2-12 Display System
2 12 1 Time and Date
•Af ter startup, actual time and date display at the top
lef t corner on the inter face, for mat: mm/dd/yy,
hh/mm/ss (picture 2-10-1).
• The clock is supplied by the back-up
battery inside o f the device, which can wor k for 5 to
10 years, and irrelevant to the Li-ion rechargeable
battery.
•T ake “Operating Instructions F or Oscilloscope” for
reference for the adjustment of clock.
2-12-2 Battery Electric Power Display
•Af ter startup, at the top right corner, display the working
Li-ion rechargeable battery electric power (picture 2-10-2).
•The battery fully charged, 4 cells.
•When 1 cell lef
t, blue color turn to red, warning to
recharge, 30 to 45 minutes may be used by this lef t
power.
•All bars disappear, please recharge promptly , 15 to
20 minutes may be used by this lef t power.
2-13 Measuring System
The oscilloscope displays f orms o f voltage relative to time, and helps user measure and display
wavefor ms. Two ways o f measurements can be adopted: Scale measurement or cursor
measurement.
2-13-1 Scale Measurement
Fast and direct evaluation can be done by this way, f or example, wave f orm amplitude can be
obser ved to judge whether it’s 0.8V or not.
By calculating relevant primary and secondary scale division, then multiplying by proportion
factor , simple measurement can be taken.
F or example, if four main vertical scale divisions between the wavefor m peak and base are
figured out, proportion factor is 200 mV/division, peak value voltage can be calculated by the
following method: 4 divisions * 200mV/div= 0.8V
2-13-2 Movement of Cursor
As the following picture shows, press “HOLD ” or “REC ”, “V/Fcursor ” appear in prompt bar,
indicates function switch button for cursor measurement.
1. Blue vertical cursor appears on the displayed screen, press “ ” to move the cursor, one
time for one space, press this key for more than 1 second for fast move, the cursor moves
continuously in the same direction.
2. P ress “MODE” to switch lef t/right cursor , lighter cursor indicates state of activation.
3. Display mode of frequency and cycle is also switched at the time o f le f t/right cursor switch.
Activate left cursor displays frequency, right cursor for cycle. See picture 2-11-1.

4. Press F1 (V/F cursor) , cursor measurement turns to voltage amplitude f rom f re q uency (cycle).
Up and down cursor appears on the screen at the moment.
5. If use needs to move the cursor , press “ ”, one time f or one space, press this key f or
more than 1 second for fast move, the cursor moves continuousl y in the same direction.
6.P ress "MODE" to switch up/down cursor, lighter one indicates state of activation
.
2-13- Cursor Data Measurement
Manual cursor measurement- increment for horizontal
or vertical coordinate f igure and increment between two
cursors
•Time cursor : time cursor displays as vertical line on
the screen, which can measure vertical parameter,
result appears on the bottom o
f screen, see picture
2-11-2.
•V oltage cursor : voltage cursor displays as horizontal
line on the screen, which can measure vertical parameter,
result appears on the bottom, see picture 2-11-3.
2-14 Waveform Records
In order to clearly observe some serial signals, as U A RT, IIC, record mode can be used.
Press "REC", the device captures and records signals, a f ter the records, result displays on the
screen by page order.
•P ress "NEXT", turn to next page, 10 pages can be continuously turned.
•Press "PREVIOUS", tur n back to the previous page.
•State of movement and measurement of cursor is same as "HOLD".
2-15 Memory System
Digital Oscilloscope memorizes 10 series wave f orms to its internal memori z er. The memori z ed
date can be stored f or 10 years, memori z er space can be repeatedly used f or one million times.
The wave f orm data in it can be recalled back to current oscilloscope, or be sent to upper computer
by its internal Bluetooth, as por table computer or PC, then be opened by relevant sof tware in
computer. Measurement in computer may also be taken.
