DL-ISO High Voltage Optically Isolated Probes
Care and Maintenance
Checking Probe Cable
Before each use, check the fiber-optic cable for tears in the soft outer sleeve. If the corrugated
sleeve beneath is visible at any point, stop using the probe and secure it from inadvertent use.
Cleaning the Probe Body
Clean only the exterior surfaces of the device using a soft cloth or swab dampened with water or
75% isopropyl alcohol solution. Do not use harsh chemicals or abrasive cleansers. Dry the probe
and accessories thoroughly before making any voltage measurements.
CAUTION: The DL-ISO probe is not waterproof. Under no circumstances submerge the
probe in liquid or allow moisture to penetrate it.
Calibration Interval
The recommended calibration interval is one year. A performance verification procedure is included
in this manual. The complete performance verification should be performed as the first step of
annual calibration.
Service Strategy
The DL-ISO probe utilizes fine-pitch surface mount devices. Defective probes must be returned to a
Teledyne LeCroy service facility for diagnosis and exchange.
CAUTION: Refer all servicing to qualified personnel. A defective probe under warranty will
be replaced with a factory refurbished probe.
Probes not under warranty can be exchanged for a factory refurbished probe for a modest fee.
Replacement probes are factory repaired, inspected, and calibrated to the same standards as a
new product. You must return the defective probe in order to receive credit for the probe core.
