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.
