Where
spanO
E
is the calculated output error (percent of span) for a cali-
bration point.
O
is the measured output for a calibration point.
ideal
O
is the theoretical output value at a calibration point.
fs
O
is the theoretical output value at Output 100% (full scale).
zero
O
is the theoretical output value at Output 0%.
Absolute (output unit):
idealabsO
OOE −=
Where
absO
E
is the calculated absolute output error for a calibration
point.
Other terms are similar to Percent of Output Span equation.
Absolute (input unit):
IIE
idealabsI
−=
Where
absI
E
is the calculated absolute input error for a calibration
point.
ideal
I
is the measured output value projected (using the trans-
fer function equation) to input, i.e. the input value that
theoretically produces the measured output value.
I
is the measured input for a calibration point.
