Appendix 1 Offset/Gain Adjustment <D300win>
<Offset/gain adjustment>
In this mode, offset value and/or gain value can finely be adjusted for individual channel.
Offset value: Means the lower limit value of the range span. When this value is adjusted, the conversion characteristic curve
moves parallel in vertical direction.
Gain value: Means the upper limit value of the range span. When this value is adjusted, only gain value is changed while
offset value is kept unchanged.
When offset and gain values are changed by scaling, the values that are set by scaling take effect as offset and gain values.
When offset and/or gain values are to be adjusted after scaling, adjust by the values of scaling.
Note 1: Offset/gain adjustable range is within 1% of range span. If adjustment is made using an analog value that exceeds
the adjustable range (if the value is input to a terminal of the module), the value is limited to 1% of range span.
Note 2: If range is changed, offset and gain return to the default values.
Note 3: Offset/gain adjustment is disabled when analog range is set in a batch with the switch provided on the module rear
panel.
