physical strain to the probe cable, such as kinking, excessive bending, or pulling. Visible dents in the cable will increase
signal aberrations.
CAUTION: To prevent damage to the probe, always use an antistatic wrist strap connected to a static-controlled
workstation when you handle the probe. The probe input contains electronic components that can be damaged by
contact with high voltages, including static discharge.
Observe the following precautions when using the probe. Do not do any of the following:
• Drop the probe or subject it to physical shock
• Subject the probe to adverse weather conditions
• Kink or fold the probe main cable tighter than a 2.5 inch radius; minimum bend radius for the solder tips is 0.25 inch
(6.35 mm)
• Solder the tips with excessive heat or duration
• Injure yourself with the sharp tips
See Best practices on page 35.
Cleaning the probe
CAUTION: To prevent damage to the probe, do not expose it to sprays, liquids, or solvents. Avoid getting moisture
inside the probe during exterior cleaning.
Do not use chemical cleaning agents; they may damage the probe. Avoid using chemicals that contain benzine, benzene,
toluene, xylene, acetone, or similar solvents.
Clean the exterior surfaces of the probe with a dry, lint-free cloth or a soft-bristle brush. If dirt remains, use a soft cloth or
swab dampened with a 75% isopropyl alcohol solution and rinse with deionized water. A swab is useful to clean narrow
spaces on the probe; use only enough solution to dampen the swab or cloth. Do not use abrasive compounds on any part of
the probe.
Returning the probe for servicing
If your probe requires servicing, you must return it to Tektronix. If the original packaging is unfit for use or not available, use
the following packaging guidelines:
Preparation for Shipment
Use a corrugated cardboard
shipping carton having inside
dimensions at least one inch
greater than the probe
dimensions. The box should have
a carton test strength of at least
200 pounds.
Put the probe into an antistatic
bag or wrap it to protect it from
dampness.
Place the probe into the box and
stabilize it with light packing
material.
Seal the carton with shipping
tape.
Refer to Contacting Tektronix at
the beginning of this manual for
the shipping address.
