Tektronix recalls two models of oscilloscopes

Officials of Tektronix Inc. of Beaverton, Ore., are recalling their model TDS210 and TDS220 oscilloscopes after determining that incorrect use could cause the ground connections to fail. A failure of the ground connection can potentially expose the user to the risk of serious injury or death, Tektronix officials say, although they add that they are not aware of any injuries to users. If a user incorrectly connects a probe ground lead to a voltage source, or incorrectly touches the ground ring near the probe tip to a voltage source, a circuit board trace in the oscilloscope`s electrical ground path may open, causing the unit to be improperly grounded. The recall applies to 60,000 units. For more information, contact Tektronix by phone at 800-835-9433, ext. 2400, or on the World Wide Web at http://www.tek.com/measurement/ - J.K.
