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. Operation using a rechargeable battery (optional) Lift-off the battery cover on the lower side of the balance. -
Page 11: Adjustment
The required adjustment weight depends on the capacity of the weighing system. Carry out adjustment as near as possible to the scale’s maximum weight. Info about test weights can be found on the Internet at: http://www.kern-sohn.com Observe stable environmental conditions. Stabilisation requires a certain warm-up time. -
Page 12: Linearization
Observe stable environmental conditions. Stabilisation requires a certain warm-up time. Do not remove adjustment weight in steps 1 to 3 during linearization, only increase it. After successful linearisation you will have to carry out calibration; see chapter “testing instruments control”. KDE-T-BA_IA-e-1210... -
Page 13: Carry Out Linearization
“F” will appear briefly before the weighing scale turns itself off. Linearization has now been completed successfully. We recommend that you adjust the weighing scale after linearization.
