9 Adjustment
As 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 the
underlying physical weighing principle - to the existing acceleration due to gravity at
its place of location (only if the weighing system has not already been adjusted to the
location in the factory). This adjustment process must be carried out for the first
commissioning, after each change of location as well as in case of fluctuating
environment temperature. To receive accurate measuring values it is also
recommended to adjust the digital weighing platform in weighing operation.
• Prepare the required adjustment weight. The adjustment weight to be
used depends on the capacity of the weighing system. Carry out
adjustment as near as possible to the weighing system’s maximum
weight. Info about test weights can be found on the Internet at:

warm-up time.
Performance of adjustment
Adjustment can be initiated using the commands "JZ", "JG" as well as "JS" in the
KCP 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".
