Each input signal is programmed to enlarge, 24-bit resolution A/D conversion, photoelectric isolation sent to single-chip processing.

Thus, the interference between each input channel and the interference between the input channel and the CPU are completely eliminated.

High precision digital temperature sensor is used to compensate the cold end temperature of thermocouple. To improve long-term stability

Qualitative, this recorder abandoned the traditional potentiometer to adjust the magnification and zero method, instead

Software program adjustment method, and the realization of the program-controlled magnification magnification. Before the factory factory for all parameters are

The debugging is complete. The system error can be corrected by translation through keyboard setting.
