General Safety Summary
Read the following safety precautions carefully to avoid any personal injuries or
damage to the instrument and any products connected to it. Use the instrument only
as specied.
Use only the power cord supplied with the instrument.
Ground the instrument.
The instrument is grounded through the ground conductor of the power cord. To avoid
electric shock, always connect to grounded outlets. Make sure the instrument is
grounded correctly before connecting its input or output terminals.
Connect the signal wires correctly.
To avoid damage, observe input polarity and maximum voltage/current ratings at all
times.
Observe all terminal ratings and signs on the instrument to avoid re or
electric shock. Before connecting to the instrument, read the manual to understand
the input/output ratings.
Do not operate with suspected failures. If you suspect that the product is
damaged, contact the Teledyne LeCroy service department immediately.
Do not operate in wet/damp conditions.
Do not operate in an explosive atmosphere.
Keep the surface of the instrument clean and dry.
Avoid circuit or wire exposure. Do not touch exposed contacts or components
when the power is on.
Do not operate without covers.
Do not operate the instrument with covers or panels removed.

IV
Use only the fuse specied for the instrument.
Use proper over-voltage protection.
Use anti-static protection. Operate in an anti-static protected area. Ground
measurement cable conductors before connecting to the instrument to discharge any
static electricity before connecting the cables to the instrument.
Observe ventilation requirements. Ensure good ventilation. Check the vent and fan
regularly to prevent overheating.
Safety Terms and Symbols
The following terms may appear on the instrument:
DANGER: Direct injury or hazard may occur.
WARNING: Potential injury or hazard may occur.
CAUTION: Potential damage to instrument/property may occur.
CAT I (1): IEC Measurement Category I, applicable for making measurements on
‘other’ circuits that are not directly connected to mains. See p. 6.
CAT II: IEC Measurement Category II, applicable for making measurements on
circuits connected directly to utilization points (socket outlets and similar points) of
the low voltage mains installation.
See page 6
(1) CAT I as dened in IEC/EN 61010-031:2008. Note that Measurement Category I
was removed in IEC/EN 61010-031:2015 and replaced by ‘O’, indicating "other
circuits that are not directly connected to mains."

Operating Environment
Temperature: 0 °C to 40 °C
Humidity: 5% to 90% relative humidity (non-condensing) up to +30 °C. Upper limit
derates to 50% relative humidity (noncondensing) at +40 °C.
Altitude: ≤ 2000 m
Use indoors only.
Pollution Degree 2. Use in an operating environment where normally only dry, non-
conductive pollution occurs. Temporary conductivity caused by condensation should
be expected.
AC Power
Input Voltage & Frequency: 100-120 V at 50/60 Hz or
200-240 V at 50/60 Hz
Manual AC selection with a slide switch.
Power Consumption: 20 W maximum
Mains Supply Connector: CAT II per IEC/EN 61010-1:2010, instrument intended to
be supplied from the building wiring at utilization points (socket outlets and similar).
Fuse Type
Current Input Terminal: 250 VAC F 10 A, 3 AG
AC Mains: 250 VAC F 300 mA, 5x20 mm

VI
Input terminal protection limitation.
Protection limitation is defined for the input terminals:
1. Main input (HI and LO) terminal
HI and LO terminals are used for Voltage, Resistance, Capacitance,
Continuity, Frequency, Diode and Temperature measurements. Two
protection limitations are defined:
HI-LO protection limit: 1000VDC or 750AVC. This is the maximum
measurable voltage. The limitation can be expressed as 1000Vpk.
LO-ground protection limit: LO terminal can safely “float” 500Vpk
relative to ground. The maximum protection limitation of the HI terminal
relative to ground is 1000Vpk. Therefore, the sum of the “oat” voltage and
the measured voltage cannot exceed 1000Vpk.
2. Sampling (HI Sense and LO Sense) terminals
HI Sense and LO Sense are used for 4-wire Resistance measurements. Two
protection limits are defined:
HI Sense-LO Sense protection limitation: 2000Vpk.
LO Sense-LO Sense protection limitation: 2Vpk.
3. Current input (I) terminal
I and LO terminals are used for current measurement. The maximum current
which go through the Iterminal 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 protected, only use the fuse of specified type and value to replace
this fuse.

VII
IEC Measurement Category II Overvoltage Protection
To avoid the danger of electric shock, the Digital Multimeter provides overvoltage
protection for line-voltage mains connections that meet both of the following
conditions:
1. The HI and LO input terminals are connected to the mains under
Measurement Category II conditions described in the warning below.
2. The maximum line voltage of the mains does not exceed:
300 VAC for T3DMM4-5
600 VAC for T3DMM5-5 and T3DMM6-5
WARNING:
IEC Measurement Category II includes electrical devices connected to mains at an
outlet on a branch circuit, such as most small appliances, test equipment, and
other devices that plug into a branch outlet or socket.
The multimeter can make measurements with the HI and LO inputs connected to
mains in such devices (≤ 300 VAC for T3DMM4-5 and ≤ 600 VAC for T3DMM5-
5/T3DMM6-5) or to the branch outlet itself.
However, the HI and LO terminals of the multimeter 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 the multimeter.
Limits for Measurements on Other Circuits Not Directly Connected to Mains
Max. rated input voltage: 1000 Vrms
Transient overvoltage: 4000 Vpk
WARNING:
Voltages above 300 VAC (for T3DMM4-5) or 600 VAC (T3DMM5-5 / T3DMM6-5)
can only be measured in circuits that are isolated from mains. However, there may
be transient over voltage in circuits that are isolated from mains. The multimeter is
able to withstand occasional transient overvoltage up to 4000 Vpk. Please don’t
use this instrument to measure circuits where transient overvoltage may exceed
this level.

Daily Maintenance and Cleaning
Maintenance
When storing or using the instrument, please avoid the liquid crystal display
from being exposed for long periods of time to direct sunlight.
NOTE:
To avoid damage to the instrument or probe, please do not place them in
mist, liquid or solvent.
Cleaning
Please clean the instrument or probe often according to its use.
•Wipe the external dust o the instrument and probe with a soft rag. Be
careful not to scratch the transparent plastic protective screen when
cleaning the screen.
•Use a damp soft rag to clean the instrument after removing the power
cord. Or use a 75% isopropyl alcohol and water solvent to give a more
thorough clean.
NOTE:
•To prevent the surface of the instrument or probe from damage, please
do not use any corrosive or chemical cleaning agents.
•Please make sure the instrument is dry before reconnecting the power
cord and restarting it, to avoid short circuit or personal injuries caused by
water.
