reinforced insulaon.
2-2.Per IEC1010 Overvoltage Installaon Category Overvoltage Category I
Equipment of Overvoltage Category I is equipment for connecon 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
xed installaon.
Note: Examples include household, oce, and laboratory appliances.
Overvoltage Category III
Equipment of Overvoltage Category III is equipment in xed installaons.
Note: Examples include switches in the xed installaon and some equipment for
industrial use with permanent connecon to the xed installaon.
Overvoltage Category IV
Equipment of Overvoltage Category IV is for use at the origin of the installaon.
Note: Examples include electricity meters and primary over-current protecon equipment.
2-3.Safety Instrucons
• This meter has been designed for safe use, but must be operated with cauon.
• The rules listed below must be carefully followed for safe operaon.
1.Never apply voltage or current to the meter that exceeds the specied maximum:

1000VDC/AC rms
1000VDC/AC rms
2.Use extreme CAUTION when working with high voltages.
3.Do not measure voltage if the voltage on the “COM” input jack exceeds 1000V above
earth ground.
4.Never connect the meter leads across a voltage source while the funcon switch
is in the current, resistance, or diode mode, doing so can damage the meter.
5.Always discharge lter capacitors in power supplies and disconnect the power
when making resistance or diode tests.
6.Always turn o the power and disconnect the test leads before opening the covers
to replace the fuse or baeries.
7.Never operate the meter unless the back cover and the baery and fuse covers are in
place and fastened securely.
8.If the equipment is used in a manner not specied by the manufacturer, the
protecon provided by the equipment may be impaired.
