KDP-BA_IA-e-1710 149 AdjustmentAs the acceleration value due to gravity is not the same at every location on earth,every digital weighing platform must be coordinated - in compliance with theunderlying physical weighing principle - to the existing acceleration due to gravity atits place of location (only if the weighing system has not already been adjusted to thelocation in the factory). This adjustment process must be carried out for the firstcommissioning, after each change of location as well as in case of fluctuatingenvironment temperature. To receive accurate measuring values it is alsorecommended to adjust the digital weighing platform in weighing operation.• Prepare the required adjustment weight. The adjustment weight to beused depends on the capacity of the weighing system. Carry outadjustment as near as possible to the weighing system’s maximumweight. Info about test weights can be found on the Internet at:http://www.kern-sohn.com.• Observe stable environmental conditions. Stabilisation requires a certainwarm-up time.Performance of adjustmentAdjustment can be initiated using the commands "JZ", "JG" as well as "JS" in theKCP protocol.1) Emptying the weighing pan.2) Sending the command to adjust the zero point ("JZ").The balance sends a confirmation ("JZ A").3) Place the adjustment weight specified in chapter 1 on the balance.(query the adjustment weight using the command "JDC")4) Send the command to accept the adjustment load ("JG").The balance sends a confirmation ("JG A").5) Save the adjustment using the command "JS".This chapter 10.1 describes the ideal way to adjust the balance using theBalanceConnection software.
