Safety information
To avoid personal injury and to prevent fire or damage to this product or products connected to it,
review and comply with the following safety precautions. Be aware that if you use this probe
assembly in a manner not specified the protection this product provides may be impaired.
Only qualified personnel should use this probe assembly.
Use only grounded instruments.
Do not connect the probe ground lead to a potential other than earth ground. Always make sure the
probe and the measurement instrument are grounded properly.
Connect and disconnect properly.
Connect the probe output to the measurement instrument and connect the ground lead to earth
ground before connecting the probe to the circuit under test. Disconnect the probe input and the
probe ground lead from the circuit under test before disconnecting the probe from the measurement
instrument.
Observe probe ratings.
Do not apply any electrical potential to the probe input which exceeds the maximum ratings of the
probe. Be sure to comply with the voltage versus frequency derating curve on page 6. Under no
circumstances must be the probe be used on mains or line voltages.
Do not use a suspected failed probe.
Refer to qualified service personnel.
Indoor use only.
Do not operate in wet or damp environments. Keep product surfaces dry and clean.
Do not operate the product in an explosive atmosphere.

About the TA061 probe
The TA061 probe sets new standards in high performance probing. The compact design with only 2.5
mm housing diameter at the probe tip is ideal for measurements of SMT components. It provides a
much better visibility over of the device under test than conventional 5 mm probe housing designs.
The exchangeable probe tip, a special Pico Technology feature, is also available for the TA061 probe.
The gold-plated spring contact and the rigid tip are only 0.5 mm in diameter. Replacement of the tip is
easy and convenient for the engineer.
Particularly for HF measurements on IC's, a short as possible ground connection is recommended.
Due to long ground leads, most conventional adaptors bring additional inductance and resonances into
the measurement which will result in false or inaccurate readings. The innovative IC contact system of
the TA061 probe, with 5 different IC adapters from 0.5 to 1.27 mm pitch in combination with the ground
blade and IC ground copper pad, is the ideal solution for short-circuit-safe, reproducible and accurate
measurements.
With these great advantages and over 30 accessories, the new TA061 probe offers various
configurations to solve most connection problems.
IC contact system with IC adapter, ground blade and
IC ground copper pad.

Handling
Handle the probe with care, especially when it is fitted with the extra thin and sharp
spring contact tip, to avoid any injury. Note that the probe cable is a sensitive part of the
probe. Do not damage through excessive bending or pulling. Avoid mechanical shock to
this product in general to guarantee accurate performance and protection.
Maintenance
Cleaning
To clean the exterior of the probe use a soft cloth moistened with either distilled water or isopropyl
alcohol. Before use allow the probe to dry completely.
Changing the probe tip
To change the probe tip use pliers to grip and pull it carefully straight out of its contact socket, along the
axis of the probe. Do not grip the white plastic insulator or the housing with pliers, because the tip could
be squeezed and become difficult to remove, or the probe could be damaged.
If the probe tip is removed, the new tip can be inserted with pliers into the contact socket, along the axis
of the probe. In order to insert the probe tip completely into the housing, carefully press the probe tip
against a hard surface.
Use pliers to grip and pull the probe carefully out
of its contact socket. Do not grip the white plastic insulator or the
probe housing with pliers.
