R&S RT-ZC20
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 device in an environment designated with a higher-numbered
category than that for which the device is rated could result in a severe accident,
and must be carefully avoided.
Never use a CAT I measuring device in CAT II, III, or IV environments.
The measurement categories comply with the Overvoltage Categories of the
IEC60664 Standards.
