DAC488 User’s Manual DAC488 Calibration 49
Part III: Automatic Calibration Report
After the automatic calibration finishes, a calibration report will be printed if the DAC488 is connected to
an IEEE printer. The following example shows the calibration report of the three volt ranges for Port 1:

Automatic Calibration Report Format
A report similar to the one above will be printed for all four ports. A description of each item in the auto-
calibration report is given below:
•
Nominal: The voltage the DAC was programmed to output.
•
Actual: The actual voltage measured by the DMM.
•
Error: The difference between the Nominal and the Actual values.
•
Result: Indicates Pass if the port is functioning within the stated specifications.
