6.1 Calibration
Two steps are required for executing calibration:
1. Enter/write calibration value (see chapter 3.4.1.6 Positioning and chapter 8
Communication via SIKONETZ5 Parameter address 0x1F)
2. Execute calibration (reset) (see chapter 2.4 Keys, chapter 3.4.1.6 Positioning or chapter 8
Communication via SIKONETZ5 Parameter address 0xA0)
Since the measuring system is an absolute system, calibration is necessary only once with
commissioning. With calibration, the calibration value is adopted for calculation of the
position value. The following equation is applied in case of calibration:
Position value = 0 + calibration value + offset value
Calibration value (see chapter 4 Parameter description Parameter no. 26)
Offset value (see chapter 4 Parameter description Parameter no. 25)
