Window for more details). Note that offset calibration should be performed before gain calibration to en-
sure accurate results. Refer to the CS5534 datasheet for more details.
Figure 7. CDB5534U Calibration Window
Self Offset or Gain Calibrations:
1) Pull down the Self Offset or Self Gain box, and select the setup number you want to use to cali-
brate the channel.
2) The offset and gain register values will automatically update when the calibration is completed.
System Offset Calibrations:
1) Attach a grounded input to the physical channel you want to calibrate. Note that the grounded input
must be within the common mode range of the particular amplifier (1X-64X) for proper operation.
2) Pull down the System Offset box, and select the setup number you want to use to calibrate the
channel.
3) When the calibration is complete, the screen will automatically update the offset and gain registers
with the new values.
System Gain Calibrations:
1) Attach a full-scale input to the physical channel you want to calibrate.
2) Pull down the System Gain box, and select the setup number you want to use to calibrate the
channel.
3) When the calibration is complete, the screen will automatically update the offset and gain registers
with the new values.
