I-channel: This tab changes the sign and the magnitude of the offset and the full scale range settings.
Figure 12: I-Channel Panel
• 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 an 8 bit (0 to 255) 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 560mV to a maximum of 840mV. The default setting is 700mV.
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.
