SY3011徐州三原自动化称重仪表校验
Xuzhou Sanyuan SY3011 Weigh Weighing Instrument
由于给料机是在动态下进行称重计量，经常地校准给料机的零点和间隔是保证其综合计量性能指标的主要方法：
As the feeder is in the dynamic weighing measurement, often calibrate the zero and the interval of the feeder is to ensure its comprehensive measurement performance indicators of the main methods:

皮带秤校准：（空载*速度皮带无跑偏）Belt scale calibration: (no load the maximum speed belt without deviation)
自动建立校准周期：输入皮带长度：Automatic calibration cycle: Enter the belt length:
圈数：Number of turns:
时间：time:
开启皮带速度稳定后，按开始键，跑完后返回。Open the belt speed is stable, press the start button, after the run back.
自动零点校准：运行皮带速度稳定后，按启动按钮，时间为零，按更改。 新零将自动进入仪器，然后返回运行一次。
Automatic zero calibration: After running the belt speed stable, press the start button, the time is zero, press to change. The new zero will automatically enter the instrument and then return to run once.
链码标定：
链码是由若干质量接近的滚轮用链板连起来的一条金属链子。试验校准时，把它放在以皮带秤称重段为中心的皮带上，一端固定。当输送机运转时，链码应在皮带上原地滚动，模拟物料在皮带上的流动，要求链码的长度要完全覆盖计量段的长度，否则会造成皮带秤的计量偏大。
启动输送机，查看链码在滚动时是否跑偏，如果跑偏停机后重新调整，也可将跑偏的一头用铁丝拉住，直到合乎要求为止。
链码标定的关键是量准皮带长度。否则影响日常使用计量精度
Kg/M×L×Q
模拟载荷＝ ------------------
1000
Kg/M——每米链码的标准重量
L——皮带长度（M）
Q——皮带圈数
Chain code calibration:
Chain code is a number of close to the quality of the chain with a chain linked to a metal chain. When the test is calibrated, place it on a belt centered on the belt scale weighing section, with one end fixed. When the conveyor is running, the chain code should be in place on the belt to roll, simulate the flow of material on the belt, the length of the chain code to fully cover the length of the measurement section, otherwise it will cause the belt scale measurement is too large.
Start the conveyor, see the chain code in the rolling when the deviation, if the deviation after the shutdown to adjust, but also the deviation of the one with a wire pulled until the requirements so far.
The key to the calibration of the chain code is to measure the length of the belt. Otherwise affect the daily use of measurement accuracy
Kg / M × L × Q
Simulated load = ------------------
1000
Kg / M - standard weight per meter chain code
L - belt length (M)
Q - belt laps
自动间隔校准：输入计算好的模拟载荷值： ，铺好链码，运行皮带速度稳定后，按开始键，时间归零后按改变，新的间隔值自动输入到仪表，可返回在运行一次。
Automatic interval calibration: Enter the calculated simulated load value: Place the chain, run the belt speed stable, press the start button, the time is zero, press to change. The new interval value will automatically re-enter the instrument.

皮带秤链码校验是模拟实物校验的一种方式，毕竟和实际下料存在皮带张力，震动等等因素的误差。为了减小这样的误差我们可以修改间隔值来弥补。
已知目标值
新的间隔值=———————×仪表现有的间隔值
仪表显示值
把计算出新的间隔值输入到手动间隔校准里，就能达到预计的目标值流量。
Chain code calibration of belt weigher is a way to simulate physical calibration. After all, there are errors in belt tension, vibration and other factors with actual cutting. In order to reduce this error, we can modify the interval value to make up for it.
By inputting the calculated new interval value into manual interval calibration, the expected target flow can be achieved.
