SmartTrace BK120 サーキットブレーカーファインダー＆ソケットテスター Fluke

I am an electrical engineer and have been using Fluke test gear for decades. This device is another example of the old saying, "if it works, it is a Fluke" I had another brand of this kind of device, but it failed to located the correct breaker a number of times, forcing me to go back to the old method of just turn off a lot of breakers and see if the power was off at the spot I needed to work on. This one on the other hand has worked exactly as expected, and It does give me another voltage detector to scan wires to insure power if off, or at least which ones are the hot wires. This one is a keeper!

NOT SUITABLE for European market...

I choose Fluke for test equipment. Pricey but a cut above the rest. I also use Hioki and Kyoritsu. Other brands I let my friends borrow indefinitely. The BK120 SmartTrace Breaker Finder comes with a Quick Reference Guide, a double-sided sheet of water-resistant paper with pictorial instructions for an international audience. Visit Fluke's website to download their Users Guide that explains in English language how to use the BK120, including tips for resolving ambiguous readings that are not mentioned in the pictorial Quick Reference Guide. Fluke also has a webpage ("How do I find where my breaker goes?") that explains less content in English language. I recommend the Users Guide. Here's an excerpt from their Users Guide (9/2023, Rev. 2, 10/24 (English)), only text, no drawings: --begin excerpt-- Breaker and Fuse identification To identify a breaker: 1. Plug the Transmitter into the socket (See Figure 3.). 2. Turn ON the Breaker Finder and slide the function selector to BREAKER FINDER position (See Figure 4.). 3. Hold the Breaker Finder perpendicular to the breakers and scan slowly at the breaker panel with the flat surface of the tip end directly on the circuit breaker. During this scan, it may beep and/or have visual indication at several breakers as it measures the relative signal strength during the first scan process (See Figure 5.). Note: Inaccurate reading may occur if the tip is placed at any other angle. 4. Repeat step 3 for the second scan, solid green indication illuminates when the Breaker Finder identifies the breaker that is powering the Transmitter (See Figure 6.). For optimal results or if the Breaker Finder detects two adjacent breakers on the second scan, reset the Breaker Finder, and turn the Breaker Finder 180⁰ (see Figure7). Repeat step 3 and 4. 5. To confirm you have found the correct breaker, trip off the breaker and check that the Transmitter in the socket is off (See Figure 8.). --end excerpt-- By "turn the Breaker Finder 180⁰" Fluke means holding the tester in your other hand (that is, your left hand instead of your right). Shopping tip: If you are considering buying a Fluke 1AC II VoltAlert Non-Contact Voltage Tester and a Fluke ST120 GFCI Socket Tester, then instead buy a Fluke BK120 SmartTrace Breaker Finder and Socket Tester (the product of this review) because you get the functionality of both devices plus a circuit breaker finder. Costs more, gets more. I do not know whether the ST120 and BK120 transmitter are identical other than the ST120 being rated up to 300V while the BK120 transmitter is limited to 150V. The 2 devices look almost the same (see my photo of them side by side). I simultaneously plugged in both kinds to different electrical outlets, and the BK120 tester identified each circuit on the breaker panel. This is not how you are supposed to use the device -- I did this because I was curious. Good luck to all of you.

Mejor que el klein tools, super recomendado fluke.

Muito bom o produto. É Fluke. Funciona perfeitamente. Como o produto é importado, o padrão de tomada veio diferente do Brasil mas nada que um adaptador não resolva.
