Interval Period of calibration:
Perform self-calibration to verify that your instrument is operating properly. Self User’s calibration performs an internal self-alignment routine to optimize the signal path in the oscilloscope. The routine uses internally generated signals to optimize circuits that affect channel sensitivity, offset and trigger parameters. Let the instrument warm up for at least 30 minutes before performing self-calibration. You should perform self-calibration according to the following recommendations:
- Every 12 months or after 2000 hours of operation
- If the ambient temperature is > 50 °F from the calibration temperature
- If you want to maximize the measurement accuracy
- After experiencing abnormal operation
- To verify proper operation after repairing
