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 groundi ng 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.
Do Not Operate in an Explosive atmosphere.

standard of EN 61326: 1997+A1+A 2+A3, but can’t meet the P/F values
of B.
Input Terminal Protectio n Limitation
Protection limitation is defined for the input terminal:
1． Mai n 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 exc eed 1000 Vp k.
2． Sampli ng (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
I and LO terminal are used for current measurement. The maximum current
which go through the I terminal 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/DM3058E 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.
User’s Guide for DM3058/DM3058E
Page 6
RIGOL
IV
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/DM3058E may be used to make measurements with the HI and LO inputs
connected to mains in such devices (up to 600 VAC), or to the branch outlet itself.
However, DM3058/DM3058E 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 th e protecti o n lim its of
DM3058/DM3058E.
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/DM3058E 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.

To Select Range
For the multimeter, appropriate range could be selected according to the signals
input by “Automatic” or “Manual”. In Manual mode, you can obtain higher reading
precision via range select keys on the right side of the Front Panel. See the figure
below.

Explanations:
When the input signal is beyond the current sc ope of the measurement range,
the multimeter will show “OVER LOAD”.
After restarting and remote reset, range options will turn back to default
“Auto”.
You are suggested to select “Auto” range so as to protect the instrument
against damage and get ex ac t datum as much as possible when it is hard to
predict the range of measurement.
The range is fixed during testing the Continuity and Diodes. The range of
Continuity is selected as 2kΩ while the Diodes are 2.4V
.
Other functions of the d irection keys:
In the Save interface, Up and Down keys are used to select location for
the saving files.
During inputting data, Up and Down keys are used to change the

2.5 reading/s belongs to “Slow” rate; the mark of St atus Bar is “S” and the rate of
refurbishing is 2.5Hz.
20 reading/s belongs to “Middle” rate, the mark of Status Bar is “M” and the rate of
refurbishing is 20Hz.
123 reading/s belongs to “Fast” rate, the mark of Status Bar is “F” and the rate of
refurbishing is 50Hz.
Measurement rate could be controlled by Lef t and Right direction k e y. Each press
for the Left key, one level will be increased for rate, vice versa.

2. To set as linkage for both reading resolution and reading (measurement) rate.
2.5 reading/s belongs to 5.5 digit resolution.
Both 20 reading/s and 123 reading/s belong to 4.5 digit resolution.
The reading resolution of Sensor is fixed at 5.5 digit and both “M” a nd “S” rate
can be chosen.
The reading resolutions and measurement rat es of both Diode and Continuity

Example 1: Reading Statistic Functions
How to realize the statistic func tion of maximum value for readings during
measuring.
During the maximum value statistic calculation, the first reading is taken as the
maximum value and b eing shown on the display. It will be refreshed to new
maximum value sub sequentially.
Operating Steps:
1. Press
appropriate measurement range.
2. Conn ect test le ads as Figure 2-8.
3. Set the Sta tisti c m eas urement functi o n parameters.
4. Press Stats MAX ON to statistic maximum value from the
measurement result.
5. Lead test leads into the circuit and start to measure.
As shown below, current Statistic State is “MAX” and current reading is the
maximum of all. See the figures below, the maximum value will refresh with
sample counts.
