配備自動置零和零點跟蹤裝置的電子汽車衡
，將示值擺脫自動置零和零點跟蹤范圍（如加放10e砝碼），然后按照閃變點方法計算零點誤差，也可以通過鍵盤指令或開關(guān)等正常方式使自動置零或零點跟蹤裝置暫時不起作用，再按閃變點方法計算零點誤差。
確定除皮裝置的準確度，應(yīng)在承載器上加放某一重量的載荷，然后啟動除皮裝置運行，把示值調(diào)整為零，再按閃變點方法計算除皮操作后的“零點”誤差；若除皮裝置的準確度測試后直接進行除皮稱重測試，該“零點”誤差即為修正誤差中的eo（ec=e-eo）。

equipped with auto electronic truck scale zero and zero tracking device
equipped with auto electronic truck scale zero and zero tracking device, the indicating value out of automatic zero and zero tracking range （such as adding 10e weight）, and then in accordance with the flash point method to calculate the zero error, can also through the keyboard commands or special switch normal mode enable automatic zero or zero tracking device temporarily can not afford role, then press the flicker point method to calculate the zero error.
determines the accuracy of the peeling device, should be in the carrier and load of a weight, then start peeling device operation, the value is adjusted to zero, then press the flash point method to calculate the peeling operation after the zero error; if the accuracy of the test in addition to skin directly after removing device skin weighing test, the zero error is the error correction in the eo （ec=e-eo）.
