Page 18: Scope Of Delivery
7.3 Mains connection Power is supplied via the external mains adapter. The stated voltage value must be the same as the local voltage. Only use original KERN mains adapters. Using other makes requires consent by KERN. 7.4 Battery power supply The optionally supplied battery is charged with the supplied power supply. -
Page 19: Start-Up
7.5.1 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 20: Adjustment With External Weight
7.6 Adjustment with external weight As the acceleration value due to gravity is not the same at every location on earth, each balance must be coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location (only if the balance has not already been adjusted to the location in the factory). -

* The adjustment should be made with the recommended adjustment weight (see chap. 1 "Technical data"). Weights of different nominal values may be used for ad- justment but are not optimal for technical measuring.

Page 26: Parts Counting
9 Parts counting With parts counting you can either count parts into a container or remove parts from a container. To count a greater number of parts the average weight per part has to be determined with a small quantity (reference quantity). The larger the reference quantity, the higher the counting exactness. -
