Precautions
1)
Do not use a supply voltage higher than the specified maximum input voltage of
9-12VDC to the instrument, as this may damage it and also invalidate your
warranty.
2)
Do not attempt to directly measure mains power supply without using a step down
transformer. DO NOT EXCEED 50V MAX

Panel Description
The photo above shows the screen and various front panel controls. They are explained
respectively below.
Screen
1)
Vertical position indicator – the small triangle on the left border of the grid– indicates the 0 volt input
level. Its position can be changed up or down, by pressing [VPOS] and turning the adjustment knob.
2)
Trigger level indicator – the small triangle on the right border of the grid – shows the threshold
voltage of trigger. It is triggered when the input signal level crosses the threshold voltage level; the
trigger level is referenced to the input signal ground.
3)
Window position indicator – indicates the displayed portion of sampled memory. The distance
between the two short vertical bars at the bottom represents the whole length of sampled memory,
which is usually much longer than the screen can display. So at any given moment the screen can only
display a portion of the sampled data. The window position indicator shows which portion is being

- Page 4 At using 10X probe remember to multiply vertical reading by 10 for true results. If, for example, the displayed signal amplitude is 2.5V the real signal amplitude is actually 25V. (a) Under compensation (b) Right compensation (c) Over compensation Fig 6 JYE Tech - 4 - www.jyetech.com...
- Page 5 Time-base, then you should carry out zeroing for that Time-base. Rolling Display Mode When Time-base is set to 0.1s/Div or slower DSO 082 uses a display mode called “Rolling”. In this mode the trace shifts from right to left, simulating time passing.
- Page 6 For Windows users, the PC application is “avrubd.exe” from Shao Ziyang (http://blog.ednchina.com/shaoziyang/). Please download this program from JYE Tech web site and copy it to your computer (no installation required). Refer to the document “How to Program the Scope” for more detailed operation procedures.
- Page 7 The programming header for ATmega64 (U2) is J3. Its pin-out is shown Fig 12 and is also indicated on the PCB. If JYE Tech’s USB AVR Programmer (PN: 07302) is used to program the Fig 12 J3 pin-out oscilloscope remember to connect programming ribbon cable to header J5 on 07302 board.
- Page 8 All replaced parts and oscilloscopes for which a refund has been given shall become the property of JYE Tech Ltd. This limited warranty applies only to the hardware components of the oscilloscope that have not been subjected to: accident, misuse, neglect, fire or other external causes, alternations, repair, or commercial use.
