THE TEST EQUIPMENT
The test equipment I use is the state-of-the-art Seaward Apollo 400. This machine has been calibrated as required. I chose this machine as it is the most up to date industry standard machine, widely recognised as one of the most powerful and versatile testing machines on the market.
What does and doesn't need testing
Anything that connects to mains electricity needs a test and certificate. So;
Mains cables, extension blocks and reels, powered (active) speakers, mixing desks, guitar and bass combos and amplifiers, PSUs (power supply units for fx pedals, radio mic receivers etc), IEC (kettle) leads (note; these are a test in their own right), stage lighting, computers, laptop PSUs, power amplifiers, domestic appliances, battery chargers, CDJs, turntables, DJ mixers, electronic keyboards (or their PSUs).
Items that do not need testing include: microphones, guitars, audio leads, passive speakers, battery operated items, low voltage items requiring a PSU.
Typical Test procedure
Below are a sequence of shots showing each stage of testing an IEC lead. Other types of equipment have differenct test settings but follow a simliar plan.
