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.
Avoid Fire or Personal Injury.
Use Proper Power Cord.
Only the power cord designed for the instrument as authorized in your country
could be used.
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.

Input Terminal Protection Limitation
Protection limitation is defined for the input terminal:
1．Main input (HI and LO) terminal
HI and LO terminals are used for Voltage, Resistance, Capacitance, Continuity,
Frequency and Diodes measurement. Two protection limitations are defined:
1) HI-LO protection limitation: 1000 VDC or 750 VAC. It is the maximum
measurable voltage. The limitation can be expressed as 1000 Vpk.
2) LO-ground protection limitation. LO terminal can safely “float” 500 Vpk
relative to the ground.
The maximum protection limitation of HI terminal relative to the ground is
1000 Vpk. Therefore, the sum of the “float” voltage and the measured voltage
cannot exceed 1000 Vpk.
2．Sampling (HI Sense and LO Sense) terminal
HI Sense and LO Sense are used for 4-Wire Resistance Measurement. Two
protection limitations are defined:
1) HI Sense-LO Sense protection limitation: 200Vpk.
2) LO Sense-LO protection limitation: 2Vpk.
3．Current input (I) terminal
Iand LO terminal are used for current measurement. The maximum current
which go through the Iterminal is limited to 10A by the fuse on the rear
panel.
NOTE: Voltage on the current input terminal corresponds to voltage on LO
terminal. To obtain favorable protection, specified fuse should be used.
IEC Measurement Category II Overvoltage Protection
To protect against the danger of electric shock, DM3058 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 600 VAC.
WARNING: 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.
DM3058 may be used to make measurements with the HI and LO inputs connected

RIGOL
User’s Guide for DM3058
V
to mains in such devices (up to 600 VAC), or to the branch outlet itself. However,
DM3058 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 disconnected boxes, or permanently wired motors. Such devices and
circuits are subject to overvoltage that may exceed the protection limits of DM3058.
NOTE：Voltages above 600 VAC may be measured only in circuits that are isolated
from mains. However, transient overvoltage is also present on circuits that are
isolated from mains. DM3058 is designed to safely withstand occasional transient
overvoltage up to 4000Vpk. Do not use this equipment to measure circuits where
transient overvoltage could exceed this level.
