Chapter 1:Safe Precautions
The following precautions described herein must be observed during the use of this
instrument. If the instrument is used in a manner not specified in this manual, the
protection provided by the instrument may be impaired. ZHIYUAN Electronics assumes
no liability for the customer’s failure to comply with these requirements.
1.1 General Precautions
In order to avoid injury to operators and damage to the instrument or the devices
connected with the instrument, make sure to comply with the precautions below.
Use correct power cord
Only the dedicated power cord allowed by the country where the instrument is used can
be used. Power cord specifications in mainland: 3×0.75mm2, Ф6.3，IEC 6022753，
L=1500mm. It is used with three-pin plug and has passed CCC certification.
Ground the instrument
The instrument must remain grounded through the protective grounding wire of its
power cord. In order to avoid electric shock, make sure the power cord ground wire is
properly connected with protective earth terminal before connecting any input and
output terminal of the instrument.
Connect probe correctly
The probe’s ground lead is at ground potential. Do not connect it to a high voltage.
Check all ratings before use the instrument
In order to avoid fire and high current impulse, please check all ratings and instructions
of the instrument before use the instrument. For the detail information about all ratings,
please refer to the related user manual.
Use appropriate over voltage protection
In order to avoid the electric shock to operators, make sure an over voltage (such as the
voltage caused by thunderstorm) will not occur.
Do not operate the instrument when the chassis is open
Do not operate the instrument when the chassis is open.
Use the specified power fuse
If the power fuse is necessary to be changed, please return the instrument back to the
factory.The power fuse complied with the specification of this product (Class T,rated
current: 2A, rated voltage: 250V) will be replaced by the maintainer from ZHIYUAN
Electronics.

When the instrument is switched on, do not touch the exposed connections and
components.
Avoid electric shock
Power cord should be inserted into a socket with ground protection on the wall or within
visible area. The socket cannot be used in the overcurrent situation.
When any fault occurs during the use of instrument
When there may be a fault during the use of instrument, please do not remove the
screw of the handle to prevent scratching. If the product has any problem, please stop
operating the instrument immediately and contact ZHIYUAN Electronics in time.
ZHIYUAN Electronics will send engineers to inspect, maintain and adjust it or replace
parts.
Keep instrument ventilated
Inadequate ventilation will cause instrument temperature increase, which may result in
damage to the instrument. Please inspect vent and fan constantly to keep the
instrument ventilated.
Do not use the instrument in a wet environment
In order to avoid the risk of short circuit and electric shock, do not operate the
instrument in a wet environment.
Do not use the instrument in an explosive environment
In order to avoid instrument damage or personal injury, do not operate the instrument in
an explosive environment.
Keep instrument surface clean and dry
To prevent dust or moisture in the air affecting instrument performance, please clean
and dry the surface of instrument.
Electrostatic protection
Static electricity will cause damage to the instrument. The instrument should be tested
in the anti-static area. The internal and external conductors of cables should be
connected to ground to discharge the static electricity before they are connected to the
instrument.
Transportation safety
To avoid damage to the parts (such as keys, knobs or interfaces on the panel) due to
falling of instrument during transportation, please note transportation safety.
The way to use the handle
To ensure the safety of the oscilloscope during use and handling of the oscilloscope,
please follow the method of using the handle.As shown below.

Description
Note
I/O
CAT I
It is applicable to measure
for the circuit not directly
connected with main power
supply
Measured for the circuit which is
not supplied by main power
supply or by main supply
especially with internal protection.
II
CAT II
It is applicable to measure
for circuits directly
connected to the
low-voltage device
Measured for household
appliances, portable tools and
other similar devices.
III
CAT III
It is applicable to measure
for building facilities
Measured for the output socket,
industrial device and other
devices of the distribution board,
circuit breaker and wirings include
cable, busbar wire, junction box,
switch and fixed facilities, such as
those stationary motors
permanently attached to fixed
facilities.
IV
CAT IV
It is applicable to measure
for the terminal of the
low-voltage facilities
Measured for primary over current
protection devices and ripple
control units.
Notes: Note: The CAT I result is measured for the circuit not directly connected with main power
supply. For example, a circuit is not supplied by main power supply or by main supply especially
with internal protection. In the latter case, the transient stress is variable. Therefore, users should
know the tolerant transient stress of device.
WARNING
WARNING symbol indicates serious danger. Improper handling or execution in a
specified process, operation and so on can lead to serious or fatal injury to the users.
Please completely read and fully understand the related notes before continuing
operation.
1.3 Measurement Category

The ZDS2000B Plus Series oscilloscopes are only oscilloscopes are only allowed to be
used in the specified measurement category.
1.4 Instrument Placement
CAUTION
The instrument placement location should meet following conditions:
Do not install the instrument in the place in direct sunlight, near heat sources,
strong magnetic field sources, high voltage equipment or power lines, and where
an excessive amount of soot, steam, dust or corrosive gas is present, and where
there is water, oil or chemical.
The instrument should be placed on a flat, even surface; otherwise the
measurement precision may be impaired.
Good ventilation. In order to ensure good ventilation inside the instrument, there
are cooling holes in real panel to avoid high internal temperature; please make
sure the air inlet and vent of the product keep the air flow freely. When using the
oscilloscope on the work bench, please leave at least 10cm gaps on the top,
back and both sides of instrument.
Protection impairment if used in a manner not specified by the manufacturer.
