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.

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.

Do not operate the instrument with covers or panels removed.

Use Proper Fuse.

Please use the fuse that its 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.

Keep Well Ventilated.

Do Not Operate in Wet/Damp Conditions.

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

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.

DM3058 Digital Multimeter Overview

RIGOL DM3058 is an instrument especially designed for high-precision,

multifunction, and automation measurements. It realized a combination of basic

measurement function and multifold math functions as well as Random Sensor

measurement function.

The DM3058 holds a high-resolution monochrome LCD display system with clear

keyboard layout and operation hints to make it easier and agility to use. Besides, it
