The 5-digit high-precision intelligent digital display controller has a 24-digit A/D converter; it has an accuracy of 5/10,000 and a display resolution of 1/100,000; the sub-level measurement and control speed can be set from 1 to 20 times per second Taking into account the different application requirements of high resolution and measurement and control speed; the display brightness can be adjusted in 3 levels. 16-segment polyline function. With maximum and minimum memory function; 3-point switch input and 4 buttons can be individually programmed to achieve designated functions. The anti-interference design can suppress the rapid pulse group interference and other electromagnetic interference generated by the relays and contactors in the field, and the anti-interference ability reaches level III. Temperature drift (within the range of -10℃~50℃): ·The internal reference of the instrument is less than 5ppm/℃; ·Thermocouple, thermal resistance, DC mV input are all less than 10ppm/℃; ·DC current and DC voltage input is less than 30ppm/℃; ·If the user has higher requirements for the temperature drift of these two signals, special order can be made when ordering. Input signals include: thermal resistance (Ptl00, Pt1000 three-wire or four-wire system, jumper selection is available), the temperature measurement range is (-200.00~500.00)℃ Thermocouple (K, S, E, T), resolution is 0.1℃; DC current; DC voltage; DC mV.
