Calibration and scaling

Vendor calibration, index 0x80B0:08, 0x80BF:01, 0x80BF:02

The vendor calibration is enabled in the factory setting. It can be disabled via
Index 0x80B0:08 "Enable vendor calibration".

The parameterization of the vendor calibration is carried out via the indices: 0x80BF:01 (offset vendor calibration) and 0x80BF:02 (gain vendor calibration).

	Output error with disabled vendor calibration If you use the user calibration, it may be a good idea to disable the vendor calibration. The vendor reserves the right to carry out the basic calibration of the terminals. Therefore, the vendor calibration cannot be changed.

User calibration, index 0x80B0:07, 0x80B0:17, 0x80B0:18

The user calibration is disabled in the factory setting. It can be enabled via
Index 0x80B0:07 "Enable user calibration".

Parameterization is carried out via the indices:
0x80B0:17 (offset user calibration) and 0x80B0:18 (gain user calibration).

Notice

The user calibration affects the measuring range monitoring.

Incorrect calibration coefficients can lead to the Status bits and Status LEDs no longer behaving as expected; see Output range monitoring.

User scale, index 0x80B0:01, 0x80B0:11, 0x80B0:12

The user scale is disabled in the factory setting. It can be enabled via
index 0x80B0:01 "Enable user scale".

Parameterization is carried out via the indices:
0x80B0:11 (offset user scale and 0x80B0:12 (gain user scale).

Correction calculation

The terminal continuously accepts the setpoints from the EtherCAT process data, converts them according to the settings and passes them on to the internal DAC (digital-analog converter), which forms the electrical output signal (see Data stream).

Calibration / scaling	Status	Conversion	Meaning
User scale (user calibration)	active: 0x80B0:01 = TRUE	Y_SC= Y_S1x A_Sx 2^-16+ B_S	Y_SC: Value after user scale Y_S1: Value before user scale A_S: Gain user scale (0x80B0:12) B_S: Offset user scale (0x80B0:11)
User scale (user calibration)	Disabled (default): 0x80B0:01 = FALSE	Y_SC = Y_S1
Vendor calibration	active (default): 0x80B0:08 = TRUE	X_DAC= Y_SCx A_H x 2^-16 + B_H	X_DAC: Output value with active vendor calibration with: B_H: Offset vendor calibration (0x80BF:01) A_H: Gain vendor calibration (0x80BF:02)
User calibration	active: 0x80A0:07 = TRUE	X_DAC= Y_SC x A_A x 2^-20 + B_A	X_DAC: Output value with active user calibration with: B_A: Offset user calibration (0x80B0:15) A_A: Gain user calibration (0x80B0:16)
No calibration	0x80B0:01 = FALSE, 0x80B0:08 = FALSE, 0x80A0:07 = FALSE	X_DAC= Y_SC	X_DAC: Output value if vendor and user calibration are disabled.
