Page 413: Appendix C: Inspection And Cleaning
Appendix C: Inspection and Cleaning Inspect and clean the instrument as often as operating conditions require. The collection of dirt can cause instrument overheating and breakdown. Dirt acts as an insulating blanket, preventing efficient heat dissipation. Dirt also provides an electrical conduction path that can cause an instrument failure, especially under high-humidity conditions.
Page 414 Appendix C: Inspection and Cleaning Cleaning the Instrument Exterior WARNING. To avoid injury or death, unplug the power cord from line voltage before cleaning the instrument. Avoid getting moisture inside the instrument during external cleaning. Use only enough liquid to dampen the cloth or appli- cator.

Page 435: Waveform Edit
Appendix F: Theory of Operation However, when you use waveform data to generate another waveform by mathematical operation such as multiplying, dividing, adding, etc., you must keep the waveform data as waveform file. The waveform file format exists for keeping the data precision in mathematical operations. For more details about file format, refer to Data Transfer section in AWG500 Programmer Manual.
