1. Safety Precautions

This product complies with the requirements of the following European Community Directives: 2004/108/EG

(Electromagnetic Compatibility) and 2006/95/EG (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.

* 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.

-91-

* 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.

3.1. Introduction to the Structure of the Oscilloscope

When you get a new-type oscilloscope, you should get acquainted with its front panel at first and this digital

storage oscilloscope is no exception. 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.

3.1. Front panel

This oscilloscope offers a simple front panel with distinct functions to users for their completing some basic

operations, in which the knobs and function pushbuttons are included. The knobs have the functions similar to

other oscilloscopes. The 5 buttons (F1 ~ F5) in the column on the right side of the display screen or in the row

under the display screen (H1 ~ H5) are menu selection buttons, through which, you can set the different

options for the current menu. The other pushbuttons are function buttons, through which, you can enter

different function menus or obtain a specific function application directly.

4. How to implement the General Inspection

After you get a new oscilloscope, it is recommended that you should make a check on the instrument

according to the following steps:

If it is found that the packaging carton or the foamed plastic protection cushion has suffered serious

damage, do not throw it away first till the complete device and its accessories succeed in the electrical

and mechanical property tests.
