To zero out weight on display, open receiver box in control panel. Switch rotary dial to 1. This should change display screen to set Dta. Dta is the minimum limit. Set to 0 with no load on the hook. Small buttons on receiver near rotary switch are + and -. Once it’s zero and, hold both buttons until the remote display says “result: success”. Dtb is the maximum limit and both need calibrated to be accurate on display. Dtb needs to be 50% of maximum load.
