To re- ceive accurate measuring values it is also recommended to adjust the balance peri- odically in weighing operation. CWS-BA-e-0610... - Page 15 * The adjustment should be made with the recommended adjustment weight (see chap. 1 "Technical data"). Weights of different nominal values may be used for cali- bration but are not optimal for technical measuring.
