II SDM3055 Digital Multimeter

General Safety Summary

Read the following safety precautions carefully to avoid any personal injuries
or damages to the instrument and any products connected to it. To avoid
potential hazards, please use the instrument as specified.

Use proper power line.

It‟s only allowed to use the special power line which is approved by local

state.

Ground the instrument.

The instrument is grounded through the protective terra conductor of the
power line. The ground conductor must be connected to the earth to avoid
electric shock. Make sure the instrument is grounded correctly before
connecting its input or output terminals.

Connect the signal wire correctly

The potential of the signal wire is equal to the earth, so do not connect the
signal wire to a high voltage.

Observe all terminal ratings

Please observe all ratings and sign instructions on the instrument to avoid fire
or electric shock. Before connecting the instrument, please read the manual
carefully to gain more information about the ratings.

Do not operate with suspected failures

If you suspect that the product is damaged, please contact SIGLENT‟s

qualified service personnel to inspect it. Any repair and adjustment to the
product or replacing a component should be done by qualified personnel
only.

Avoid circuit or wire exposure

Don‟t touch exposed contacts or components when the power is on.

Don’t operate without covers.

Don‟t operate the instrument with covers or panels removed.

Use proper fuse.

It‟s only allowed to use the specified fuse for the instrument.

Use proper over-voltage protection.

Make sure there is no over-voltage (like voltage caused by thunder and
lightning) reaching to the instrument, otherwise the operator may suffer an
electric shock.

SIGLENT

SDM3055 Digital Multimeter III

Antistatic protection.

Static electricity will cause damages to the instrument, so test in antistatic
areas as far as possible. Ground its inner and outer conductors to release the
static electricity temporarily before connecting the cable to the instrument.

Keep good ventilation.

Improper ventilation will cause the rise of the instrument‟s temperature. Keep

good ventilation and check the vent and fan regularly when using it.

Keep the surface of the instrument clean and dry.

Do not operate in wet or damp conditions.

Do not operate in flammable or explosive environment.

The disturbance test of all the models meets the limit values of A in the
standard of EN 61326-1:2013.

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 Diode measurement. Two protection limitations
are defined:
 HI-LO protection limitation: 1000VDC or 750AVC. It‟s the maximum
measurable voltage. The limitation can be expressed as 1000Vpk.
 LO-ground protection limitation ： LO terminal can “float” 500Vpk
relative to the ground safely. The maximum protection limitation of HI terminal

relative to the ground is 1000Vpk. Therefore, the sum of the “float” voltage

and the measured voltage can‟t exceed 1000Vpk.

2. Sampling (HIsense and LOsense) terminal
HIsense and LOsense are used for 4-wire Resistance measurement. Two

protection limitations are defined:

 HIsense-LOsense protection limitation: 2000Vpk.
 LOsense-LOsense protection limitation: 2Vpk.

SIGLENT

IV SDM3055 Digital Multimeter

3. Current input (I) terminal
I and LO terminals are used for current measurement. The maximum

current which go through the I terminal is limited to 10A by the fuse on the
back panel.

NOTE:

Voltage on the current input terminal corresponds to voltage on LO terminal.
To keep good protection, only use the fuse of specified type and level to
replace this fuse.

IEC Measurement Category II Over-voltage Protection

SDM3065X Digital Multimeter provides over-voltage protection for
line-voltage mains connections meeting both of the following conditions to
avoid the danger of electric shock：

 The HI and LO input terminals are connected to the mains under

Measurement Category II conditions as following.

 The maximum line voltage of the mains is 600VAC.

WARNING:

IEC Measurement Category II includes electrical devices connected to mains
at an outlet on a branch circuit, such as most small appliances, test
equipments, and other devices that plug into a branch outlet or socket.

SDM3065X is capable of making measurements with the HI and LO inputs
connected to mains in such devices (up to 600VAC) or the branch outlet itself.
However, the HI and LO terminals of SDM3065X can‟t be connected to
mains in permanently installed electrical devices such as the main
circuit-breaker panels, sub-panel disconnected boxes and permanently wired
motors. Such devices and circuits are prone to exceed the protection limits of
SDM3065X.

NOTE:

Voltages above 600VAC only can be measured in circuits that are isolated
from mains. However, there may be transient over-voltage in circuits that are
isolated from mains. SDM3065X is able to withstand occasional transient
over-voltage up to 4000Vpk. Please don‟t use this instrument to measure
circuits that transient over-voltage may exceed this level.

Measurement Configuration

Most measurement parameters are user-defined. Changing a measurement
parameter will change the measurement precision and speed as well as the
input impedance. An appropriate measurement parameter based on the actual
application will ensure faster measurement or higher measurement precision.

The default measurement configurations of the multimeter can ensure the
accuracy of the measurement results in most cases. Users can directly use
these defaults for any measurement or modify the parameters of the
measurement function as required.

The parameters for different measurement function differ, see table below.
