Symbols used in calibration formulas
The calibration formulas use specific symbols. These symbols define the algorithms that are used in the calibration calculations.
List of the symbols used in calibration formulas
- i
- Input value: nominal or actual.
- i lower
- Input range, lower limit.
- i upper
- Input range, upper limit.
- ia
- Actual input value (as found input).
- icalc
- Calculated input value (input as calculated from the as found output).
- olower
- Output range lower limit.
- oupper
- Output range upper limit.
- oa
- Actual output value (as found output).
- ocalc
- Calculated output value (output as calculated from the input).
- Δi
- Input range span.
- Δo
- Output range span.
- rlower
- Range limit From value (lower limit).
- rupper
- Range limit To value (Upper limit).
- Tolerance
- Tolerance value entered, for example, +/- 2.5, +2.5 or -2.5.
