WARNING

Warning: Identifies conditions or practices that could

result in injury or loss of life.

CAUTION

Caution: Identifies conditions or practices that could

result in damage to the instrument or to other properties.

DANGER High Voltage

Attention Refer to the Manual

Protective Conductor Terminal

Earth (ground) Terminal

Do not dispose electronic equipment as unsorted

municipal waste. Please use a separate collection facility

or contact the supplier from which this instrument was

purchased.

T3MIL Series User Manual

Safety Guidelines

General Guideline

CAUTION

Do not place any heavy objects on the instrument.

Avoid severe impact or rough handling that leads to

damaging the instrument.

Do not discharge static electricity to the instrument.

Use only mating connectors, not bare wires, for the

terminals.

Do not disassemble the instrument unless you are

qualified as service personnel.

(Note) EN 61010-1:2010 specifies the measurement categories and

their requirements as follows. The T3MIL50/50X doesn’t fall

under category II, III or IV.

Measurement category IV is for measurements performed at the

source of low-voltage installation.

Measurement category III is for measurements performed in the

building installation.

Measurement category II is for measurements performed on the

circuits directly connected to the low voltage installation.

Power Supply

WARNING

AC Input voltage: 100 - 240 V AC, 50 - 60Hz, 25VA

The power supply voltage should not fluctuate more

than 10%.

Connect the protective grounding conductor of the AC

power cord to an earth ground, to avoid electrical

shock.

Cleaning the

T3MIL50/50X

Disconnect the power cord before cleaning.

Use a soft cloth dampened in a solution of mild

detergent and water. Do not spray any liquid into the

instrument.

Do not use chemicals or cleaners containing harsh

material such as benzene, toluene, xylene, and acetone.

Operation

Environment

Location: Indoor, no direct sunlight, dust free, almost

non-conductive pollution (Note below)

Temperature Range: 0~35°C, Relative Humidity:

<80%RH; >35°C, Relative Humidity: <70%RH

Altitude: < 2000m

Operating Environment: 0°C to 40°C (operation)

Pollution Degree 2

SAFETY INSTRUCTIONS

(Note) EN 61010-1:2010 specifies the pollution degrees and their

requirements as follows. The T3MIL50/50X falls under degree 2.

Pollution refers to “addition of foreign matter, solid, liquid, or

gaseous (ionized gases), that may produce a reduction of dielectric

strength or surface resistivity”.

Pollution degree 1: No pollution or only dry, non-conductive pollution

occurs. The pollution has no influence.

Pollution degree 2: Normally only non-conductive pollution occurs.

Occasionally, however, a temporary conductivity caused by

condensation must be expected.

Pollution degree 3: Conductive pollution occurs, or dry,

non-conductive pollution occurs which becomes conductive due to

condensation which is expected. In such conditions, equipment is

normally protected against exposure to direct sunlight, precipitation,

and full wind pressure, but neither temperature nor humidity is

controlled.

Storage

Environment

Location: Indoor

Storage Conditions: −10°C to 70°C

Temperature Range: 0~35°C, Relative Humidity:

<90%RH; >35°C, Relative Humidity: < 80%RH

Disposal

Do not dispose this instrument as unsorted municipal

waste. Please use a separate collection facility or contact

the supplier from which this instrument was purchased.

Please make sure discarded electrical waste is properly

recycled to reduce environmental impact.

T3MIL Series User Manual

Power cord for the United Kingdom

When using the instrument in the United Kingdom, make sure the power

cord meets the following safety instructions.

NOTE: This lead / appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in accordance with the

following code:

Green/ Yellow:

Earth

Blue:

Neutral

Brown:

Live (Phase)

As the colours of the wires in main leads may not correspond with the

coloured marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth

terminal marked with either the letter E, the earth symbol or coloured

Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal which is

marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the terminal marked

with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment or contact

the supplier.

This cable/appliance should be protected by a suitably rated and approved

HBC mains fuse: refer to the rating information on the equipment and/or

user instructions for details. As a guide, a cable of 0.75mm2should be

protected by a 3A or 5A fuse. Larger conductors would normally require 13A

types, depending on the connection method used.

Any exposed wiring from a cable, plug or connection that is engaged in a live

socket is extremely hazardous. If a cable or plug is deemed hazardous, turn

off the mains power and remove the cable, any fuses and fuse assemblies. All

hazardous wiring must be immediately destroyed and replaced in accordance

to the above standard.

GETTING STARTED

This chapter describes the T3MIL50/50X, including its main features as well

as its front and rear panels. After going through the panel overview, follow the

Power-up sequence before attempting to use the instrument.

Please note the information in this manual was correct at the time of printing.

However as Teledyne LeCroy continues to improve its products, changes can

occur at any time without notice. Please see the Teledyne LeCroy website for

T3MIL50/50X Characteristics

T3MIL50 and T3MIL50X are modern high precision programmable DC

Milli-ohm meters suitable for low resistance measurements of switches, relays,

connectors, PCB tracks and a variety of other devices. The meters feature a

color TFT-LCD screen with easy-to-read measurement results. With the

easy-to-use features, superior performance and automatic test interfaces, these

meters are dependable instruments for resistance measurements.

Easy to Use

Features

Each test function on the T3MIL50/50X can be easily

activated by pressing a single front panel key. All the

settings and measurement results are displayed and set on

the TFT-LCD panel at the same time making each

function naturally intuitive to use.

Each primary and secondary measurement result is

displayed prominently on the display along with any

corresponding settings. Sequential measurement results,

such as those from the scan or binning function, are

tabulated in an intuitive and easy-to-read format.

In addition, the meters can recall previously used settings

upon startup, allowing the meter to be ready the next

time it is used in a matter of moments. The meters can

also save or recall up to 20 sets of function settings.

Performance

The T3MIL50/50X has nine selectable measurement

ranges from 5mΩ to 5MΩ, a constant current source of

1uA to 1A, an accuracy of up to 0.05%, a 0.1uΩ

resolution and performs measurements using four wire

Kelvin connections for accurate, consistent

measurements.

The ability to choose between high accuracy

measurements at 10 samples/sec (full scale at 50000

counts) or high speed measurements at 60 samples/sec

(full scale at 50000 counts), allows the T3MIL50/50X the

flexibility to fulfill a number of different measurement

roles.
