Basic Operations
1. Before first-time use
Close the internal battery switch (see Fig.2) by sliding
●
it towards the USB connector with a small stick.
Charge battery for more than 10 hours by connecting
●
the scope to a USB power.
2. Power On/Off
Power-on Short press [P] button will turn DSO112 on.
●
Power-off There are three ways to turn the unit off.
●
1 ) Enter Menu and touch
button.
Pwr Off
2 ) Hold [P] button for about 3 seconds under Running
Pwr Off
or Hold state.
3 ) Hold [P] button for about 15 seconds under any state.
3. Connecting to signal to be viewed
To view a signal first connect the black clip to the reference ponit (ground) of circuit under test.
●
Then connect the red clip to the signal of interest.
Auto Power Off
Oscilloscope will automatically shut down if running on battery and no touch activity for certain
period of time. The factory default setting for this time is 2 min. It can be changed by entering
Menu->More and touching AutoOff button.

Functions
Align VPos indicator to 0V trace.
Save captured waveform data to internal EEPROM. The
most recently captured data will be saved no matter this
function is executed in Running state or Hold state.
Recall saved waveform data from EEPROM. The
parameters used for the data will also be recalled.
Send waveform data via serial connection (virtual COM
port on USB). The most recently captured data will be
sent.
Restore factory default settings for various parameters
(except AutoOff time).
Save or load preset scope parameters.
Bring up dashboard for quick preset access.
Turn cursor

On/Off.
Turn voltage read-outs On/Off. The unit of voltage read-
out is the same as unit of vertical sensitivity.
Turn frequency read-out On/Off.
Bring up "Test Signal Frequency" screen where test
signal frequency can be changed.
Bring up "Auto Power-off Time" screen where auto
power-off time can be selected.

Remarks
The existing data in EEPROM will be over-written.
Recalled waveform is always displayed in Hold state.
Waveform data are sent in CSV file format. XModem
protocol is used for the transfer. USB driver for CP2102
is required (refer to the section "USB Connection" ).
Press [P] button at Setup screen will also perform the
same function.
Navigate with "<<" and ">>" buttons. Touch a row to
highlight it and use "Save" or "Load" button to execute.
Display Vmax, Vmin, Vpp, Vavr, and Vrms on screen.
Not function when timebase is set to 50ms/div or slower.
