1. Safety Precautions
This product complies with the requirements of the following European Community Directives:
2014/30/EU (Electromagnetic Compatibility) and 2014/35/EU (Low Voltage) as amended by
2004/22/EG (CE-Marking). Overvoltage category II; pollution degree 2.
To ensure safe operation of the equipment and eliminate the danger of serious injury due to
short-circuits (arcing), the following safety precautions must be observed. Damages resulting from
failure to observe these safety precautions are exempt from any legal claims whatever.
* Do not use this instrument for high-energy industrial installation measurement.
* Do not place the equipment on damp or wet surfaces.
* Do not exceed the maximum permissible input ratings (danger of serious injury and/or
destruction of the equipment).
* The meter is designed to withstand the stated max voltages. If it is not possible to exclude
without that impulses, transients, disturbance or for other reasons, these voltages are exceeded
a suitable presale (10:1) must be used.
* Disconnect test leads or probe from the measuring circuit before switching modes or functions.
* Check test leads and probes for faulty insulation or bare wires before connection to the
equipment.
* To avoid electric shock, do not operate this product in wet or damp conditions.
* Conduct measuring works only in dry clothing and rubber shoes, i. e. on isolating mats.
* Never touch the tips of the test leads or probe.
* Comply with the warning labels and other info on the equipment.
* The measurement instrument is not to be to operated unattended.
* Do not subject the equipment to direct sunlight or extreme temperatures, humidity or dampness.
* Do not subject the equipment to shocks or strong vibrations.
* Do not operate the equipment near strong magnetic fields (motors, transformers etc.).
* Keep hot soldering irons or guns away from the equipment.

4
* Allow the equipment to stabilize at room temperature before taking up measurement (important
for exact measurements).
* Do not input values over the maximum range of each measurement to avoid damages of the
instrument.
* Periodically wipe the cabinet with a damp cloth and mid detergent. Do not use abrasives or
solvents.
* The meter is suitable for indoor use only
* Warning:
To avoid fire or electrical shock, when the oscilloscope input signal connected is more than 42V
peak (30Vrms) or on circuits of more than 4800VA, please take note of below items:
- Only use accessory insulated voltage probes and test lead.
- Check the accessories such as probe before use and replace it if there are any damages.
- Remove probes, test leads and other accessories immediately after use.
- Remove USB cable which connects oscilloscope and computer.
- Do not apply input voltages above the rating of the instrument because the probe tip voltage
will directly transmit to the oscilloscope. Use with caution when the probe is set as 1:1.
- Do not use exposed metal BNC or banana plug connectors.
- Do not insert metal objects into connectors.
* Do not store the meter in a place of explosive, inflammable substances.
* Do not modify the equipment in any way
* Do not place the equipment face-down on any table or work bench to prevent damaging the
controls at the front.
* Opening the equipment and service –and repair work must only be performed by qualified
service personal
* Measuring instruments don’t belong to children hands.
Cleaning the cabinet
Prior to cleaning the cabinet, withdraw the mains plug from the power outlet.
Clean only with a damp, soft cloth and a commercially available mild household cleanser. Ensure
that no water gets inside the equipment to prevent possible shorts and damage to the equipment.

To Avoid body damage and prevent product and connected equipment damage, carefully read the
following safety information before using the test tool. This product can only be used in the
specified applications.
Warning:
The two channels of the oscilloscope are not electrically isolated. The channels should
adopt a common ground during measuring. To prevent short circuits, the 2 probe grounds
must not be connected to 2 different non-isolated DC levels.

It is not allowed to measure AC power when the AC powered oscilloscope is connected to
the AC-powered PC through the ports.
Warning:
To avoid fire or electrical shock, when the oscilloscope input signal connected is more than 42V
peak (30Vrms) or on circuits of more than 4800VA, please take note of below items:
Only use accessory insulated voltage probes and test lead.
Check the accessories such as probe before use and replace it if there are any damages.
Remove probes, test leads and other accessories immediately after use.
Remove USB cable which connects oscilloscope and computer.
Do not apply input voltages above the rating of the instrument because the probe tip
voltage will directly transmit to the oscilloscope. Use with caution when the probe is set
as 1:1.
Do not use exposed metal BNC or banana plug connectors.
Do not insert metal objects into connectors.

1. Quick Start
Introduction to the Structure of the Oscilloscope
This chapter makes a simple description of the operation and function of the front panel of the
oscilloscope, enabling you to be familiar with the use of the oscilloscope in the shortest time.
Front Panel
The front panel has knobs and function buttons. The 5 buttons in the column on the right side of the
display screen are menu selection buttons, through which, you can set the different options for the
current menu. The other buttons are function buttons, through which, you can enter different
function menus or obtain a specific function application directly.

4. Probe Compensation: Measurement signal (5V/1kHz) output.
5. Signal Input Channel
6. USB Host port: It is used to transfer data when external USB equipment connects to the
oscilloscope regarded as "host device". For example: Saving the waveform to USB flash disk
needs to use this port.
