II SDM3045X Quick Start

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.

SDM3045X Quick Start III

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 overvoltage protection.

Make sure there is no overvoltage (like voltage caused by

thunder and lightning) reaching to the instrument, otherwise

the operator may suffer an electric shock.

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.

IV SDM3045X Quick Start

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, Diode and temperture

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.

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.

SDM3045X Quick Start V

IEC Measurement Category II Overvoltage Protection

SDM3045X Digital Multimeter provides overvoltage protection

for line-voltage mains connections meeting both of the

following conditions to avoid the danger of electric shock：

1. The HI and LO input terminals are connected to the

mains under Measurement Category II conditions as

following.

2. The maximum line voltage of the mains is 300VAC.

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.

SDM3045X is capable of making measurements with the HI

and LO inputs connected to mains in such devices (up to

300VAC) or the branch outlet itself. However, the HI and LO

terminals of SDM3045X 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 SDM3045X.

NOTE:

Voltages above 300VAC only can be measured in circuits that

are isolated from mains. However, there may be transient

overvoltage in circuits that are isolated from mains. SDM

3045X is able to withstand occasional transient overvoltage

up to 4000Vpk. Please don’t use this instrument to measure

circuits that transient overvoltage may exceed this level

Daily Maintenance and Cleaning

Maintenance

When storing or placing the instrument, please avoid the

liquid crystal display from direct sunlight for a long time.

NOTE:

 To avoid damages to the instrument or test leads, please

don’t place them in mist, liquid or solvent.

Cleaning

Please often clean the instrument and test leads according

to the use of them.

 Wipe the external ash of the instrument and test leads by a

soft rag. Be careful not to scratch the transparent plastic

protective screen when cleaning the liquid crystal screen.

 Use a soft rag that has been soaked by water to clean the

instrument after cutting off the power. Or use 75%

isopropyl alcohol of water solvent to get a more thorough

cleaning.

NOTE:

 To prevent the surface of the instrument or test leads from

damages, please don’t use any corrosive or chemical

cleaning reagents.

Please make sure the instrument is already dry before

restarting it to avoid short circuits or personal injuries

caused by water.
