4. Press F1 (V/F cursor), cursor measurement turns to voltage amplitude from frequency (cycle).
Up and down cursor appears on the screen at the moment.
5. If use needs to move the cursor, press “
”, one time for one space, press this key for
more than 1 second for fast move, the cursor moves continuously in the same direction.
6.Press "MODE" to switch up/down cursor, lighter one indicates state of activation
Manual cursor measurement- increment for horizontal
or vertical coordinate figure and increment between two
cursors
•Time cursor: time cursor displays as vertical line on
the screen, which can measure ver tical parameter,
result appears on the bottom of screen, see picture
2-11-2.
•Voltage 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.
In order to clearly observe some serial signals, as UART, IIC, record mode can be used.
Press "REC", the device captures and records signals, after the records, result displays on the
screen by page order.
•Press "NEXT", turn to next page, 10 pages can be continuously turned.
•Press "PREVIOUS", turn back to the previous page.
•State of movement and measurement of cursor is same as "HOLD".
Digital Oscilloscope memorizes 10 series waveforms to its internal memorizer. The memorized
date can be stored for 10 years, memorizer space can be repeatedly used for one million times.
The waveform data in it can be recalled back to current oscilloscope, or be sent to upper computer
by its internal Bluetooth, as portable computer or PC, then be opened by relevant software in
computer. Measurement in computer may also be taken.
