PrecautionsGFG-3015 is specially designed for safety operation. It has passed through rigorous tests of inclement environment to ensure its reliability and good condition. The following precautions are recommended to insure your safety and keep the best condition of the equipment. (1) Safety Terms and Symbols The following terms and symbols may appear in this manual:! !This statement identifies conditions or practices that could result in injury or loss of life. This statement identifies conditions or practices that could CAUTION result in damage to this product or other properties. WARNINGThe following terms and symbols may appear on the product: This term indicates an immediately accessible injury hazard. DANGER This term indicates that an injury hazard may occur, but is WARNING not immediately accessible. This term indicates potential damage to this product or other CAUTION properties.!DANGER High voltage Protective Conductor Terminal ATTENTION refer to manual Double Insulated DANGER Hot surface Earth Ground Terminal(2) Do not place any heavy objects on the instrument under any circumstances.(3) Disassembling the instrument Due to the precision of this instrument, all the procedures of disassembling, adjusting, and maintenance should be performed by a professional technician. If the instrument has to be opened or adjusted under some unavoidable conditions, and to be managed by a technician who is familiar with GFG-3015. Once there is any abnormality, please contact our company or our distributor near you. (4) Power Supply AC input should be within the range of line voltage±15%, 50/60Hz. To prevent the instrument from burning up, be sure to check the line voltage before turning on power.p. 2GFG-3015(5) Grounding!WARNINGTo avoid electrical shock, the power cord protective grounding conductor must be connected to ground.GFG-3015 can be operated only with an earth grounded AC power cord that connects the case and ground well. This is to protect the user and the instrument from the risk of shock hazard. (6) Fuse Replacement!WARNINGFor continued fire protection, replace fuse only with the specific type and rating by qualified personnel. Disconnect the power cord before replacing fuse.The fuse blows only when there is any wrong on the instrument, which will stop working under this situation. Please find out the cause, then open the outside case (Please see the Figure (A), Figure (B) on below) and replace a proper fuse as listed below. Be sure to use the correct fuse before changing the applying location. F101 : T 0.8A/250V F100 : T 0.5A/250V Check the line voltage setting on the rear panel. If the line voltage setting does not match, Please change the line voltage setting according to the following steps: 1. Remove line cord from AC socket. 2. Switch the “AC line voltage switch” to correct setting with flat-blade screwdriver and reinsert.Figure (A) (7) Cleaning the Cabinet Disconnect the AC power cord before cleaning the instrument.Figure (B)Use a soft cloth dampened in a solution of mild detergent and water. Do not spray cleaner directly onto the instrument, since it may leak into the cabinet and cause damage. Do not use chemicals containing benzing, benzne, toluene, xylene, acetone, or similar solvents.GFG-3015p.3(8) Operation environment Indoor use Altitude up to 2000m Temperature to satisfy the specification : Operating temperature : Storage temperature : Relative humidity : Installation category： Pollution degree：18oC ~ 28oC (+64.4oF ~ +82.4oF) 0oC ~ 40oC (+32oF ~ +104oF) -10oC ~ 70oC (+14oF ~ 158oF) up to 90% when 0oC~35oC; up to 70% when 35oC~40oC CAT Ⅱ(The detail is as Table A) 2CAT Ⅳ CAT Ⅲ CAT Ⅱ CAT ⅠTable A For measurements performed at the source of the lowvoltage installation.

(10) For United KingdomAs the colours of the wires in mains leads may not correspond with the coloured markings identified in your plug/appliance, proceed as follows: The wire which is coloured Green and Yellow must be connected to the Earth terminal marked with the letter E or by the earth symbol or coloured Green or Green and Yellow. The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black. The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red. If in doubt, consult the instructions provided with the equipment or contact the supplier. This cable/appliance should be protected by a suitably rated and approved HBC mains fuse; refer to the rating information on the equipment and/or user instructions for details. As a guide, cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductorsNOTEThis lead/appliance must only be wired by competent persons.WARNINGTHIS APPLIANCE MUST BE EARTHEDIMPORTANTThe wires in this lead are coloured in accordance with the following codes: Green/Yellow :Earth Blue :Neutral :Live Brownwould normally require 13A types, depending on the connection method used. Any moulded mains connector that requires removal/replacement must be destroyed by removal of any fuse and fuse carrier and disposed of immediately, as a plug with bared wires is hazardous if engaged in a live socket. Any re-wiring must be carried out in accordance with the information detailed in this section.(Phase)p. 4GFG-30152. Product IntroductionThe frequency feedback method applied by GFG-3015 is a new technique that generates stable output frequency with extraordinary accuracy for Function Generator. The traditional function generators typically use integrating circuit and constant current circuit techniques that are easily affected by operation temperature or the quality of resistor or capacitor and other key components to occur poor frequency accuracy. The innovative design for GFG-3015 is to get rid of these problems. The frequency feedback system needs a compatible, powerful frequency counter. GW has designed his own full-function counter chip, GFC-9701, for this system with high frequency test range and full functions, including Period test, Duty test, Ratio test, Time interval, Pulse wide, direct display and direct connect with CPU system. GFG-3015 uses this Chip to read output frequency value at any time. Then CPU will modify the correct value of D/A converter immediately according to this value, so that the user can get a high accuracy frequency from GFG-3015 Function Generator. Besides, the GFG-3015 can also generate a high accuracy frequency to provide high frequency resolution.Graph1 indicates the fundamental construction of a frequency feedback system.D/A ConvertorVCOAMPO/PUser InterfaceCPUCounter (GFC-9701)Except the different design from the typical circuit, GFG-3015 system also has micro controller (CPU unit) equipping an additional RS-232 interface functions which will be used on any test system with other instrument or to be controlled by computer.GFG-3015p.53.
