Introduction
Teledyne LeCroy PP021 is a passive high impedance voltage oscilloscope
probe designed and calibrated for use with general purpose oscilloscopes
having an input impedance of 1 MΩ. It can be compensated for use with
instruments having an input capacitance between 14 and 25 pF. It is
compatible with oscilloscopes that automatically detect probe attenuation
and adjust their readout accordingly.
To avoid electric shock, keep fingers behind the probe’s finger
guard during use.
Rated for indoor use only. Do not operate where conductive
pollutants may be present.

Definitions:
Measurement Category II (CAT II) refers to measurements performed on circuits directly connected to
utilization points (socket outlets and similar) of the low-voltage mains installation.
Pollution Degree 2 refers to an operation environment where normally only dry non-conductive
pollution occurs. Temporary conductivity caused by condensation should be expected.

General Safety Information
Observe generally accepted safety procedures in addition to those
listed here to avoid personal injury or damage to equipment. The
overall safety of any system incorporating this accessory is the
responsibility of the assembler of the system.
Connect only to grounded instruments. Use only with compatible Teledyne
LeCroy oscilloscopes that have their BNC input connected to an earth
ground. Do not connect the probe reference lead to any point which is at a
potential other than earth ground.
Connect and disconnect properly. Connect probe to the oscilloscope before
connecting it to the test circuit. Disconnect the probe input and reference
lead from the test circuit before disconnecting from the oscilloscope. Do
not connect/disconnect probes while connected to a voltage source.
Do not overload. Do not apply any potential to the probe leads that exceeds
the maximum rating of the probe. Observe all terminal ratings on the
oscilloscope before connecting. Consult the oscilloscope product manual
for further ratings information.
Always comply with the Voltage vs. Frequency Derating Curve.
Do not remove probe casing. Touching exposed connections may result in
electric shock.
Use indoors only within operational environment listed. Do not use in wet or
explosive atmospheres. Keep product surfaces clean and dry.
Handle with care. Probe tips are extremely sharp and may puncture skin or
cause other bodily injury if not handled properly.
Keep fingers behind the finger guard of probe body and accessories.

Do not operate with suspected failures. Before each use, inspect the probe
and accessories for any potential damage such as tears or other defects in
the probe body, cable jacket, accessories, etc. If any part is damaged, cease
operation immediately and sequester the probe from inadvertent use.
Cleaning
•Clean only the exterior of the probe, cables, and accessories. Use a
soft cotton cloth moistened with a mild detergent and water solution.
Do not allow any portion of the probe to be submerged at any time.
•Dry the probe and accessory thoroughly before attempting to make
any voltage measurement.
•Do not subject the probe to solvents or solvent fumes as these can
cause deterioration of the probe body, cables, and accessories.

Probe Compensation
Proper compensation of the probe is required to assure amplitude accuracy
of the waveform being measured by matching the probe to the
oscilloscope’s input capacitance. Compensation should be adjusted
whenever the probe is connected to or transferred between oscilloscopes.
Low Frequency
1. Apply a 1 kHz square wave to the probe or connect to the
oscilloscope’s calibrator output.
2. Adjust the single LF trimmer located on the PP021 BNC
Compensation Box until you achieve a flat-topped square wave.
High Frequency
1. Apply a 1 MHz square wave to the probe (< 0.7 ns rise-time).
2. Remove the plastic caps from the two, HF trimmers on the PP021
BNC Compensation Box.
3. Adjust HF2 then HF1 until you achieve a flat-topped square wave.

Probe Accessories
Probe Tips
Both the rigid probe tip and the spring tip can be screwed on to the probe
body by hand.
Be sure not to overtighten the tips to avoid damaging the threads.
Ground Accessories
The ground lead and the short collar are attached to the probe at the time
of shipping. To replace the ground lead with the swivel lead adapter,
unscrew the short collar from the probe and remove the ground lead.
Replace the short collar to hold the swivel lead adapter in place.
Alternatively, the long collar can be pushed onto the probe body and used in
conjunction with the ground spring, BNC adapter or PCB adapter.
