Q: Does it measure inrush

If you use the min/max function and put it on max amps and the reading you get will be your inrush current reading. Hope this helps.

Q: What is the difference between the cl390 and the cl380 meter?

They are very similar, the CL390 has the additional probe holder on the clamp to assist with one hand operation and a slightly different design layout.

Q: In which country is this product manufactured?

The vast majority of the Klein tools are made in the USA. The exact percentage changes frequently as the insource of some products to their USA plants and new products lineup get added. Klein has introduced many new US-manufactured products in recent years (hole-making, screwdrivers, fish tapes, utility wrenches, buckets, bags, etc.). Klein tools has invested in four new US manufacturing facilities in the past decade, and have invested heavily in new equipment and tooling in their plants to expand our capacity and quality.
