Presentation
Presentation, index 0x8000:1D [} 155]
The presentation of the values in the process data can be changed:
Value Designation
0
"left aligned"
1
"right aligned"
2
"scaled"
Table 4: Presentation of the measured value
Scaled presentation is set as default.
Factors are taken into account, extended measuring range
Only in scaled view the factors 0.1/1/10/100 are taken into account between the measuring ranges.
In left aligned view the extended measuring range is not available.
5.5.7
Zero Compensation Interval
Zero Compensation Interval (Index 0x8000:19 [} 155])
Zero Compensation Interval and 50 Hz mode
In 50 Hz mode this function should not be used (0: off).
The compensation function compensates the internal offset drift of the ADC. The interval length is selectable.
If setting 4 "Triggered by PDO" is used, the time for reading the internal offset can be selected manually via
the "Start Calibration" process data bit (index 0x7000:02) [} 159].
5.5.8
Calibration
Calibration (indices 0x8002 [} 157] and 0x800F [} 157])
The terminal features manufacturer and user calibration options, which can be switched on and off
independently. The calibration always applies to all measuring ranges. Adaptation in 60 Hz mode and
compensation of the AC system offset cannot be switched off.

Meaning
Left-aligned presentation:
full scale value corresponds to 0x7FFFE000 (0x7FFFFFFF) or 0x80000000
Right-aligned presentation: 18-bit resolution of the measuring range,
full scale value corresponds to 0x0003FFFF (262143
(-262144
).
dec
In the extended measuring range these limits are exceeded!
Scaled presentation:
corresponds to 1 bit per µV / µA,
Examples:
Mode 0, Autorange, 2.5 V: 2,500,000 decimal
Mode 2, 800 mA: 800,000 decimal
Version: 3.0
