Programmable timing cycle within range from 1 minute to 96 hours 一分钟到96小时记录时间自由设定 Microprocessor controlled crystal timing regulation定时器由微处理器控制控制 Vastly improved tracking definition 16位液晶实时显示记录参数 Status and Time event count-up displayed on a 16 character LCD Ambient temperature sensor switchable °F or °C with min., max. & current temperature displayed 内置温度传感器，可显示记录过程最高温度、最低温度和当前温度，更准确地了解在什么环境下的干燥过程 Auto stop upon completion of time cycle记录完成，自动关停马达 The Drying Time recorder consists of a stepper motor mounted on a rubber tipped tripod. The arm and ball assembly has a counter-poised vertical stylus consisting of a Teflon 3/8 in. (10 mm) ball stylus and a counter weight to adjust to zero. The Teflon stylus typically under a 12g load (weight supplied) is moved in a 360 degree arc at a pre-selected fixed speed. 干燥时间记录仪由一个步进马达驱动的可以360度自由旋转圆头划针构成机械部分 A shaft arm with Teflon® ball scriber produces a 2" diameter circular path. Drying time is observed and recorded as the ball penetrates the film and produces a circular groove over a period of time. After drying is completed a clear plastic time template is placed over the area so that the drying time record can be converted into minutes or hours.圆头划针在马达驱动下在板子表面按设定的时间划出一个直径为2英寸的圆环，待完成设定的记录时间，覆上同心圆时间尺，即可读取干燥时间或者直接标注该板干燥时间保存。
