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.
1 Press button to access Utility mode at F4 softkey.
2 On page 3/4 of Utility mode, press F1 to start self- calibration.
3 A self- calibration dialog box appears to alert user to remove all input
connections to the instrument before pressing F1 to start
self- calibration.
Disconnect all probe and meter connections to the input terminal of the instrument.
Allow the instrument to warm up at least 30 minutes before performing
self-calibration. Refer to “Self-Calibration 150” for more information.
