The ZX74 Series of Decade Resistance Boxes are very high accuracy and stable six-dial instruments. There are 4 versions in the series with a maximum resistance of 1,111,111Ω. The ZX83 series adds another two Decade Boxes that extend the resistance range to 111,111,100Ω.

ZX74系列十進(jìn)制電阻箱是精度非常高、穩(wěn)定的六刻度盤(pán)儀器。該系列有 4 個(gè)版本，最大電阻為 1,111,111Ω。ZX83 系列又增加了兩個(gè)十進(jìn)制盒，將電阻范圍擴(kuò)展到 111,111,100Ω。

The resistive elements are non-inductively wound on high quality formers using a resistance wire of specially selected alloy. Each resistive element is heat treated and undergoes a controlled ageing process to produce the very highest stability and also a low temperature coefficient.

電阻元件使用特殊選擇的合金電阻絲無(wú)感纏繞在高質(zhì)量成型器上。每個(gè)電阻元件都經(jīng)過(guò)熱處理，并經(jīng)過(guò)受控的老化過(guò)程，以產(chǎn)生最高的穩(wěn)定性和較低的溫度系數(shù)。

Switches are of the highest quality with low pressure contacts for long life and reliability. Each decade switch is manufactured using a fully enclosed construction for maintenance free operation. These decade boxes are housed in attractive robust metal cases with a retractable carrying handle.

開(kāi)關(guān)質(zhì)量很好，具有低壓觸點(diǎn)，使用壽命長(zhǎng)且可靠。每個(gè)十進(jìn)制開(kāi)關(guān)均采用全封閉結(jié)構(gòu)制造，可實(shí)現(xiàn)免維護(hù)作。這些十進(jìn)制盒裝在帶有可伸縮提手的精美堅(jiān)固的金屬箱中。

The very popular ZX74 model has a lowest decade with steps of 1mΩ. This is particularly useful for Resistance Thermometer Simulation and resistance bridge networks. All models have an extra terminal connected to the electrostatic screen which may be required in AC. bridge applications.

非常流行的 ZX74 型號(hào)具有zui低的十進(jìn)制，步長(zhǎng)為 1mΩ。這對(duì)于電阻溫度計(jì)仿真和電阻電橋網(wǎng)絡(luò)特別有用。所有型號(hào)都有一個(gè)額外的端子連接到靜電屏，這在交流電橋應(yīng)用中可能需要。

The ZX90 Series of Decade Resistance Boxes comprise of 10 instruments to cover a resistance range of up to 1,111,111Ω with instruments available in 4, 5, 6 and 7 Decades. Whilst they are low cost these instruments are of high quality and feature precision low contact resistance switches.

ZX90 系列十進(jìn)制電阻盒由 10 臺(tái)儀器組成，涵蓋高達(dá) 1,111,111Ω 的電阻范圍，儀器有 4、5、6 和 7 十進(jìn)制可供選擇。雖然成本低，但這些儀器質(zhì)量很好，具有精密、低接觸電阻的開(kāi)關(guān)。

The resistive elements are made of enamelled manganin wire which is non-inductively wound onto high quality formers. Each resistive element is heat treated and undergoes a controlled ageing process to produce the very highest stability and to achieve low temperature coefficient. The instruments are housed in an attractive metal case which is both robust and dust proof.

電阻元件由漆包錳絲制成，無(wú)感纏繞在高質(zhì)量成型機(jī)上。每個(gè)電阻元件都經(jīng)過(guò)熱處理并經(jīng)過(guò)受控老化過(guò)程，以產(chǎn)生最高的穩(wěn)定性并實(shí)現(xiàn)低溫度系數(shù)。這些儀器裝在一個(gè)有吸引力的金屬外殼中，既堅(jiān)固又防塵。
