Install Software

Caution: You must install the software before using the oscilloscope.

  1. While in Windows, insert the installation CD into the CD-ROM drive.
  2. The installation should start up automatically. Otherwise in Windows Explorer, switch to the CD-ROM drive and run Setup.exe.
  3. The software Installation is started. Click ‘Next’ to continue.
  4. Choose a destination directory. Click ‘Next’ to continue.

2. Connect the B-Type Plug of USB cable to the product USB port.

  1. New hardware is found.
  2. Select the specific location.
  3. New hardware search wizard starts to search the driver.
  4. New hardware wizard installs the product.
  5. The wizard has finished installing.

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.

  • If necessary, use a non-metallic tool to adjust the trimmer capacitor of the probe for the flattest square wave being displayed on the oscilloscope.
  • Repeat if necessary.


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 con-nected with a voltage source.

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 B-Type Plug of USB cable to oscilloscope USB port.

Input a signal to a channel of the oscilloscope

The oscilloscope is equipped with four channels plus external trigger.

Please input signal in the following steps:

  • 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.

  1. Set the CH1 probe attenuation of the oscilloscope to X10. (The default is X1).
  2. 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).
  3. Inspect CH2 ,CH3 and CH4 with the same method. Repeat steps 2 and 3.

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 V 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.
