Introduction

The Teledyne LeCroy PP026 is a passive high impedance voltage

oscilloscope probe designed and calibrated for use with general purpose

oscilloscopes having an input impedance of 1 MΩ and can be compensated

for use with instruments having an input capacitance between 10 to 20 pF.

It is compatible with oscilloscopes that automatically detect probe

attenuation and adjust their readout accordingly.

Definitions (per EN 61010-031)

1) Measurement Category I (CAT I)refers to measurements performed on circuits not directly

connected to mains.

2) Measurement Category II (CAT II) refers to measurements performed on circuits directly

connected to the low-voltage installation.

3) Pollution Degree 2 refers to operating environment where normally only dry, non-conductive pollution

occurs. Temporary conductivity caused by condensation must be expected.

EC Declaration of Conformity

The probe is marked with this symbol to show compliance was

demonstrated to the specifications listed in the Official Journal of

the European Communities: Low Voltage Directive 2006/95/EC:

EN 61010-031/A1:2008 Safety requirements for electrical equipment for

measurement, control and laboratory use – Part 031: Safety requirements

for handheld probe assemblies for electrical measurement and test.

EU RoHS Compliance

The probe and its accessories conform to the 2011/65/EU RoHS2 Directive,

as they have been classified as Industrial Monitoring and Control

Equipment (per Article 3, Paragraph 24) and are exempt from RoHS

compliance until 22 July 2017 (per Article 4, Paragraph 3).

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 or disconnect probes while they are connected to a voltage

source.

Operator’s Manual

Do not overload. Do not apply any potential to the probe leads that exceeds

the maximum rating of the probe. Always comply with the Voltage vs.

Frequency Derating Curve.

Observe all terminal ratings. Observe all markings on the oscilloscope

before connecting. Consult the oscilloscope product manual for further

ratings information.

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 PP026 BNC Box until you

achieve a flat-topped square wave (see figure below):

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, high-frequency trimmers on

the PP026 BNC Compensation Box.

3. Adjust HF2 then HF1 until you achieve a flat-topped square wave (see

figure below).
