Air conditioner installation

Previously I used a tester. I use this because it is troublesome to take out two tester sticks and use them after using them.

I have loved it for more than 5 years. Because it is compact, it is caught in a notebook with a ballpoint pen. When you want to judge whether the voltage is 100V or 200V, you can immediately distinguish it immediately. Also, it is surprisingly convenient for the tester to distinguish between 200 V single phase and 200 V displayed as the same 200 V in the lamp display as well. Roughly a pocket star, I use it as a tester if I want to investigate further.

I chose not to use batteries. I was worried about the brightness of the neon tube, but it was clear brightness.

It was smaller than I expected. I wanted the size of the ballpoint pen.

It is convenient because it fits in a small chest pocket, I am very happy because I was searching from before.

Although the former is stating, at the time of 200 V at single phase 3 wires, both can be inserted, 100 V will be lit so you can check it 100 V is only one lighting so you can easily check it is easier It is easy to check with the tester without chest It is a very good product because it can be stabbed in your pocket. Just drop it or you will be damaged so I'm buying it for a while (; _;)

The one I used to use was new, so I wanted something new as it was about to break. It does not require battery replacement and is convenient to use. Thank you very much.
Liveness check during electric construction

A very small neon tube type electrosurgical instrument as much as the index finger. However, depending on the application, it may be too small to handle. It is interesting that rough judgment of 100V and 200V can be made by neon tube type, but because it is a neon tube type, there are times when it is not accurate by human body · shoes · building resistance value. Also, in the case of a single-phase three-wire system which is currently main- tained in a house, since the ground voltage is 100 V even when the line voltage is 200 V, it is necessary to confirm with the tester whether the last is 100 V or 200 V.
