•
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.
