DS-3000U DS3000 User Guide Figure 9: Wiring for Program Example 1 9.1.3 Programming Summary 1. Configure the DS-3000 remote input to “reset” and “tare” the displayed value at program start. “Reset” means, output #1 will be reset to it’s default state, and will remain there until triggered. “Tare” means to automatically zero the results at whatever the current load value is. 2. Set the threshold to activate relay #1 at below the tare value say -10 lbs 3.
