Exactly what it says on the tin. I have a Sound Blaster X-Fi Xtreme Audio Notebook sound card and I was measuring its output frequency using frequency counter connected to the card's output. Frequency was generated using a program called FrequencyGenerator.
This article contains information about Cathodic Protection. Cathodic Protection is an electrochemical means of corrosion control in which the oxidation reaction in a galvanic cell is concentrated at the anode and suppresses corrosion of the cathode in the same cell. Figure 1 shows a simple cathodic protection system.
CATHODIC PROTECTION (CP) PROGRAM. NACEâs Cathodic Protection (CP) Program is the most specified and recognized CP training and certification* in the world. This program provides students with the theoretical and practical fundamentals for testing, evaluating, and designing both galvanic and impressed current cathodic protection systems. IMPORTANT CHANGE REGARDING THE CP1 - TESTER, CP2 - TECHNICIAN, CP3 - TECHNOLOGIST, AND CP4 - SPECIALIST EXAMINATION PROCEDURES.
