1. The white wire touches the negative pole for 3 seconds to enter the setting speed ratio mode. If the wire leaves the negative pole for more than 3 seconds, it will exit the setting mode
2. When the white wire touches the negative pole, the value keeps increasing; when the white wire is removed and touches the negative pole again, the value keeps decreasing. The longer the white line touches the negative pole, the  faster the value counts. The minimum step value of counting is 0.1, the adjustable range is 1.0-360.
