数据更新周期数据更新周期是模块显示新数据所用的时间每个通道。对于四个输入电路，此周期不超过2.4ms；对于一个8输入电路配置，该周期不超过3.0ms。自动校准

在适当的时间执行内部自动校准过程（如有必要）以补偿前端漂移的信号处理。自动校准功能采用反馈机制调整参考电压，以抵消模数转换器。校准在后台持续监控并在必要时进行调整。下图显示了自动校准所有五个输入范围的点数。自动校准点由上的粗点表示坡度线。

自动校准过程使用10 V参考电压校准模块。这个参考电压出厂时预设为10伏（归零至四位）。它应每年在该领域进行一次调整。

输入数据转换输入模块对输入模拟信号进行模数转换12位分辨率（即4096中的1部分）。这意味着输出代码对应于略大于满量程的0.024%。下图是用于绘制模拟输入的粗粒度转换图以原始二进制格式输出到PC的等效数值。这个所示示例显示了1.25 V（5 V FSR的25%）的输入电压和通过455斜线投影的1024个数字（4200的25%）。

使用以下比例方程计算精确值：其中，FSR是模拟输入（包括双极）的满标度范围，FCR是满标度原始二进制格式的计数范围（4200）

Data Update Period The data update period is the time taken by the module to present fresh data for each channel. With four input circuits, this period is no more than 2.4 ms; for an eight input circuit configuration, this period is no more than 3.0 ms. Autocalibration An internal autocalibration process is executed at appropriate times (if necessary) to compensate signal processing for front end drift. The autocalibration function employs feedback mechanisms to adjust the reference voltage to offset gain in the analog to digital converter. Calibration is monitored continuously in the background and adjusted if and when necessary. The following figure shows autocalibration points for all five input ranges. Autocalibration points are indicated by heavy dots on slope line. The autocalibration process uses the 10 V reference to calibrate the module. The reference voltage is factory preset to exactly 10 volts (zeroed to four places). It should be readjusted in the field once per year. Input Data Conversion The input module performs an analog-to-digital conversion of an input analog signal with 12 bit resolution (i.e., 1 part in 4096). This implies that the least significant bit of the output code corresponds to slightly more than 0.024% of full scale. The following illustration is a coarse grain conversion chart for plotting analog input against the equivalent numerical value output to the PC in raw binary format. The example illustrated shows an input voltage of 1.25 V (25% of 5 V FSR) and a numerical count of 1024 (25% of 4200) as projected through the 455 slope line. Calculate exact values using the following proportional equation: Where FSR is full scale range for analog input (including bipolar) and FCR is full count range (4200) in a raw binary format
