Fig. 1-2: Examples of measurement categories
The higher the category, the higher the expected transient overvoltage. Overvol-
tages can overload a circuit and cause electrical and physical damage. Therefore,
use the measurement instrument only in electrical environments for which the
instrument is rated.
The measurement categories correspond to the overvoltage categories of the
IEC60664 standards. Working voltages stated in context with measurement cate-
gories are always specified as effective voltages V (RMS) against earth ground.
