2. When the cursor is located at "CH_A" or "CH_B", long press "■" button to enter calibration status.
3. Press "●" button to "save the current setup parameters" »
4. Scroll "- ... +" left and right to select different options of "Index".
5. Scroll "- ... +" downward to select different options of "Detail".
6. Scroll "<...>" left and right to choose different options of "Item".
7. Scroll "<...>" downward to select different options of both categories of "Waveform Display Settings" and "Waveform Measurement Settings".
8. When the cursor is located at "SAVE" or "LOAD", press "▲" key to perform file operation
In calibration state,
9. The reference voltmeter parallels the input of the oscilloscope probe.
10. The first line on the screen displays the calibration message.
11. Scroll "- ... +" left and right to adjust the calibration readings (referring to the reference voltmeter readings).
12. Scroll "<...>" left and right to select different calibration gears.
13. Scroll "<...>" downward to select different calibration parameter options.
14. When the cursor is located at the bottom line, scroll "- ... +" left and right to choose different ways to exit calibration.
15. When the cursor is located at the bottom line, press "■" button to exit the calibration status and return to working status.
In working state,
16. The colors of both item columns of "TRIGG" and "YPOS" indicates the corresponding channels "A, B, C, D"
17. All colors of "measurement parameters" columns indicate the corresponding channel "A, B, C, D, common"
18. "B.L" column indicates the screen backlight control. Scroll "- ... +" button left and right to adjust.
19. "Vol" column indicates the buzzer volume control. Scroll "- ... +" button left and right to adjust.
In "TRIGG" column,
20. "> Vt" and "<Vt" indicate trigger operation when measured signal is greater or less than the trigger level Vt valueof that channel.
21. "> TH" and "<TH" indicate trigger operation when signal’s high level pulse width is greater or less than the cursor value of ⊿ T = T1-T2.
22. "> TL" and "<TL" indicate trigger operation when signal’s low level pulse width is greater or less than the cursor value of ⊿ T = T1-T2.
23. In working state, if no operational instructions are given within 600 seconds (10 minutes), the system will automatically enter power-saving state, and the green indicator will light up.
24 In power-saving state, press any key, and the system will automatically return to working state, with the green indicator off.

Wondering if you could write more-detailed instructions. I don’t know how to use some functions. -------------------------------------------------------------------------------------------------------------------------------------------------------- Posted 2012:06:04 22:01:32 Author sbmtv

Hey, OP. I wonder if the the funtions for channel C and D haven’t been built up. And I have seen your schematics, the C and D channels seem unable to fit into different level standards. However, the A and B analog channels are good, if you improve the software processing, it will be a nice product. Keep going, everyone will love it.
