Gw Instek GDS-2302A 2-channel oscilloscope, Digital Storage oscilloscope, GDS-2302A Data Sheet

The warranty will be void in the event of damage caused by failure to observe these safety instructions! We 

do not assume any liability for any resulting damage!
We shall not accept liability for damage to property or personal injury caused by incorrect handling or non-

compliance with the safety instructions! Any warranty will be void in such cases.
The  unauthorised  conversion  and/or  modification  of  the  product  is  not  allowed  for  safety  and  approval 

reasons (CE).
The design of the product complies with  safety class 1. Use only a domestic mains socket (100 - 240 V~) of 

the public power supply network to power the unit.
The mains socket must be close to the device and easily accessible, or an emergency kill switch device 

must be present.
Measuring devices and devices connected to the power supply should be kept out of the reach of children. 

Therefore, be especially careful when children are around.
First, connect the measurement cable to the oscilloscope; then connect the probe to the signal measuring 

circuit to be tested. After finishing the measurements, first disconnect the measure  ment leads from the 

circuit before you disconnect the cable from the oscilloscope.
Be especially careful when dealing with voltages higher than > 50 V alternating current (AC) or > 75 V direct 

current (DC)! Even at such voltages you can get a life-threatening electric shock if you come into contact 

with live electric wires.
Check the measuring device and its measuring leads for any damage before each measurement. Never take 

any measurements if the protecting insulation is defective (torn, missing etc.).
To avoid electric shock, do not touch the connections/measuring points directly or indirectly during 

measurements.
Never reach beyond the grip surface of the probes during a measurement process. There is danger of a 

life-threatening electric shock.
Do not use the device shortly before, during, or after a thunderstorm (lightning! / high-power surges!). Make 

sure that your hands, shoes, clothing, the floor, the measuring device and/or measuring lines, the circuits 

and its parts are always dry.
Do not use the device in rooms or under unfavourable ambient conditions in which there are or could be 

combustible gases, vapours or dust.
Do not use in the immediate vicinity of:

 - strong magnetic or electromagnetic fields
 - transmitting aerials or HF generators.
 - These can affect the measurement.

Use only measurement lines and accessories for the measurement that match the specifications of the 

oscilloscope.
If a safe operation can no longer be assumed, the device must be put out of operation and secured against 

unintended operation. Safe operation can no longer be assumed if:

 - the device is visibly damaged,
 - the device does not function any more and
 - the device was stored under unfavourable conditions for a long period of time or
 - it has been subjected to considerable stress during transportation.

Never switch the device on immediately after having taken it from a cold to a warm environ  ment. The 

condensation that forms might destroy your device. Allow the device to reach room temperature before 

switching it on.
Never disassemble the product! There is danger of a life-threatening electric shock!
Do not carelessly leave the packaging material lying around, since it could become a dangerous plaything 

for children.
The device is intended only for dry interior rooms (not bathrooms or similar damp rooms). The device must 

not get wet or damp. There is danger of a life-threatening electric shock!
On industrial sites, the accident prevention regulations of the association of the industrial workers’ society for 

electrical equipment and utilities must be followed.
Measurement instruments used at schools, training facilities, do-it-yourself and hobby workshops should not 

be handled unless supervised by trained, responsible personnel.
If you have doubts about how the equipment should be operated or how to connect it safely, consult a trained 

technician.
Handle the product with care. It can be damaged through impact, blows, or accidental drops, even from a 

low height.
Please also note the enclosed detailed operating instructions.

The mains outlet must be located near to the device and be easily accessible.
Never pull the mains plug from the socket by pulling at the cable. Always pull it from the mains socket using 

the intended grips.
Unplug the mains plug from the mains socket if you do not use the device for an extended period of time.
Disconnect the mains plug from the mains socket in thunderstorms for reasons of safety.
Make sure that the mains cable is not squeezed, bent, damaged by sharp edges or put under mechanical 

stress. Avoid excessive thermal stress on the mains cable from extreme heat or cold. Do not modify the 

mains cable. Otherwise the mains cable may be damaged. A damaged mains cable can cause a deadly 

electric shock.
Do not touch the mains cable if it is damaged. First, power down the respective mains socket (e.g. via the 

respective circuit breaker) and then carefully pull the mains plug from the mains socket. Never use the 

product if the mains cable is damaged.
A damaged mains cable may only be replaced by the manufacturer, a workshop commissioned by the 

manufacturer or a similarly qualified person, so as to prevent any danger.
Never plug in or unplug the mains plug when your hands are wet.

The digital oscilloscope is intended to be used for visualising electrical magnitudes and signals. Depending 

on the model, there are 2 or 4 independent input channels available for the measurement. 
The sensing heads are connected to the oscilloscope via BNC connectors.
The measured signals can be stored and displayed as a reference. The control of the device is performed 

via VDU-based control menus.
The max.input variables given on the device may never be exceeded. Use divider probes or attenuators if 

necessary.
The device should be connected to and operated with an earthed socket  of the public mains supply only.
Any use other than that described above could lead to damage to this product and involves the risk of short 

circuits, fire, electric shock, etc.
The product must not be changed or modified in any way. Do not open the housing. 
Measurements are not permitted in damp rooms or outdoors, nor under adverse environmental conditions.
Unfavourable ambient conditions are:
- Wetness or high air humidity,
- Dust and combustible gases, vapours or solvents,
- Thunderstorms or similar conditions such as strong electrostatic fields, etc. 
Always observe the safety notes included in these operating instructions.
This quick guide explains the safety measures that should be taken to make working with the device as 

safe as possible. The individual functions are described in more detail in the English operating instructions. 

These are located in the main directory on the attached CD. A Help menu is integrated additionally in the 

Oscilloscope (“HELP” button).

This device left the manufacturer’s factory in a safe and perfect condition.
We kindly request that the user observes the safety instructions and warnings contained in the enclosed 

operating instructions so this condition is maintained and to ensure safe operation. Please pay attention to 

the following symbols:

A triangle containing an exclamation mark indicates important information in these 

operating instructions that is to be observed without fail.

This is a class A device. It can cause radio interferences in residential areas; in this case, 

it can be demanded that the operator carries out appropriate measures.

Measurement category I for measurements on signal and control voltages without 

powerful discharges.

Measurement category II for measurements on electric devices connected to the mains 

supply by a power plug. This category also covers all smaller categories (e.g. CAT I for 

measuring signal and control voltages).
