Safety Notices
Review the following safety precautions carefully before operating the instrument
to avoid any personal injuries or damages to the instrument and any products
connected to it.
To avoid potential hazards use the instrument as specified by this user‟s guide
only.
The instrument should be serviced by qualified personnel only.
To Avoid Fire or Personal Injury.
Use Proper Power Cord.
Use the power cord designed for the instrument as
authorized in your country only.
Ground The Instrument.
The instrument is grounded through the grounding
conductor of the power cord. To avoid electric shock the instrument grounding
conductor(s) must be grounded properly before making connections to the input
or output terminals of the instrument.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all
ratings and marks on the instrument. Follow the user‟s guide for further ratings
information before making connections to the instrument.
Do Not Operate Without Covers.
Do not operate the instrument with covers
or panels
removed
.
Use Proper Fuse.
Use the fuse of the type, voltage and current ratings as
specified for the instrument.
Avoid Circuit or Wire Exposure.
Do not touch exposed connections and
components when power is on.
Do Not Operate With Suspected Failures.
If suspected damage occurs with
the instrument, have it inspected by qualified service personnel before further
operations.
Do Not Operate in Wet/Damp Conditions.
Do Not Operate in an Explosive atmosphere.
Keep Product Surfaces Clean and Dry.

  RIGOL
The disturbance test of all the models meet the limit values of A in the
standard of EN 61326: 1997+A1+A2+A3, but can’t meet the limit
values of B.
WARNING
IEC Measurement Category II. The HI and LO input terminals may be connected
to mains in IEC Category II installations for line voltages up to 300 VAC. To avoid
the danger of electric shock, do not connect the inputs to mains for line voltages
above 300 VAC.
Protection Limits: To avoid instrument damage and the risk of electric shock, do
not exceed any of the Protection Limits defined in the following section.
IEC Measurement Category II Overvoltage Protection
To protect against the danger of electric shock, the
RIGOL
DM3000 series
Digital Multimeter provides overvoltage protection for line-voltage mains
connections meeting both of the following conditions: The HI and LO input
terminals are connected to the mains under Measurement Category II conditions,
defined below, and The mains are limited to a maximum line voltage of 300 VAC.
IEC Measurement Category II includes electrical devices connected to mains at
an outlet on a branch circuit.
Such devices include most small appliances, test equipment, and other devices
that plug into a branch outlet or socket. The DM3000 series Digital Multimeter
may be used to make measurements with the HI and LO inputs connected to
mains in such devices, or to the branch outlet itself (up to 300 VAC). However,
the DM3000 series Digital Multimeter may not be used with its HI and LO inputs
connected to mains in permanently installed electrical devices such as the main
circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors.
Such devices and circuits are subject to overvoltage that may exceed the
protection limits of the DM3000 series Digital Multimeter.
Note
: Voltages above 300 VAC may be measured only in circuits that are isolated
from mains. However, transient overvoltage are also present on circuits that are
isolated from mains. The DM3000 series Digital Multimeter is designed to safely
withstand occasional transient overvoltage up to 2500 Vpk. Do not use this
equipment to measure circuits where transient overvoltage could exceed this
level.
