Setup Conditions of Measured and Correction Values
• 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.
