3Brief Instruction
3.1 Unpacking
3.1.1 Model Confirmation
After opening the packing box,you will see the following items:
S1131 Signal Generator x1
Three-wire Power Cord x 1
CD x 1
Please check the above items against the Purchase Contract and the Packing List. If any problem, please contact Saluki and
we will deal with the problem assoon as possible.
3.1.2 Appearance Inspection
Inspect carefully whether the instrument has any damage during transportation. If the instrument has obvious damage, it is
strictly forbidden to be poweredon. Please contact Saluki and we will repair or exchange it be as soon as possible.
3.1.3 Operating Environment
Refer to the part of environment adaptability in the technical specifications of appendix 1. In addition, pay special attention to
the following requirements:
Power supply: 110 – 220V ±15%，50Hz – 60Hz ±5%，20W
Power socket: a three-wire supply socket that must be grounded reliably.
Instrument power cord: packed three-wire power cord
Before connecting the Signal Generator with the power supply, please carefully verify if the
power supply voltage. Otherwise, it is much possible to damage the instrument or even
cause personal injuries with wrong power supply.
To prevent or reduce the possible damage to the internal hardware of the signal generator
due to the mutual interference caused by multi equipment through the power supply,
especially the peak pulse interference caused by high-power equipment, it is best to use a
220V/110V AC stabilized-voltage power supply to supply power for the signal generator.

11
Bad grounding or failure of the power supply may cause damage to the instrument, even
personal injury. Before connecting the power supply of signal generator, make sure ground
wires ofthe instrumentand its power supply are in good contact.
Use a power socketwith protective grounding and do not substitute the protective ground
wire with an external cable.
3.1.4 Electrostatic Protection
ESD can damage or destroy electronic components and equipment. Antistatic measures are usually taken to prevent ESD
damage: conductive table–mat and wrist–strap combination as well as conductive floor–mat and heel–strap combination. Both
types, when used together, provide a significant level of ESD protection. Among the two, only the table–mat and wrist–strap
combination provides adequate ESD protection when used alone. To ensure user safety, the static–safe accessories must
provide at least 1 MΩ resistance to ground.
Please use the following antistatic measures correctly to reduce the damage of electrostatics:
Ensure all the instruments are grounded correctly to prevent the electrostatics being generated.
Before touch the joint and corewire or do any assembly operation, do wear antistatic wrists or take other antistatic measures.
The above antistatic measures shall not be taken where the voltage is larger than 500V.
3.1.5 First Power Up
1) Connect the provided power cord instrument end to the power socket on rear panel.
2) Ensure theAC power is compliant to requirement.
3) Check the power switch on rearpanel and ensure it is off (“O”)
4) Connect the other end toAC power
5) Turn on the switch on rear panel (“|”)
6) Press the power button on front panel.
7) Screen lighted and the instrument is on.
8) For an accurate measurement, please warm up the signal generator for at least 30min before measurement.

3.2 Routine Maintenance
It is required to check and cleanthe instrument after a period ofuse. Please proceed as the following procedures:
1) Shut down.
2) Unplug the power cord.
3) Use a clean and soft cloth withdetergent to wipe the keys gently.
4) Wipe up the display with a clean and soft cloth.
5) Check other sides of the instrument and ensure no damage
6) Clean other sides of the instrument with a soft cloth. Please pay attention to the ports and interfaces, do not clean them
and avoid any scratches which may impact themeasurement in future.
7) Plug in the power cord after thedisplay is dried out.
There is a layer of Anti Static Coatings (ASC) applied on the surface of the display screen, so
never use the cleaner containing fluoride, acidic cleaner or alkali cleaner. Never spray cleaner
over the display panel, otherwise the cleaner may seep into and damage the instrument.
