## Questions & Answers

**Q: Will this device qualify a cat5/6 cable as 10m , 100m, or 1000m (1g) rating?**
A: This is a simple device not made for qualifying the cables but simply testing a line.

**Q: Does it save test results? can they be saved and printed?**
A: No, results are only shown on the screen after the test is run. Running another test or shutting the device clears the previous results. No saving of results or printing them from the tester. As another person suggested, if you need to keep a record of results using this device you'll need to do something else like take a picture of the display with your phone.

**Q: I'm looking for a network tested that will aquire an IP automatically from a DHCP server. Will this perform this task?**
A: No it will not it does not have that capability to do so.

**Q: Does it come with MAC address?**
A: No MAC address

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best!
*by J***O on September 2, 2025*

Very useful and has a lot of functions. The head phones look cheap tho.

### ⭐ 初期不良の粗悪品。中国へ自費で
*by N***I on September 12, 2025*

開封後電源をつけたらつかずアダプターを変えて試してもだめで初期不良品でした。みると返品先が中国となっており送料はこちらで負担することになっていました。その送料はAmazon負担で良いのではないでしょうか。

### ⭐⭐⭐⭐ 新品？ ほぼすべてのテストができるが、日本語マニュアルがほしい
*by G***I on December 16, 2023*

製品自体は優秀で、ネットワーク関係のケーブルでは、ほぼすべてのテストができます。（cate6まで） 特に気に入ったのが以下のとおり。 ・調べたいＬＡＮケーブルがＨＵＢのどこのポートに繋がっているかわかる。 ・ＬＡＮケーブルの長さが10cm単位でわかる。 ・PoEの電圧がわかる。 ・複数芯ある光ファイバーケーブル(SC端子・シングル・マルチ)のどの端子同士が繋がっているかがわかる。 ただ、マニュアルが英語のみなので、ネットで日本語解説のものを取ってくる必要があります。 また、残念ながら、液晶画面に保護シールが無く傷だらけだったのと、一番重要なＬＡＮのSCANポートがおかしかったので、返品。新品では無かった可能性がある。 追記：再度購入。傷もなく今回は新品と思われる。 性能に問題なし。
