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.
Probe Compensation
Perform this function to match the characteristics of the probe and the channel input. This
should be performed whenever attaching a probe to any input channel at the first time.
■From the “Probe” menu, select attenuation to 1:10. Set the switch to “X10” on the probe and
connect it to CH1 of the oscilloscope. When using the probe hook-tip, insert the tip onto the probe
firmly to ensure a proper connection.
■Attach the probe tip to the Probe Compensator and the reference lead to the ground
connector, select CH1, and then press the “AUTOSET”button into the menu or the toolbar.
■Check the shape of the displayed waveform.
Correctly Compensated
Over Compensated
USER’S MANUAL 11

Getting Start
Under Compensated
1. If necessary, use a non-metallic tool to adjust the trimmer capacitor of the probe for the fattest
square wave being displayed on the oscilloscope.
2. Repeat if necessary.
WARNNING: To avoid electric shock while using the probe, be sure the perfection of the insulated
cable, and do not touch the metallic portions of the probe head while it is connected with a voltage
source.
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 other
A-Type Plug of USB cable to oscilloscope USB port.
■Input a signal to a channel of the oscilloscope
The oscilloscope is equipped with two channels plus external trigger.
Please input signal in the following steps:
1. Set the attenuation switch on the probe as 10X and connect the probe on the oscilloscope with
CH1. Aim the slot in the probe connector at the faucet on BNC of CH1 and insert, then, turn right to
lock the probe. Finally, attach the tip of probe and ground nip to the Connector of Probe
compensator.
USER’S MANUAL 12

Getting Start
2. Set the CH1 probe attenuation of the oscilloscope to X10. (The default is X1).
3.Attach the tip of probe and ground nip to the Connector of Probe compensator. Click the
button. A square wave will be displayed within a several seconds. (Approximately 1 kHz, 2V, peak-
to- peak).
4. Inspect CH2 with the same method. Repeat steps 2 and 3.
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 5v 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 “Utility -> Calibration” option and follow the directions on the screen.
The self calibration routine takes about several minutes.
