High speed and high precision data processing QD77MS4 User's Manual.
The processing speed of the real number (floating point) arithmetic has been greatly improved,
Addition instruction reached 0 QD77MS4014 mu s,
Therefore, it can support the request of high-speed, high-precision processing data processing.
In addition, the new addition of double precision floating point arithmetic instructions,
Simplify the programming, reduces the computational error when executing complex formula QD77MS4 User's Manual.
Shorten the fixed scan interrupt time, high precision device.
The minimum interval of the fixed period interrupt program is reduced to 100 s.
The high speed signal can be accurately obtained, which makes the contribution to the higher precision of the device.Input: 2 channels.
Input: thermocouple / micro voltage / voltage / current.
Conversion speed (input):25ms/2 channel QD77MS4 User's Manual.
