The types of product users are: Unless explicitly allowed in the specifications, operating manual, and instrument labels, do not connect any instrument to mains. Responsible body is the individual or group responsible for use and maintenance of equipment, for ensuring that the equipment is operated within its specifications and Exercise extreme caution when a shock hazard is present. Lethal voltage may be present operating limits, and for ensuring that operators are adequately trained. on cable connector jacks or test fixtures. The American National Standards Institute Operators use the product for its intended function. They must be trained in electrical (ANSI) states that a shock hazard exists when voltage levels greater than 30 V RMS, safety procedures and proper use of the instrument. They must be protected from 42.4 V peak, or 60 V DC are present. A good safety practice is to expect that hazardous electric shock and contact with hazardous live circuits. voltage is present in any unknown circuit before measurin
