Page 15: Start-Up
6.5.1 Start-up Turn on scales with ON/OFF switch (left). The balance will carry out a self-test As soon as the weight display shows "0" in all the three display windows your balance is ready to weigh. On CXP models (with RS 232) an internal number appears before the balance counts down to zero. -
Page 16: Linearisation (Verified Models Only)
6.6 Linearisation (verified models only) Linearity shows the greatest deviation of a weight display on the scale to the value of the respective test weight according to plus and minus over the entire weighing range. If linearity deviation is discovered during a monitoring of test resources, you can improve this by means of linearization. - Page 17 Operation After the adjustment switch having been set to position “ADJ” switch-on balance.
