Alfik and thank you for the post.
Unfortunately to accurately measure current up to
2000 A you will need the TA167 clamphttps://www.picoauto.com/products/curre ... rent-probe
As soon as we exceed the maximum input of the current clamp our test results cannot be relied upon as the clamp will simply reach saturation point.
You could use a x1 probe setting and voltage scale (+-10 V) for your 600 A clamp rather than the 600 A probe setting (amp scale)
Here you will then be able to view the waveform beyond the 600 A input but the data and information obtained cannot be relied upon.
I hope this helps, take care......Steve
