waveform of each channel. If the offset is greater than 0.5 div, check whether there
are interference signals around you and whether the power source is well
grounded. After that, perform self-calibration again.

4.2 Test Result Record
Record and keep the test result of each test. In the last chapter of this manual, a test
result record form is provided. The form lists all the test items and their
corresponding performance limits as well as spaces for users to record the test
results.
TIP
It is recommended that users photocopy the test record form before each test and record the
test results in the copy so that the form can be used repeatedly.
