voltages above 500V in Category installations
Overvoltage installations categories per IEC
61010-1, 2000: The meter is designed to protect
against transients in these categories:
CAT I From high-voltage low-energy sources,
e.g., electric circuits or a copy machine

and household appliances
CAT III From equipment in fixed equipment
installations, e.g. installation panels,
