How to Use
Display and Controls
Connections
Power Supply:
Connect 9V DC power supply to the 5.5x2.1mm
jack at bottom (center positive). Power supply
voltage must be in the range of 8 - 10V.
Probe:
Connect probe to the BNC connector at top.
Power supply voltage must not exceed
10V. Otherwise it may damage the ICs
inside.
Attention
1.
Allowed maximum signal input voltage
is 50Vpk (100Vpp) with the clip probe.
2.
Operations
[V/DIV]:
Select sensitivity or vertical position. The selected parameter indicator will be highlighted.
[SEC/DIV]:
Adjust the parameter seleted (highlighted). Short press toggles
mode.
Fast Adjustment
[TRIGGER]:
Enter HOLD state (freeze waveform). Press it again will de-freeze.
Couple switch:
Set couple to DC, AC, or GND. When GND is selected the scope input is isolated from input
signal and connected to ground (0V input).

firmware version
-055 or later)
About Trigger State
The trigger can have three states including Holdoff, Waiting, and Trigged. They are explained below.
Holdoff:
Waiting:
Trigged:
Trigger is disabled until a portion of sample buffer prior to a trigger point is filled with raw data.
Trigger is waiting for a valid signal slope.
A valid signal slope has been detected and registered.
Rolling Mode
When timebase is set to 50ms or slower and trigger mode is set to AUTO the scope will automatically switch to
where waveform shifts from right to left constantly. The trigger is disabled under this mode.
Rolling Mode
Fast Adjustment
Short press of [ADJ] toggles
mode on and off for VPos, HPos, and
Trigger Level. A
