0711-100 Figure 84 Reports View: Scaling Report Values
The Offset parameter value is added to the original value to get rid of a
sign or to get rid of unused value area. For example:
- Air temperature range -50 ... +70 -> offset 50
- Barometric pressure range 600 ... 1100 -> offset -600
The Multiplier value is multiplied by the scale to preserve the decimals
(scale >= 10) or to remove the least significant digits that are not needed
(scale <= 0.1).
Example of BASE32 is as follows:
The temperature value after adding the offset is 72.1242, which is
multiplied by the scale of 10 to preserve one decimal. The integer value
for the conversion is 721.
The value of the Field width text box indicates the field width
(characters or four bit nibbles) for the compressed value. Zeros will be
added in front of the value if the actual length is smaller.
Lizard Setup Software will automatically suggest default values for the
offset and scale of the BASE32 and BCD compressions and for the
fixed length value of the BASE32 compression.
