ADP30x Probe
Maintenance
Calibration Interval
This probe has no adjustments. The recommended calibration interval is one
year. (A Performance Verification Procedure is included in this manual.)
Cleaning
Clean only the exterior surfaces of the probe using a soft cloth or swab
dampened with 75% isopropyl alcohol. Do not use harsh chemicals or abrasive
elements. Probe is not water proof. Under no circumstances submerge the
probe or allow moisture to penetrate it.
Service Strategy
The ADP30x series probes utilize fine-pitch surface mount devices. It is,
therefore, impractical to attempt 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 for a modest fee. You must return the defective probe in
order to receive credit for the probe core.
WARNING No user serviceable components inside. Do not remove
covers. Refer servicing to qualified personnel.
Troubleshooting
If the probe is not operating properly the problem may be the way in which it is
used. Before assuming that the probe is defective, perform the following
troubleshooting procedures:
1. For Teledyne LeCroy LT and LC series scopes, verify that the firmware
version is 8.5 or higher.
2. Waveform is inverted. — Make sure that the + lead (Red) is connected to
the proper test point.
3. No DC. — Make sure that the attachment accessory is completely plugged
onto the lead.
4. No output signal. — Make sure that DC coupling is selected.
