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.

电阻元件使用特殊选择的合金电阻丝无感缠绕在高质量成型器上。每个电阻元件都经过热处理，并经过受控的老化过程，以产生最高的稳定性和较低的温度系数。

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.

开关质量很好，具有低压触点，使用寿命长且可靠。每个十进制开关均采用全封闭结构制造，可实现免维护作。这些十进制盒装在带有可伸缩提手的精美坚固的金属箱中。

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 型号具有zui低的十进制，步长为 1mΩ。这对于电阻温度计仿真和电阻电桥网络特别有用。所有型号都有一个额外的端子连接到静电屏，这在交流电桥应用中可能需要。

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 系列十进制电阻盒由 10 台仪器组成，涵盖高达 1,111,111Ω 的电阻范围，仪器有 4、5、6 和 7 十进制可供选择。虽然成本低，但这些仪器质量很好，具有精密、低接触电阻的开关。

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.

电阻元件由漆包锰丝制成，无感缠绕在高质量成型机上。每个电阻元件都经过热处理并经过受控老化过程，以产生最高的稳定性并实现低温度系数。这些仪器装在一个有吸引力的金属外壳中，既坚固又防尘。
