Style Name: Remote Disp 1000A TRMS Clamp w/IFlex Verified Purchase
The 381 is one of those tools that fits the description "if this doesn't have it, you don't need it." In terms of what features you'd expect to find on a clamp meter, the 381 leaves little to be desired. The 381 is capable of voltage measurements to 1000V AC and DC with a 1000V CAT III and 600V CAT IV safety ratings. What's all this mean? CAT ratings are specific to a certain section of an electrical system. Meters rated to CAT 3 can work on most switch gear / breaker panels and systems down stream of them (outlets, appliances, hardwired equipment, ect..) CAT 4 is the highest level and adds service drops from the electric utility as well as underground installations. The accompanying voltage is the maximum safe working voltage on these parts of the system. I do not have the information on what the maximum transient voltage / surge voltage this meter is designed to handle happens to be.

The 381 can measure voltage to 1KV on AC and DC systems, and of course has resistance measurements and includes a continuity buzzer. Now this does lack the diagnostic features of an electronics meter but that's to be expected. This is an industrial amp meter. The jaw clamp will take AC and DC current measurements to 999.9A in 0.1A increments. The iFlex clamp will take AC measurements to 2500A in whole numbers but will not take DC current measurements. Unlike other external clamps this uses a proprietary 3 pin connection to connect to the iFlex thus yielding accurate and appropriately quantified measurements. Now bear in mind clamp designs due to their nature of measuring magnetic fields inherently have a margin of error and this one if memory serves is between 2% and 5% depending on the range and frequency of power.

I purchased this meter a month ago to replace my Fluke 337 of 10 years. This meter is a must have for an Industrial or Construction & Maintenance Electrician. The 18" i-Flex easily fits around multiple AWG #500 wires, where last year's meters cannot.

In the Industrial world, the remote face is almost as good as a good apprentice. You can adjust variable frequency drives, view fluctuations in voltage and current, record min/max, with the meter at the equipment, and the display with you at the control panel.

The jaws on this meter are slightly larger than the earlier fluke meters, but not by any huge margin.The white backlight makes the meter extremely easy to read.

The only feature missing on this meter that the 376 model has, is capacitance measurement. Who cares?!?!?!?!

If you're interested in this meter, its a good buy for a serious electrician, and it makes you look intelligent too.

Bought this meter for the iflex functionality and the removable head to reduce exposure to Arc Flash risk. Also find the DC current function on the clamp is very useful for vehicle electrical troubleshooting.

Removable head is very effective.

Love this meter!

This meter replaced an older Fluke - it's a great meter that reduces the need for a separate multi meter in many cases. The high resistance range and fast response have been extremely useful in HVAC troubleshooting. The DC features are invaluable when troubleshooting VFDs and electronics.

Style Name: 600A TRMS AC/DC Clamp Meter Verified Purchase
Very nice meter, good quality as expected by Fluke. Backlit LCD screen is a nice feature.
I work in the automotive industry and was looking for a good clampmeter. Downside of this meter is that it will only go down to 100 milliamps. .1 amp. Thats not sufficient for automotive draw check. The clamp is big enough to get around a door harness , witch the smaller clampmeters cant do. Other features work very well.

I will start off by saying I have a Fluke 83,77 and have been using for years. With that said I needed a dc type clamp as well, so I picked up a 381 kit at the electrical wholesaler , love the Iflex and the remote display. . but the battery only last for a few weeks , even when not in use, I have had to pack a bunch of extra batteries in the case every time i use it. If fluke could fix this problem I would say get it. but if you don't care that every other time you open the case to use it to replace the batteries, get it . Fluke said just remove the batteries when not in use ..really open the case and remove the batteries.? My job is to get in test , fix and get out .not work on my meters I'm a 30 year Master electrician ,and will stay with my other Fluke meters (best in the field) and look for something I don't need to switch batteries on before using

Working in the marine environment makes AC/DC a necessity. The detachable face and iFlex probe make getting into confined spaces on boats a reality with the ability to still read the meter.

Highly recommend!
