General Safety Summary
Read the following precautions carefully to avoid any personal injuries, or damage to the instrument or products connected to it. Use the instrument only as specified.
Use only the power cord supplied for 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 wire 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 fire 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 instrument 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 touching exposed circuits or wires.
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.
Use only the fuse specified for the instrument.
Use proper overvoltage 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 I1: IEC Measurement Category I, applicable for making measurements on ‘other’ circuits that
are not directly connected to mains. See p. v.
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 p. v.
1) CAT I as defined 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 cir-
cuits that are not directly connected to mains.”
Saftey Symbols
The following symbols may appear on the instrument:

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 (non-condensing) 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
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

T3DAQ1-16 User Manual
Input Terminal Protection Limitation
Protection limitation is defined for the input terminal.
1. Main Input (HI and LO) Terminals
HI and LO terminals are used for Voltage, Resistance, Capacitance, Continuity, Frequency,
Diode and Temperature measurement. Two protection limitations are defined:
• HI-LO protection limitation: 1000 VDC or 750 VAC. This is the maximum measurable
voltage. The limitation can be expressed as 1000 Vpk.
• LO ground protection limitation: LO terminal can “float” 500 Vpk relative to the ground
safely. 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 can’t exceed
1000 Vpk.
2. Sampling (HISense and LOSense) Terminals
HISense and LOSense terminals are used for 4-wire Resistance measurement. Two protection limitations are defined:
• HISense-LOSense protection limitation: 2000 Vpk.
• LOSense-LOSense protection limitation: 2 Vpk.
3. Current Input (I) Terminal
The I terminal is used for current measurement. The maximum current which can go through
the I terminal is limited to 10 A by the fuse on the back panel.
NOTE: Voltage on the current input terminal corresponds to voltage on the LO terminal. To
keep good protection, only use a fuse of the specified type and value to replace this fuse
iv
T3DAQ1-16 User Manual
IEC Measurement Category II Overvoltage Protection
To avoid the danger of electric shock, the Data Acquisition Unit 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: 600 VAC for the instrument.
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 DAQ is capable of making measurements with the HI and LO inputs connected to mains in
such devices (≤ 600 VAC) or to the branch outlet itself.
However, the HI and LO terminals of the DAQ 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
DAQ.
Limits for Measurements on Other Circuits Not Directly Connected to Mains
Max. rated input voltage: 1000V
Transient overvoltage: 4000V
WARNING:
Voltages above 600 VAC 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 DAQ 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.

Scanner Card Connections
An example of 2-wired connection application is shown below.
First 12 channels can be used to measure DCV/DCI ACV/ACI/CAP/FREQ/DIODE/CONT/TEMP
and the last 4 channels are dedicated to current measurement.
4-Wire Resistance measurement example is shown below.
CH1 to CH6 can be used for measurements and CH7 to CH12 can be used as sense channels. To
minimize voltage errors, the remote sense connections (CH7,CH8 etc..) should be made as close
to the device-under-test (DUT) as possible.
