Maintenance
This probe is a high quality, precision instrument. To maintain accuracy and signal fidelity,
mechanical shock should be avoided, as well as damage to the cable through excessive
bending.
To achieve the small 2.5 mm tip size, the input tip diameter is narrower than those in
larger probes. Avoid placing excessive force sideways on the tip. Should the tip become
damaged, it may be replaced. Other maintenance and component replacement should be
referred to qualified personnel.
Cleaning
The outside of the probe should cleaned with a soft cloth dampened with either
deionized / distilled water or isopropyl alcohol. Allow the surface to dry completely
before returning the probe to service. Never immerse the probe in any liquid.
Calibration Interval
To guarantee accurate performance, you should have the probe calibrated every 12
months. Avoid exposing the probe to extreme mechanical shock and excessive bending of
the cable because these may alter the calibration.
Service Strategy
The AP033 circuits utilize fine pitch surface mount devices; it is, therefore, impractical to
attempt component-level repair in the field. Defective probes must be returned to a
Teledyne LeCroy service facility for diagnosis and exchange. A defective probe under
warranty will be replaced with a factory refurbished probe. A probe that is not under
warranty can be exchanged for a factory refurbished probe. A modest fee is charged for
this service. The defective probe must be returned in order to receive credit for the probe
core.
