以下是一份關(guān)于3452-12指針兆歐表的產(chǎn)品中英文介紹：

3452-12指針兆歐表是一款由日本日置（HIOKI）公司生產(chǎn)的高精度絕緣電阻測試儀器。該產(chǎn)品具有多種實(shí)用功能和特點(diǎn)，使其在電氣設(shè)備的絕緣檢測中表現(xiàn)出色。它配備了熒光式刻度盤，即使在光線較暗的環(huán)境中，也能方便用戶清晰讀取測量數(shù)據(jù)。此外，3452-12還具備活線確認(rèn)功能，能夠幫助用戶快速判斷電路是否帶電，從而提高測試的安全性和準(zhǔn)確性。該兆歐表還設(shè)計(jì)了電池低電量檢查功能，避免因電量不足導(dǎo)致測量中斷，同時(shí)具備放電功能，可在測試結(jié)束后安全釋放被測設(shè)備上的殘余電荷。

從技術(shù)參數(shù)來看，3452-12提供了三種測量電壓選項(xiàng)，分別是125V DC、250V DC和500V DC，能夠滿足不同設(shè)備和場景下的絕緣電阻測試需求。其有效測量量程及公差分別為：在125V DC時(shí)，指示刻度的±5%在0.02MΩ～10MΩ；250V DC時(shí)，±5%在0.05MΩ～20MΩ；500V DC時(shí)，±5%在0.1MΩ～50MΩ。此外，該儀器還可測量交流電壓，量程為0～500V（50/60Hz），公差為滿量程的±5%。

3452-12指針兆歐表的體積小巧，重量僅為420g，便于攜帶和操作，非常適合在各種現(xiàn)場環(huán)境中使用。其電源由4節(jié)AA電池（R6P）供電，進(jìn)一步增強(qiáng)了其便攜性。此外，該儀器還配備了測試探頭（9292）和攜帶盒（9384），方便用戶進(jìn)行測試操作和設(shè)備存儲。

The 3452-12 pointer megohmmeter is a high-precision insulation resistance testing instrument produced by HIOKI, a company based in Japan. This product features a fluorescent dial, which allows users to read measurement data clearly even in dimly lit environments. In addition, the 3452-12 is equipped with a live wire confirmation function that enables users to quickly determine whether a circuit is energized, thereby enhancing the safety and accuracy of the testing process. The device also includes a low battery check function to prevent measurement interruptions due to insufficient power, as well as a discharge function that safely releases residual charges from the tested equipment after the test is completed.

In terms of technical specifications, the 3452-12 offers three measurement voltage options: 125V DC, 250V DC, and 500V DC, catering to the insulation resistance testing needs of various equipment and scenarios. The effective measurement range and tolerance are as follows: at 125V DC, the tolerance is ±5% of the indicated scale within the range of 0.02MΩ to 10MΩ; at 250V DC, ±5% within the range of 0.05MΩ to 20MΩ; and at 500V DC, ±5% within the range of 0.1MΩ to 50MΩ. Moreover, the instrument can measure AC voltage with a range of 0 to 500V (50/60Hz) and a tolerance of ±5% of the full scale.

The 3452-12 pointer megohmmeter is compact in size and weighs only 420g, making it easy to carry and operate, and is suitable for use in various on-site environments. It is powered by four AA batteries (R6P), further enhancing its portability. Additionally, the device comes with a test probe (9292) and a carrying case (9384), facilitating test operations and equipment storage for users.
