Safety Requirement
General Safety Summary
Please review the following safety precautions carefully before putting the
instrument into operation so as to avoid any personal injuries or damages to the
instrument and any product connected to it. To prevent potential hazards, please use
the instrument only specified by this manual.
Use Proper Power Cord.
Only the power cord designed for the instrument and authorized by local country
could be used.
Ground The Instrument.
The instrument is grounded through the Protective Earth lead of the power cord. To
avoid electric shock, it is essential to connect the earth terminal of power cord to the
Protective Earth terminal before any inputs or outputs.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratings and markers on the instrume nt and
check your manual for more information about ratings before connecting.
Use Proper Overvoltage Protection.
Make sure that no overvoltage (such as that caused by a thunderstorm) can reach
the product, or else the operator might expose to danger of electrical shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Use Proper Fuse.
Please use the specified fuses.
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit is powered.

Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by qualified
service personnel before further operations. Any maintenance, adjustment or
replacement especially to circuits or accessories must be performed by RIGOL
authorized personnel.
Keep Well Ventilation.
Inadequate ventilation may cause increasing of temperature or damages to the
device. So please keep well ventilated and inspect the intake and fan regularly.
Do Not Operate in Wet Conditions.
In order to avoid short circuiting to the interior of t he device or electric shock, please
do not operate in a humid environment.
Do Not Operate in an Explosive Atmosphere.
In order to avoid damages to the device or personal injuries, it is important to
operate the device away from an explosive atmosphere.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in air, please keep the surface of
device clean and dry.
Electrostatic Prevention.
Operate in an electrostatic discharge protective area environment to avoid damages
induced by static discharges. Always ground both the internal and external
conductors of the cable to release static before connecting.
Handling Safety
Please handle with care during transportation to avoid damages to keys, knob and,
interfaces as well as other parts on the panels.
The disturbance tests of all models conform to the P/F values of A based
on the standard of EN 61326: 1997+A1+A2+A3 instead of P/F values of
B.
DM3068 Quick Guide IV
Input Terminal Protection Limit
The protection limit applies to input terminals:
1． Main input (HI and LO) terminals
HI and LO terminals are used for Voltage, Resistance, Capacitance, Continuity,
Frequency and Diodes measurements and should be used under the following
two conditions:
1) HI-LO protection limit: at most 1000 VDC or 750 VAC, this is also the
maximum measurable voltage. The limit can be expressed as 1000 Vpk.
2) LO-ground protection limit: at most 500 Vpk (relative) is allowed to float at
LO terminal with safety.
Since the HI terminal holds a maximum protection of 1000 Vpk relative to the
ground, the sum of the “float” and mea sured voltages cannot exceed 10 00 Vpk.
2． Sampling (HI Sense and LO Sense/200 mA) terminals
HI Sense and LO Sense/200 mA terminals are used for 4-Wire Resistance
measurement and should be used under the following two conditions:
1) HI Sense-LO Sense/200 mA protection limit: 200 Vpk.
2) LO Sense/200 mA-LO protection limits: 0.5 Vpk. The current input fuse
on the rear panel provides the current passing through LO Sense/200
mA up to 250 mA protection.
3． Current input (10 A and Sense/200 mA) terminals
10 A and LO terminals are used for current measurements of 2 A and 10 A. The
maximum current which goes through the 10 A terminal is limited to 10 A by
the internal fuse. LO Sense/200 mA and LO terminals are used for current
measurements ranging from 200 µA to 200 mA. The maximum current which go
through the LO Sense/200 mA terminal is limited to 250 mA by the internal
fuse.
NOTE:
In order to prevent the fuse from blowing out and protect the
multimeter, please use the current input terminals according to the
following requirements:
1) Do not connect the 10 A and LO Sense/200 mA input terminals into the
current measuring circuit at the same time.
2) Only use 10 A and LO terminals for measurements when the measured

V
RIGOL
current AC+DC RMS value goes within 200 mA and 10 A.
3) Select a proper current input terminal according to the estimated current
magnitude before connect the multimeter to AC supplies if you want to use
current measurement.
4) The current into 10 A cannot exceed 13.5 A, otherwise it will blow out the
internal fuse; while the current into the LO Sense/200 mA terminal
cannot exceed 300 mA, ot herwise the current fuse from the rear panel may
be blown out.
IEC II Overvoltage Protection
In order to prevent electric shock, DM3068 provides overvoltage protection for
line-voltage mains connections meeting both of the following conditions:
1． The HI and LO input terminals are connected to the mains under Measurement
Category II conditions, defined below.
2． The mains are limited to a maximum line voltage of 300 VAC.
WARNING: IEC II includes electrical devices c onnected to mains at an outlet on a
branch circuit. Such devices include most small appliances, test equipments and
other devices that inserted into a branch socket.
DM3068 may be used to make measurements with the HI and LO inputs connected
to mains in such devices (up to 300 VAC), or to the branch socket itself. However,
DM3068 may be used with its HI and LO inputs connected to mains from neither
permanently installed electrical device such as a main circuit-breaker panel,
sub-panel disconnected box nor wired motors. Such devices and circuits are readily
to beyond the protection from DM3068.
NOTE: Voltages above 300 VAC may be measured only in circuits that are isolated
from mains. However, a transient overvoltage is also present in such circuits.
DM3068 was designed to safely withstand occasional transient overvoltage up to
2500 Vpk. Do not use this device to measure circuits whose transient overvoltage
may exceed this level.
