传感器和探针表面之间的距离

d) geometry of the sensing element;

传感元素的几何尺寸

e) type of instrument; 仪器的类型

f) dimensions of the instrument; 仪器的尺寸

g) electrical supply (battery, mains).电力供应(电池, 主要)

9.3.2 Minimum requirements 最小要求

The following minimum requirement shall be satisfied:

以下最小要求应当被满足

measurement accuracy better than 10 %.

测量准确度好于10 %

9.4 Visible light measurement 可视光测量

See EN ISO 3059:2001. 见标准EN ISO 3059:2001

When measuring the visible light from UV sources, the luxmeter shall be insensitive to UV and infrared radiation.

当从UV光源测量可视光时，光度计应当是对红外和紫外辐射没有影响。 Appropriate filters shall be incorporated. 适当的过滤器应当被合并。

9.5 UV-A irradiance measurement UV-A光照度测量

See EN ISO 3059:2001. 见标准EN ISO 3059:2001

9.6 Verification and calibration of instruments

仪器的证明和标定。

The verification and calibration procedures for instruments shall be carried out so that during the calibration interval

the measuring error remains within limits given in this standard.

对仪器的证明和标定过程应当被实施以至于在标定间隔期间，测量错误保持在这个标准给出的限制之内。

This shall be done, following the recommendations

of the manufacturer of the instrument and in accordance with the quality assurance system of the user.

应当这样做, 遵照仪器制造商的推荐和与用户的质量管理系统符合。
