I-channel: This tab changes the sign and the magnitude of the offset and the full scale range

settings.

• I-channel Offset Sign – This pull-down selects a positive or negative offset.

• I-ch Offset – This slider selects the magnitude of I-ch Offset applied. Adjustment can be

done using the computer mouse/pointer, or using left/right arrow keys once the slider

has been selected. Although the offset is entered in a 10 bit (0 to 4095) relative form, it is

also displayed in approximate mV.

•

I-Channel Full Scale - The approximate I-Channel input full scale range (mV peak-to-

peak) is selected, ranging from a minimum of 600mV to a maximum of 1000mV. The

default setting is 800mV.

Note: No changes will take effect until the Write I-ch Reg button is clicked. Also, the ADC must

be re-calibrated if the full-scale is changed.
