有两种方法可以确定腹板张力与负载上测得的力之间的比率单元格，通过悬挂重量或计算。
•带悬挂重量（菜单悬挂重量）将一根绳索准确地沿着腹板路径拉紧，并施加已知重量。
应用的已知重量模拟实际腹板张力和电子测量施加的重量对称重传感器产生的合力。
当腹板张力（T）和相应的测量力（FR）已知时张力电子设备计算T/FR比率，并将该值存储为缠绕增益。
当卷筒张力应用于辊时，张力电子设备通过以下方式计算卷筒张力将测得的称重传感器上的力乘以包裹增益。
3BHE035301R1002励磁系统模块悬挂重量程序完成后，张力电子设备计算的包裹增益可以可在EnterWrapGain菜单中找到。按计算（菜单输入Wrapgain）
包裹增益是一个比例因子，对应于腹板张力（T）和作用在称重传感器测量中的腹板张力的分力（FR）方向
包裹增益范围为0.5-20。如果尝试将包裹增益设置在此范围之外，则显示屏上将显示消息“WrapGainTooLow”或“WrapGainTooHigh”。
包裹增益可设置为分辨率0.01。
描述缠绕增益计算原理的示例：可以设置以下参数：•过滤器设置）
•高压（N、kN、kg、lbs、N/m、kN/m、kg/m、pli），（出厂默认值=2000 N）
•高输出（出厂默认值=+10 V）
•低张力（N、kN、kg、lbs、N/m、kN/m、kg/m、pli），（出厂默认值=0 N）
•低输出（出厂默认值=0 V）
•上限，（出厂默认值=+11 V）
•如果电压输出信号过快或为了补偿滚动不平衡，可使用下限（出厂默认值=-5 V）滤波。
滤波器为线性相位型，最大平坦，20 dB/十年。
There are two ways to find out the ratio between web tension and measured force on the load
cells, by Hanging weights or by Calculation.
• With hanging weights (Menu HangWeight)
String a rope that follows the web path exactly and apply a known weight.
The applied known weight simulates the actual web tension and the electronics measures
the resulting force on the load cells caused by the applied weight.
When both web tension (T) and the corresponding measured force (FR) are known the
tension electronics calculates the ratio T / FR and stores the value as Wrap Gain.
When web tension is applied to the roll the tension electronics calculates web tension by
multiplying the measured force on the load cells with the Wrap Gain.
After the hanging weight procedure the wrap gain calculated by the tension electronics can
be found in the EnterWrapGain menu.By calculation (Menu EnterWrapGain)
Wrap Gain is a scaling factor which corresponds to the ratio between Web Tension (T) and
the force component (FR) from web tension that is acting in the load cell measuring
direction.
The Wrap Gain range is 0.5 - 20. If you try to set the wrap gain outside this range, the
message “WrapGainTooLow” or “WrapGainTooHigh” will be shown on the display.
The wrap gain can be set with a resolution of 0.01.
