    Establishing Tares Overview The TARE function can be disabled (OFF), set to function as a push-to-tare (PTT) that acquires the weight on the platter when the TARE button is pushed, or can be set so tare values are entered digitally with keypad buttons (SET).
  • Page 17 TARGET key TARGET When the CW-80 is set up in Target operating mode, pressing the TARGET key acquires the weight on the scale as the desired target value. The CW-80 then computes the Under and Over values around this target value based on tolerance settings defined in the Setup mode. ID key The ID key is used to call up and activate a particular ID number and its Over/Under/Tare/Units register.
