4.1. How to Implement the Function Inspection
Make a fast function check to verify the normal operation of the instrument. First, connect the
oscilloscope with PC successfully, and then do the following steps:
1. Click in the software interface to restore to factory settings. The default attenuation coefficient
set value of the probe in the software is 10X.
2. Set the Switch in the Oscilloscope Probe as 10X and Connect the Oscilloscope with CH1
Channel.
Align the slot in the probe with the plug in the CH1 connector BNC, and then tighten the probe
with rotating it to the right side.
Connect the probe tip and the ground clamp to the connector of the probe compensator.
3. Click on the right top of the software interface to auto set.
The square wave of 1 KHz frequency and 3.3 peak-peak value will be displayed.
4. Check CH2 by repeating Step 2 and Step 3.
4.2. How to Implement the Probe Compensation
When connect the probe with any input channel for the first time, make this adjustment to match the
probe with the input channel. The probe which is not compensated or presents a compensation
deviation will result in the measuring error or mistake. For adjusting the probe compensation, please
carry out the following steps:
1. Click in the software interface to show the Home menu. Choose "Channel", set the "Probe
Rate" in the menu as 10. Set the switch in the probe as 10X and connect the probe with the CH1
channel. If a probe hook tip is used, ensure that it keeps in close touch with the probe. Connect the
probe tip with the signal connector of the probe compensator and connect the reference wire clamp
with the ground wire connector of the probe connector, and then click
software interface to auto set.
The set values of the probe switch are 1X and 10X
