Voltage measure marker V1 and V2 (Dot, vertical) – A voltage measure value between
V1-V2 could be displayed.
Time measure marker A and B (Dot line, horizontal) – A time measure value between A
and B could be displayed.
Y positions marker (Purple) – Y position center line for adjustment reference
Trigger level marker (Yellow) – Used to set trigger level

Sync. Mode: When blinking, press ▲ and ▼ to select 4 different synchronization
mode: AUTO, NORM, SING, and NONE.
AUTO – Automatic synchronous sweeping mode, displays waveform even not
triggered.
NORM – Normal synchronous sweeping mode, displays whenever trigged.
SING- Single sweeping mode, display when triggered, then stopped with latest
triggered waveform.
NONE – Random sampling mode
SCAN – Scan mode, to check long period low frequency signal.
Vertical Scale: When blinking, press ▲ and ▼ to select different level of sensitivity.
Total 19 scales are optional from 10mV/Div to 100V/Div. Note 1: If you use scale above
20V/Div, please use probe with attenuation of 10:1). Note 2: If newly set scale does not
match reference waveform, the latter will be cleared.
Horizontal sensitivity: When blinking, press ▲ and
▼
to select different sensitivities. ,
from 1uS/Div to 10S/Div total 22 grades. Note 2: If newly set sensitivity does not match
reference waveform, the latter will be cleared.
Y position: When blinking, press ▲ and
▼
to adjust the vertical position of the
waveform. Press M to hide/activate Y position marker if needed.
Calculation Mode: Auto calculation modes include:
FREQN – Signal frequency
CYCLE – Signal period
DUTY – Duty time
Vpp – AC signal peak-peak value
Vram – AC signal effective value
Vavg – AC signal average value
DC.V – DC signal average value.
Power supply mode: Power supply by internal battery or USB port. Battery bar will be
displayed when powered from internal.
