PeakTech DDS Arbitrary Waveform Generator Operation manual

1. Safety Precautions This product complies with the requirements of the following European Community Directives: 2014/130/EU (Electromagnetic Compatibility) and 2013/35/EU (Low Voltage) as amended by 2014/32/EU (CE-Marking). Overvoltage category II; pollution degree 2. To ensure safe operation of the equipment and eliminate the danger of serious injury due to short-circuits (arcing), the following safety precautions must be observed. Damages resulting from failure to observe these safety precautions are exempt from any legal claims whatever. * The instrument must be set up so that the...

Do not subject the equipment to shocks or strong vibrations. Do not operate the equipment near strong magnetic fields (motors, transformers etc.) Keep hot soldering irons or guns away from the equipment. Allow the equipment to stabilize at room temperature before taking up measurement (important for exact measurements). Do not input values over the maximum range of each measurement to avoid damages of the meter. Use caution when working with voltages above 35V DC or 25V AC. These Voltages pose shock hazard. Periodically wipe the cabinet with a damp cloth and mid detergent. Do not use...

2. Quick Start If it’s the first time for you to use the generator or you have no time to read the guide carefully, you can get the basic operation as soon as you finish browsing the chapter1. If more complicated functions are needed or meet difficulties in operation, please read Features and Functions in chapter 3. 2.1 Prepare the waveform generator for use 2.1.1 Check the list of supplied items Verify that you have received the complete unit according to the packing list. If you find package damaged badly, leave it until the instrument passes performance test. If anything is missing,...

Warning: In order to ensure the security of the operator, use triple- core power socket with ground wire.
