To Perform Self-Calibration
✔
Perform self- calibration to verify that your instrument is operating
properly. Self- 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 to 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 > 10 °C from the calibration
temperature
•
If you want to maximize the measurement accuracy
•
after experiencing abnormal operation.
•
to verify proper operation after repairing.
