ΔT Cursors
△T cursors can be turned on or off by entering Menu and touch
the button “△T”. When the cursors are on the time difference
between the two cursors is displayed at the screen top-left
corner. This readout changes as cursor position changes.
To change cursor position first select the cursor you want to
move by touching it so as it is highlighted. Then touch any
where in screen and scroll horizontally. You should see the
selected cursor shifts. De-select the cursor by touching it again
or by selecting the other cursor.
Please note that the unit for △T readout is the same as that of
current timebase.
ΔV Cursors
△V cursors can be turned on or off by entering Menu and
touch the button “△V”. When the cursors are on the voltage
difference between the two cursors is displayed at the screen
top-left corner. This readout changes as cursor position
changes.
To change cursor position first select the cursor you want to
move by touching it so as it is highlighted. Then touch any
where in screen and scroll vertically. You should see the
selected cursor shifts. De-select the cursor by touching it again
or by selecting the other cursor.
Please note that the unit for △V readout is the same as that of
current sensitivity.
Frequency
Measurement
Frequency measurement can be turned on or off by entering
Menu and touch the button “Freq”. Frequency readout is
displayed at the screen lower-right corner. Please note that
frequency measurement is disabled when timebase is set to
50ms/Div or slower because it will cause waveform sampling
error due to limited MCU capability.
Voltage
Measurements
Voltage measurements can be turned on or off by entering
Menu and touch the button “V”. Voltage measurements include
Vmax, Vmin, Vpp, Vavr, and Vrms (true RMS) of captured
waveform. The readouts are displayed at the screen lower-left
corner. Please note that voltage measurements are disabled
when timebase is set to 50ms/Div or slower because it will
cause waveform sampling error due to limited MCU capability.
Change Auto-off Time
To change auto power-off time enter Menu and touch
“More>>” at screen top-right corner and then touch the button
“Auto Off”. This brings up the “Auto Power-off Time” screen.
Auto power-off time can be set to 2, 5, 15, 30, 60 minutes or
Never. If there is no screen touch activity detected within the
time period the oscilloscope will shut down itself. However, if
external power supply (USB) is used the auto power-off timing
is disabled. The unit will never shut down itself in this case.
