快速设置可以通过两种方式进行，具体取决于包裹增益的设置方式。可通过选择“悬挂重量”或“进入包裹增益”来设置包裹增益。•使用吊重，见第3.8.1节使用包裹增益，参见第3.8.2节。悬挂重量精确地沿着卷筒纸路径并施加已知重量的绳子。所施加的已知重量模拟实际的幅材张力，并且电子设备测量由所施加的重量在称重传感器上产生的力。当已知卷材张力（T）和相应的测量力（FR）时，张力电子设备计算比值T/FR，并将该值存储为包裹增益。当卷筒纸张力施加到辊上时，张力电子设备通过将测得的力乘以卷绕增益来计算卷筒纸张力。在悬挂重量程序之后，由张力电子设备计算的包裹增益可以The fast setup can be made in two ways, depending on how the wrap gain is set. The wrap gain can be set by selecting “HangWeight” or “EnterWrapGain”. • Using Hanging Weights, see Section 3.8.1. • Using Wrap Gain, see Section 3.8.2. Hanging WeightString 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
