一、特性:
ke4400热工信号校验仪主要是为工业现场热工仪表及系统的校验维护而设计的，仪表提供完善而实用的功能，操作简单。仪表采用单片机作为cpu ，集最新大规模数字转换集成电路和大屏幕液晶显示技术于一体，具有输出、测量、手册和24vdc 配电功能，且四项功能可同时工作，同屏显示输出和测量值以及对应的its-90标准值（热电阻和热电偶）。并配备超大容量可充电电池，携带方便，能方便地完成工业现场热工仪表（传感器、变送器、显示仪表、控制系统）的检修、校验。
二、热工信号校验仪使用特点：
■ 小巧、便于携带和手持。
■ 坚固、可靠，背面的支撑架和挂钩孔适合现场使用。
■ 大显示屏，测量、输出可同时显示。
■ 电压、电流、电阻的测量和电压、电流的输出。
■ 8 种热电偶（k 、 e 、 t 、 j 、s 、 r 、 n 、 b）的测量和输出， 2 种热电阻（ pt100 、cu50 ）的测量。
■ 热电偶、热电阻的测量输出具有its-90 国际标准毫伏、电阻值对应显示。
■ 电压和电流测量可显示百分比。
■ 热电偶测量、输出具有自动或手动补偿功能。
■ 输出值的输入采用多种方式。
■热工宝典可实现电阻值与温度值、毫伏值与温度值的快速互查。     
■ 内置大容量充电电池，充电一次可连续工作5～7 小时（与工作状况相关）。
■ 大屏幕液晶带背光显示，中文菜单操作。
■按键声音和背光可控制，并能才每次开机时保持上次最后设置的状态。
