求翻译：当“自动上限校准”=66时按SET键，校准远程设定信号的上限值。输入上限信号20MA或10MA（此时S4E=1），通过键盘修改S20=66按SET键，校准远程设定信号的上限值，使外部设定最大值是“输入20ma流量”是什么意思？

When the "automatically limit calibration" =66 press SET key, calibration of remote setting the upper limit of the signal value. Input maximum signal 20MA or 10MA (S4E=1), modified S20=66 by using the keyboard press the SET key, calibration of remote setting signal top, so external set the maximum v

When “automatic upper limit calibration” =66 presses the SET key, the calibration long-distance hypothesis signal on limiting value.Input upper limit signal 20MA or 10MA (this time S4E=1), revises S20=66 through the keyboard to press the SET key, the calibration long-distance hypothesis signal on li
