8. Remove the battery from the meter if the meter is to be stored for

long periods.

9. To avoid electric shock, do not measure AC current on any circuit

whose voltage exceeds 500V AC.

10. Voltage checks on electrical outlets can be difficult and misleading

because of the uncertainty of connection to the electrical contacts.

Other means should be used to ensure that the terminals are not

"live".

11. The product is intended only for indoor use

12. If the equipment is used in a manner not specified by the

manufacturer, the protection provided by the equipment may be

impaired.

PER IEC1010 OVERVOLTAGE INSTALLATION CATEGORY

OVERVOLTAGE CATEGORY I

Equipment

of

OVERVOLTAGE

CATEGORY

I

is

equipment

for

connection to circuits in which measures are taken to limit the transient

overvoltages to an appropriate low level. Note – Examples include

protected electronic circuits.

OVERVOLTAGE CATEGORY II

Equipment of OVERVOLTAGE CATEGORY II is energy-consuming

equipment to be supplied from the fixed installation.

Note – Examples include household, office, and laboratory appliances.

OVERVOLTAGE CATEGORY III

Equipment of OVERVOLTAGE CATEGORY III is equipment in fixed

installations.

Note – Examples include switches in the fixed installation and some

equipment for industrial use with permanent connection to the fixed

installation.

OVERVOLTAGE CATEGORY IV

Equipment of OVERVOLTAGE CATEGORY IV is for use at the origin of

the installation.

Note – Examples include electricity meters and primary over-current

protection equipment
