    ACK and NAK are transmitted according to DIN 66019. A810 will not transmit ACK and NAK. A810 will transmit ACK and NAK enclosed in a block frame made up of STX and ETX. The command takes effect immediately, so command PROTOK is acknowledged already by the newly set protocol.

  • Page 87: Miscellaneous Command

    After command TERMINAL has been transferred all characters contained in a data block are read out by the display of the A810 as far as the display is able to do so. Vice versa the A810 transmits each character entered directly by keyboard to the PC/SPC.

This unit is shown on display after each restart of A810.
  • Page 97 When the loadcell is non-linear, the operator can set additional 3.1.4.2 calibration points. In that example the testweight is 50kg. A810 would show approx. 45kg. To adjust this loadcell error, put testweight on and enter 50.00kg in menu “AddP”. Now A810 shows correct weight.

  • Page 98: Theoretical Calibration

    Theoretical calibration is used for calibration without balance weight. It is possible to enter a known input ratio of an load cell to A810. This procedure is not as accurate as calibration with balance weight because tolerances of components influence the result.
