Teledyne Lecroy DL-ISO User manual

Probe Assembly and Connection
1. Connect the supplied AC to DC adapter to the DC inlet
port on the control module, then connect to AC power.
CAUTION: Use only the adapter shipped with the
probe. The probe must be powered from a supply
that provides appropriately isolated and floating
output voltage (i.e., no Earth connection).
2. Connect the probe to the oscilloscope through the
ProBus interface.
3. Insert the probe tip into the
connector on the probe head.
Be sure the arrows on the
connectors align.
4. Connect the tip to a de-energized
circuit.
Connecting Tips
MMCX tips can be used for low-voltage signals up to their
rated amplitude. Seat MMCX tips directly into MMCX
connectors on the circuit.
To connect MMCX tips to square-pin
headers, attach the MMCX to square-
pin adapter to the tip, then press it
onto the pins.
Note: The order of the three pins
in the adapter is reference-signal-
reference.
HV square-pin tips connect to
differential +ve and -ve signals on
circuits. On the tip, you will see a
red + and a white - indicating which
side connects to signal and which to
reference.
Most tip accessories have a red and a black interface.
Red connects to signal and black connects to reference.
Tip Accessories
WARNING: The probe, tips and accessories are
classied No Rated Measurement Category per
IEC/EN 61010-2-030:2021 denitions. No Rated
Measurement Category applies to circuits not
directly connected to the mains supply. The
measurement terminals of the probe as well as all
accessories are to be used only for measurements
on circuits not directly connected to the mains.
The probe and accessories are not rated for CAT II,
III or IV measurements.
WARNING: The Measurement Category and voltage
rating is the lower of the probe tip or accessory
used. Do not exceed the CAT, voltage or current
rating of the lowest rated individual component.

Operation
When the probe is connected to an oscilloscope, the DLxx-ISO
probe dialog is displayed behind the input channel setup
dialog (Cn). It shows the connected probe’s attributes.
Use the buttons for Precision Gain Calibration and Auto Zero
to initiate those procedures.
Calibration Status indicator shows whether the Gain
Calibration in use is valid (green checkmark Pass) or is invalid
and should be repeated (red X Fail).
Warming Up indicator shows whether probe is still in warm-
up phase or ready for use.
Use the External Power On/Off checkbox to turn off power
from the AC to DC adapter without physically disconnecting it
from the probe.
Precision Gain Calibration
Perform a Precision Gain Calibration prior to each
use to ensure specied gain accuracy for the current
conguration. Calibration includes an Auto Zero procedure.
1. De-energize the circuit under test. It is not necessary
to disconnect the probe.
2. Warm up oscilloscope and probe until the “warming
up” indicator on the probe dialog disappears.
3. Touch the Precision Gain Calibration button.
Each calibration is valid for the same conguration and
temperature (±5 ºC ) at which it was last performed. The
temperature is polled to determine whether the probe is
still in the ±5 ºC valid temperature range.
Calibrations are not cached, they must be repeated
whenever the temperature changes more than ±5 ºC or
the probe is disconnected and reconnected.

WARNING: The DL-ISO probes contain multiple
lasers, exposing which may cause laser burns. Do
not remove any plastic or metal covers or otherwise
attempt to disassemble the probe.
Using controls, adjustments or procedures other than
those specied in the product manual may result in
exposure to hazardous levels of invisible radiation.
The probe uses optical bers within a single cable
between the probe head and control module. Therefore,
standard optical ber handling practices are required.
Avoid tight radius bends, crushing, crimping, twisting
or otherwise stressing the ber-optic cable.
Minimum cable radius bend is 2 in (5.1 cm); avoid
making loops smaller than 4 in (10.2 cm).
Before each use, inspect the ber-optic cable for
damage such as tears in the outer sleeve or other
defects. If the corrugated plastic inner sleeve is visible
or punctured, cease operation immediately and secure
the probe from inadvertent use.
Safety Symbols
These symbols appear on the probe or in documentation.
Terms
The terms isolated and electrically floating are used in
documentation to indicate measurements where there is
no direct conduction path to earth ground.

HIGH VOLTAGE WARNING. Risk of electric
shock or burn.
CAUTION of damage to equipment, or
WARNING of hazard to health. Refer to the
accompanying information in the product
manual to protect against personal injury or
damage. Do not proceed until conditions are
fully understood and met.
ESD CAUTION. Risk of Electrostatic Discharge
(ESD) that can damage equipment if anti-
static measures are not taken.
Laser Safety WARNING.
The overall safety of any system incorporating this
probe is the responsibility of the system owner.
For use only by trained personnel. Not for use in
households or by children.
Use only as specied. Using the probe and/or the
equipment it is connected to in a manner other than
specied may impair the protection mechanisms.
Before use, test the probe with a known source to
ensure it is operating correctly.
Do not overload; observe all terminal ratings. Do not
connect the probe to any circuit that exceeds the CAT,
voltage or current ratings of the oscilloscope terminal,
probe or probe-accessory combination.
Use only accessories compatible with the probe. Use
only accessories that are rated for the application.
Using accessories other than those shipped with the
probe may create an electrical hazard.
Connect and disconnect properly. Connect the probe
to the oscilloscope before connecting to the circuit
being measured. De-energize the test circuit before
connecting/disconnecting probe tips.
Keep the probe head and ber-optic cable away from
the circuits being measured. Only tips are intended for
contact with electrical sources.
Do not excessively bend cables. Avoid tight radius
bends, crushing, crimping, twisting or otherwise
stressing cables.
Do not remove the probe’s casing. Touching exposed
connections may result in electric shock.
Do not disassemble the probe or remove inside parts.
Refer all service to Teledyne LeCroy personnel.
Use only indoors within the operational environment
listed. Do not use in wet or explosive atmospheres.
Keep product surfaces clean and dry.
Do not use damaged cables. Before each use, check all
cables for damage to the protective insulation.
Do not operate with suspected failures. Before each
use, inspect the probe and accessories. If any part is
damaged, cease operation immediately and secure the
probe from inadvertent use.

General Safety Precautions
CLASS 1 LASER PRODUCT
Laser Safety
The unique common mode voltage range of the probe
system allows it to be used in the presence of high-
frequency/high-voltage common mode signals, but it is
important to observe all precautions while using it.
WARNING: RF burns or electric shock can occur
when using the DL-ISO probes. The plastic case of
the probe head and tip shields do not provide safe
isolation from hazardous common mode voltages. Do
not access the probe while measuring signals in the
RF burn risk area.
Clearance Requirements
Maximum safe handling limits for common mode voltages
between the probe head and tips with respect to earth ground.
WARNING: Maintain 1m (~40 in) safe clearance of the
probe head and tip in all directions when connected to
an energized circuit. Place the oscilloscope and any
equipment you need to access at least 1m away from
the circuit and probe head.
