一、使用及校准中出现的问题分析依据JJF1101-2003《环境试验设备温度、湿度校准规范》,环境试验设备主要参数有温、湿度偏差,波动度以及均匀性。本文就围绕以上参数,并结合平时经验,简单分析设备在使用和校准过程中出现的问题。1.温度过冲温度过冲问题主要是由于设备的控温系统和加热系统本身的设计缺陷或参数设置不合理导致的。老式的温度试验设备配置的是位式调节的温度控制仪表,位式调节的控制原理为温度达到设定值时,控制
First, the use of and calibration problems analysis based on JJF1101-2003 “environmental test equipment temperature and humidity calibration specification”, the main parameters of environmental testing equipment temperature and humidity deviation, volatility and uniformity. This article will focus on the above parameters, combined with the usual experience, a simple analysis of equipment in the process of using and calibration problems. 1. Temperature overshoot Temperature overshoot problem is mainly due to the device’s temperature control system and the heating system itself, design flaws or parameter settings caused by unreasonable. Old-style temperature test equipment configuration is a bit-regulated temperature control instrument, bit-conditioning control principle for the temperature reaches the set value, the control
