Left-aligned presentation
The extended measuring range cannot be used in left-aligned mode.
In this case the Autorange function operates without the 10% measuring range extension.
Note
This combination is not permitted.
INT value
The measured value is displayed based on the set presentation.
Presentation Meaning
0: left-aligned 31 bit+sign, end value:0x7FFFFF00 (extended
measuring range cannot be used)
1: right aligned 24 bit+sign, end value:0x7FFFFF
2: scaled 1 bit / µΩ Measured value in µΩ (upper limit at 2.147 kΩ)
3: scaled 1 bit / mΩ Measured value in mΩ (upper limit at 2.147 MΩ, not
recommended for measuring ranges below 10 Ω)
4: scaled 1 bit / Ω Measured value in Ω (not recommended for
measuring ranges below 10 kΩ)
5: as REAL value The calculated REAL value is entered instead of the
INT value.
Table 3: Presentation
Only the REAL representation covers the whole measuring range including the measuring range with
uniform accuracy.
REAL value
The following equation is used for calculating the REAL value from the value that has already been offset
against the manufacturer and user values (F
