Review: Good product - This is a good product for its price. It is accurate, it's lightweight and it for sure. Does the job I've had it for over a year now? And it is my go to I do fiber. Optics, so I have to have an accurate version of this, and this one has been an insanely good one. It's durable and can take a beating
Review: Great Tool, useful on the field - I work at a fiber optic internet company, it’s been very useful and it has all my needs on the field. We get optimeters for testing light, they take forever to turn on and there is no VFL on our models. It’s so convenient having instant access to check light levels that you can store in your pocket all the time. The VFL is handy and bright, only downside is after 5-10 minutes it automatically turns off. I wish if the VFL is on then it won’t turn off but it’s not a big deal. I highly recommend calibrating to your fiber optic wavelength and light levels, the out of box experience is good with about 3 DB off but it’s great for a general estimate when it’s not very important. After calibration even after a couple months it’s been accurate and works very well. The battery life is pretty good, it uses 2 AAA batteries and it lasts me about a month or bit more. I love the Ethernet tester that is built onto the removable slot on the bottom. On the field I also work with CAT 6 and it’s great having it on the tool, I never have to carry around a separate Ethernet tester or ever run to my truck to find it. It’s helped me out in situations I never expected. The only major downside I had is the screen. When I first bought it, after about a month half of the screen was not working and was affecting my readings. I exchanged it for a new one and been very careful with the screen and making sure it won’t get dropped or damaged. It’s been a couple months and it’s been working just as it’s new. Overall, I love this tool and it will be a must need for me when I’m on the field.

## Questions & Answers

**Q: what is the max distance this unit will test?**
A: I am assuming you are talking about the laser. From my experience, it is only short distance such as a fiber enclosure. Or pig tail inside the node.

**Q: Is it supposed to come with an adapter for sc and st?  mine came with no adapters.  how to connect st to the meter?**
A: I did not receive one either. I can not find one made for it. But it was pretty accurate compared to my old light meter with blue and green.

**Q: Is there a digital version of the user guide? My unit didn't come with instructions.**
A: Not sure.  The great part is it only does basically 3 things.  play with the buttons for a couple minutes you know more than the manual.  1) cable fault locator (red laser/on off). 2) function key sets db reading (check light level). toggle to RG45 you can check for faults on ethernet.  That’s it, good luck

**Q: What about lc interface ? i work with lc connections most**
A: Lc is can't.It suit for SC/FC/ST.
