Warning:
To prevent electric shock or fire, use a suitable power adapter. Only power adapters that are dedicated to this product and approved for use in the country of use may be used.
Warning:
The two channels of the oscilloscope are non-isolated channels. Note that the channel should use a common reference when measuring, and the ground wires of the two probes cannot be connected to two non-isolated places with different DC electrical levels, otherwise it may cause a short circuit due to the ground wire connection of the oscilloscope probe.
Warning:
Note that the channel should use a common reference when measuring, otherwise it may cause a short circuit due to the ground wire connection of the oscilloscope probe.

When the oscilloscope is AC powered by adapter or connected with AC
4
powered computer through the port, it is not allowed to measure the primary power supply of power grid.
Warning:
If the input port of the oscilloscope is connected to a voltage with a peak value higher than 42V (30vrms) or a circuit with a peak value of more than 4800 VA, the following measures shall be taken to avoid electric shock or fire:
Only voltage probes, test wires and adapters with proper insulation attached to the oscilloscope or accessories suitable for oscilloscope instrument series products specified by our company shall be used.
Before use, check the multimeter test probe, oscilloscope probe and accessories for mechanical damage. If damage available, replace it.
Remove all unused multimeter test probes, oscilloscope probes and accessories (power adapter, USB, etc.).
Firstly, plug the power adapter into the AC socket, and then connect it to the oscilloscope.
When testing in a CAT II environment, do not connect a voltage higher than 400 V to any input port.
When testing in a CAT II environment, do not connect a voltage with a voltage difference of more than 400 V to the isolated input port.
Do not use an input voltage higher than the rated value of the instrument. Pay special attention when using 1:1 test wires, because the probe voltage will be directly transmitted to the oscilloscope.
Do not touch the bare metal BNC or banana plug.
Do not insert metal objects into the connector.
Use the oscilloscope only in the specified way.
The voltage rating mentioned in the "warning" information is the limited value of "working voltage". They represent V ac rms (50-60 Hz) in AC sine wave applications; and V dc in DC applications. CAT is the prefix, and II
5
refers to the level. Level II is the low voltage and high energy level, which refers to the local electrical level applicable to electrical appliances and portable equipment.
Only a qualified person should perform internal maintenance.
Check all Terminal Ratings. To avoid fire or shock hazard, check all ratings and markings on this product. Refer to the user manual for more information about ratings before connecting to the instrument.
Do not operate without covers. Do not operate the instrument with covers or panels removed.
Avoid exposed circuit. Be careful when working on exposed circuitry to avoid risk of electric shock or other injury.
Do not operate if any damage. If you suspect damage to the instrument, have it inspected by qualified service personnel before further use.
Do not operate in damp conditions.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry.
Using the equipment not in accordance with the method specified by the manufacturer may damage the protection provided by the equipment.
2. 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:
1.Check whether there is any damage caused by transportation.
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.
2.Check the Accessories
The supplied accessories have been already described in the "Appendix A: List of Accessories" of this Manual. You can check whether there is any loss of accessories with reference to this description. If it is found that there is any accessory lost or damaged, please get in touch with our distributor responsible for this service or our local offices.
3. Check the Complete Instrument
If it is found that there is damage to the appearance of the instrument, or the
6
instrument can not work normally, or fails in the performance test, please get in touch with our distributor responsible for this business or our local offices. If there is damage to the instrument caused by the transportation, please keep the package. With the transportation department or our distributor responsible for this business informed about it, a repairing or replacement of the instrument will be arranged by us.
