- Page 9 ――――――――――――――――――――――――――― Measurement categories (Overvoltage categories) To ensure safe operation of measurement products, IEC 61010 establishes safety standards for various electrical environments, categorized as CAT I to CAT IV, and called measurement categories. These are defined as follows. CAT I : Secondary electrical circuits connected to an AC electrical outlet through a transformer or similar device.
- Page 10 ――――――――――――――――――――――――――― Higher-numbered categories correspond to electrical environments with greater momentary energy. So a measurement device designed for CAT III environments can endure greater momentary energy than a device designed for CAT II. Using a measurement product in an environment designated with a higher-numbered category than that for which the product is rated could result in a severe accident, and must be carefully avoided.
