Calibrating the Analog Output Subsystem
This section describes how to use the KUSB-3100 Calibration Utility
to calibrate the analog output subsystem of a KUSB-3100 module.
To calibrate the analog output circuitry, you need to connect an
external precision voltmeter to analog output channels 0 and 1 of the
KUSB-3100 module.
Perform the following steps to calibrate the analog output circuitry:
1. Select the D/A Configuration tab of the KUSB-3100 Calibration
Utility.
2. Connect an external precision voltmeter to Analog Output 0
(DAC Ch0) of the KUSB-3100 module.
3. Adjust the offset by entering values between 0 and 63 in the DAC
0 Offset edit box or by clicking the up/down buttons until the
voltmeter reads 0 V.
4. Connect an external precision voltmeter to Analog Output 1
(DAC Ch1) of the KUSB-3100 module.
5. Adjust the offset by entering values between 0 and 63 in the
DAC 1 Offset edit box or by clicking the up/down buttons until
the voltmeter reads 0 V.
Note: At any time, you can click Restore Factory Settings to reset
the D/A calibration values to their original factory settings. This
process will undo any D/A calibration settings.
Once you have finished this procedure, the analog output circuitry is
calibrated. To close the KUSB-3100 Calibration Utility, click the close
box in the upper, right corner of the window.
