High-precision digital intelligent instrument
① 24 bit A / D converter. With five ten thousandths of accuracy and display resolution of one hundred thousandth of 1 to 20 times per second can be set to take into account the different tranches and control speed high resolution and speed of measurement and control application needs. There are 3 levels display brightness can be adjusted. 16 para polyline features. with maximum and minimum memory function. 3:00 switch inputs and four buttons can be individually programmed to implement the specified functions.
② anti-jamming design, inhibit the rapid burst interference relays, contactors, etc. produced by the scene and other electromagnetic interference, immunity to level III
(Within the range of -20 ℃ ~ 50 ℃) ③ Drift: Meter internal reference is less than 5ppm / ℃; thermocouple, RTD, DC mV input is less than 10ppm / ℃; DC current, DC voltage input is less than 30ppm / ℃, if the user this requires two kinds of signal drift higher, and may make special order when ordering.
④ Input signals include: thermal resistance (Pt100, Pt1000), temperature range of -200.00 ℃ ~ 500.00 ℃; thermocouple (K, S, E, T), resolution is 0.1 ℃; DC current; DC voltage; DC mV
