• If you have reason to assume that safe operation is no longer possible, disconnect
the device immediately and secure it against inadvertent operation. It can be
assumed that safe operation is no longer possible if:
- the device is visibly damaged,
- the device no longer works
- the unit was stored under unfavourable conditions for a long period of time or
- if it has been subjected to considerable stress in transit.
• Never switch the device on immediately after having taken it from a cold to a warm
environment. Condensation that forms might destroy your device. Allow the device
to reach room temperature before switching it on.
• Never disassemble the product! There is a risk of a fatal electric shock.
• Do not carelessly leave the packaging material lying around since this may become
a dangerous toy for children.
• The product is only suited for dry indoor rooms (not bathrooms or similar damp
interiors). The device must not get wet or damp. There is a risk of a fatal 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.
• Handle the product with care. It can be damaged through impact, blows, or
accidental drop, even from a low height.
• Please also observe the attached 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.
b) Miscellaneous
• Consult an expert when in doubt about operation, safety or connection of the
device.
•
Maintenance, modifications and repairs are to be performed exclusively by an
expert or at a qualified shop.
• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.
GW-INSTEK AFG-2225
Arbitrary function generator
Version 06/14
Item no. 630771
Intended use
The function generator generates signals with different waveforms as well as adjustable
amplitudes. The display shows the functions. Due to the digital synthesiser the output signals
are highly precise and frequency-stable.
The measuring is conducted via BNC-connectors.
The maximum measuring voltage indicated on the device must never be exceeded. Use divider
probes if necessary.
The device should only be connected to and operated on an earthed socket (Schuko socket)
of the public AC power supply.
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 modified or converted, and the casing must not be opened.
Measurement in a dump location or outdoors or under ambient environment conditions is not
permitted. Unfavourable ambient conditions are:
- Wet conditions or high air humidity
-
Dust and flammable gases, vapours or solvent,
-
Thunderstorms or similar conditions such as strong electrostatic fields etc.
Always observe the safety notes included in these operating instructions.
This quick guide explains safety measures to make working with the device as safe as possible.
The individual functions of the device are described in more detail in the enclosed operating
manual.
Safety instructions
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information
on proper handling in this manual, we assume no liability for any resulting
personal injury or damage to property. Such cases will invalidate the warranty/
guarantee.
a) Persons / Product
•
The unauthorised conversion and/or modification of the product is inadmissible
because of safety and approval reasons (CE).
• The construction of the product corresponds to protection class 1. Only a correct
earthed mains socket (115 / 230 V/AC) of the public power supply should be used.
• Measuring devices and devices connected to the power supply should be kept out
of reach of children. Be thus especially careful when children are around.
• First, connect the BNC-output of the measuring line to the generator, then connect
the probe to the electric circuit to be measured. When the measuring is completed,
please disconnect the measuring contacts first before disconnecting the BNC
output of the probe from the generator.
• Take particular care when dealing with voltages exceeding 25 V/AC or 35 V/DC!
Even at such voltages you can receive a life-threatening electric shock when you
come into contact with electric wires.
• Prior to each measurement, check your instrument and its measuring leads for
damage. Never carry out any measurements if the protecting insulation is defective
(torn, ripped off etc.)
• To avoid an electric shock, make sure not to touch the connections/measuring
points to be measured neither directly nor indirectly during measurement.
• Never touch the probes outside of the marked handling area during a measurement.
There is the risk of a fatal electric shock.
• Do not use the device shortly before or after a thunderstorm (lightning! / high-
energy overvoltages!). Make sure that your hands, shoes, clothing, the floor, the
measuring device and/or measuring lines, the circuits and also parts of it are
always dry.
•
Do not use the product within rooms or in bad ambient conditions where flammable
gases, vapours or explosive dust may be present or are present.
• Avoid operation near:
-
strong magnetic or electromagnetic fields
- transmitter aerials or HF generators,
- Since this could affect the measurement.
•
Only use measuring lines or equipment harmonised with the specifications of this
oscilloscopes for measuring. Only dual or specially insulated measuring equipment
may be used (e.g. fully insulated BNC adapters, etc.)
