●製品の説明

 横河, 2786, 6 ダイアル可変抵抗器、ディケイド抵抗器
 Yokogawa Electric Works / Type 2786 Decade Resistance Box
 中古品/美品

 0.0 Ω から 111.111 kΩ (111111.0 Ω)
 任意の抵抗値を 0.1 オーム単位で高精度に設定できます。
 抵抗精度を確認済

 美品,綺麗です。
 匿名送料無料(出品者が負担します)



 横河 (YOKOGAWA) 社の、ディケイド抵抗器、Type 2786 です。6 つのダイアルで抵抗値を設定します。設定できる抵抗の範囲は 0.0 Ωから 111.111 kΩ (111111.0 Ω) です。範囲内の任意の抵抗値を 0.1 Ωステップで高精度に設定できます。

 各ダイヤルで抵抗精度は異なりますが、おおむね 0.1% 程度の精度で抵抗値を設定できるので、高精度に抵抗値を設定できます。後ほど、当方で確認した抵抗精度を示します。

 画像に有るように天板に長さ 1cm 程度,塗装の剥げた部分がございます。また,側面の角に白い汚れが有ります。両方とも小さいのであまり目立つことはございません。個人的には中古品ながら大変綺麗だと思います。しかしながら,中古品のため個人差があるといけませんので、詳細な写真を掲載してあります。ご入札前に必ずご自身でもご確認いただけませんでしょうか。

 また、当方、喫煙しませんし、ペットもおりませんので、ヤニ汚れや、におい、引っ掻き傷,ペットの毛の付着などの心配は全くございません。

 経年変化が少なく、また、温度係数も小さくなるよう、高精度に設計してあります。ご参考までに新品時の希望小売価格は、税込み約¥23.7万程度です。

 仕様によると、各ダイアルの抵抗の精度は次の通りです。
 MAX 250V, 0.3W
 0.1ohm ±2%, 1 ohm ±0.5%, 10 ohm ±0.1%, 100 ohm ±0.05%,
 1 kohm ±0.05%, 10 kohm ±0.1%

 外形寸法は突起物を含まず、約 500 * 115 * 140 mm、質量約 3.5 kg です。

 お手持ちのデジタルマルチメーターにおいて、抵抗測定レンジの動作精度確認に利用できます。また、他の未知の抵抗と比較することで、高精度に未知抵抗の値を特定できるようになります。

 当方のデジタルマルチメーター Agilent Technologies 34450A を用いて、出品している抵抗器をテストしました。通常の抵抗値測定よりも高精度に詳細な抵抗値を測定できる 4 線ブリッジ接続のために,ケルビンクリッププローブを使用して測定しました。

 さらに,6 ダイアルを全て用いた計測では、下位の精度が表れにくいため、下位 3 ダイアルと上位 3 ダイアルに分けて計測しました。

 抵抗器のダイアルに設定した値と、マルチメーター 34450A による測定値を比較したのが次の表です。

 新品時の仕様における残留抵抗 23mΩ以下に対して、実測では 16mΩであり,最大値 111.111kΩ時の仕様における許容誤差 0.1% に対して、実測では 0.0612% でした。

 最小値(残留抵抗),および,最大値いずれも充分に仕様を満たしており、すばらしい精度が得られることを確認しました。

Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
