Is there a true RMS clamp meter that actually records the highest ampacity read?

When testing, the inrush ampacity only lasts a fraction of a second, is there a way to make sure the highest current is picked up?

Is Fluke the only way to go?

So many brands out there these days

What are general reviews on the Klein CL2000 True RMS?
In my opinion Fluke is the only meter I would trust for anything critical.

In my experience Klein meters are cheap junk. I have a Klein mm200 multi-meter that I use as my beater throw around meter for troubleshooting fire alarms. It was cheap and if I drop it and it breaks, I can just go buy another one for $50. I would never trust it for anything where accuracy or my safety were involved. For that I take out my good Flukes.

To answer the original question, my Fluke 381 does inrush. Also the removable screen and 2500 amp flexible donut are nice features. It isn't cheap though. Some where around $450-$500 if memory serves.

My fieldpiece sc56 is trueRMS and does inrush. Fieldpiece is geared towards HVAC guys but it should do more then you need. I picked mine up for about $200. A few of there cheaper meters might even do inrush. They make good meters and stand behind them.

The Amprobe ACDC-400 Also looks interesting

But is it true RMS?

From the data sheet:

Max input 600 VAC rms
Max current 400A rms continuous; 600 A rms ( 60 seconds)

I find it hard to beleive there are electricians that dont have a fluke 1750. I usualy throw one away after every job so I dont have to haul it back to the truck.
yeah I go through at least one a year

theyre definitely cheap enough to use as throw aways

I have 10 of them, if you want to trash them send them to me I need to purchase two more.
