This symbol indicates that a device is protected throughout by double insulation or
reinforced insulation.
2-2.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.
2-3.Safety Instructions
• This meter has been designed for safe use, but must be operated with caution.
• The rules listed below must be carefully followed for safe operation.
1.Never apply voltage or current to the meter that exceeds the specified maximum:

800mA 1000V fast acting fuse
10A 1000V fast acting fuse
(10A for 30 seconds max every 10 minutes)
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 function switch
is in the current, resistance, or diode mode, doing so can damage the meter.
5.Always discharge filter capacitors in power supplies and disconnect the power
when making resistance or diode tests.
6.Always turn off the power and disconnect the test leads before opening the covers
to replace the fuse or batteries.
7.Never operate the meter unless the back cover and the battery and fuse covers are in
place and fastened securely.
8.If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
