16.4.3 Time Base Calibration
Time base calibration is used to adjust the time base inside the device to its most accurate state.
This calibration requires the use of an external 10 MHz standard frequency source. The
connection relationship is shown in the figure below. Connect the 10 MHz output of the frequency
source to the frequency meter input of the device:

After configuring the calibration environment according to the above figure, ensure that the
standard frequency source and the heat engine time of the device exceed the specified minimum
time, execute Utility > Test/Cal > TimeBase Cal to enter the relevant setting page.
