Klein Tools Circuit Analyzer RT390 – Features
If this seems familiar, that’s because it is similar in form factor to their RT310 GFCI/AFCI outlet tester. The RT310 was more advanced than your basic outlet tester. Not just because it could test AFCI and GFCI outlets but because it had an easy to read “display” and more could provide more data that just isn’t available on basic outlet testers. However the “display” was really just lights to indicate the wiring state of the outlet. It was not an actual display such as the LCD’s found on many gadgets today.
That’s where the RT390 circuit analyzer comes in. It features a similar form factor to the RT310 and brings along its features. However it adds an actual backlit LCD display and some extra features.
The cord used to plug into an outlet is detachable for easy storage. This also makes it easy to replace in case it gets damaged. It using a cable also has the advantage over regular outlet tester. This is because it will be able to easily fit all types of outlets including recessed outlets. The cord also allows you to hold and and face the display in your direction. No matter the outlet is located low on the ground or above you.

Klein Tools Non Contact Voltage Tester with Laser Distance Meter NCVT-6 Honest Review
The detachable cord looks to be a standard cord used for a lot of electronics so it would also allow you to add a longer cord if you were using the tester in a confined area or you just wanted to have a long cord. I have even seen 25 foot cables.
Very true!
