Product description:
The automatic test system of 100 - C. 100 - C type thermal automatic verification system is my company newly developed one of the fourth generation of the automatic verification of products.It is under the Windows environment, fully using the language of the Windows environment to develop a new generation of products, the system is a high-end microcomputer as the core, with high-precision digital multimeter, and low potential scanning switch, measurement and control system of power regulator, etc.The operator can be in Chinese to Win95 / Win98 / WinMe operating systems easily with the mouse for the whole process of operation, real-time display calibration furnace microcomputer system (or tank, etc.) of temperature control curve, parameters such as temperature and the test of time.System completely according to the national metrological verification procedures for data processing, and can print all kinds of record form, verification certificate, still can keep original record for future reference.System fully realized the thermocouple and thermal resistance test of full automation of the process, namely: the automatic temperature control, automatic detection, automatic data processing, automatic printing verification results.The operator labor intensity is greatly reduced, and improve the quality of the verification work.This device also provides certification program of the system and the data file management program, the operator of system certification and verification results of the archive, retrieve and query provides the convenience.
