• Setting range of measured and correction values when using revise values
A1 < A2 ≤ A3 ≤ ... ≤ A16
(A1 + B1) < (A2 + B2) < (A3 + B3) < ... < (A16 + B16)
A and B are within the measurable range or scaling range of the range type*
* Within the scaling range: –5% to 105% of the scale value or –20000 to 30000 (the decimal
place is the same as the setting for the scale value)
• Setting range of measured and correction values when using absolute values
A1 < A2 ≤ A3 ≤ ... ≤ A16
B1 < B2 < B3 < ... < B16
A and B are within the measurable range or scaling range of the range type*
* Within the scaling range: –5% to 105% of the scale value or –20000 to 30000 (the decimal
place is the same as the setting for the scale value)
Note
• Make sure that the leftmost value is less than the rightmost value for span and scale.
• Calibration correction cannot be set on ON/OFF input (DI), delta computation, and square
root computation channels. In addition, calibration correction cannot be used on all channels
if the bias function is enabled.
Setting the calibration correction function: Section 7.23
