1.5 General Check
Please check the instrument as following steps after receiving an oscilloscope:
Check the shipping container for damage:
Keep the damaged shipping container or cushioning material until the contents of the
shipment have been checked for completeness and the instrument has been checked
mechanically and electrically.
Check the accessories:
Accessories supplied with the instrument are listed in "Accessories" in this guide. If
the contents are incomplete or damaged，please notify the franchiser.
Check the instrument:
In case there is any mechanical damage or defect, or the instrument does not operate
properly or fails performance tests, please notify the franchiser.
1.6 Function Check
Perform this functional check to verify that your oscilloscope is operating correctly.
Connect the oscilloscope
You should connect the A-Type Plug of USB cable to your PC USB port and connect
the probe with the signal source.
Input a signal to a channel of the oscilloscope
Please input signal in the following steps:
connect the probe with the signal source and ensure good grounding clip.
User’s Manual 11

1. Attach the tip of probe and ground nip to the Connector of Probe. A square wave
will be displayed within a several seconds. (Approximately 1 kHz, 2V, peak- topeak).
1.7 Self Calibration
The self calibration routine lets you optimize the oscilloscope signal path for maximum
measurement accuracy. You can run the routine at any time but you should always run the
routine if the ambient temperature changes by 5℃ or more. For accurate calibration,
power on the oscilloscope and wait twenty minutes to ensure it is warmed up. To
compensate the signal path, disconnect any probes or cables from the input connectors.
Then, access the “Menu -> Utility -> Calibration” option and follow the directions on the
screen. The self calibration routine takes about several minutes.
1.8 Accessories
All the accessories listed below are standard accessories for the oscilloscope:
