按照传统的方法,利用标准温度灯对工作范围为800～2000℃的目测高温计进行分度和检定时,规定要分别在800,900,…,2000℃等指定的温度点上,依次使高温计上的线状灯丝与标准温度灯上的带状灯丝的亮度相等。在这种情况下,每隔100℃,温度灯都必须在此温度下保持5～10分钟;这时光度测量和读 According to the traditional method, when the standard temperature lamp is used for indexing and checking the visual pyrometer with the working range of 800-2000 DEG C, it is stipulated that the pyrometers should be sequentially placed on the specified temperature points of 800, 900, ..., 2000 DEG C, Of linear filaments equal the brightness of ribbon filaments on standard temperature lamps. In this case, the temperature lamp must be kept at this temperature for 5 to 10 minutes every 100 ° C; at this time, the photometric measurement and reading
