ST-Series Warranty, Installation, Service, and Repair Policies
Warranty:
Zmetrix warrants ST-series controlled impedance test systems to be free from defects in material and
workmanship for two years from the date of original purchase. During the warranty period, Zmetrix will
repair, or at its option, replace any defective component(s) without charge for parts or labor.
The Zmetrix warranty applies only to products manufactured by Zmetrix. Accessories and items not
manufactured by Zmetrix are covered by the warranty of the original equipment manufacturer. Product
defects caused by misuse, accidents, or user modification are not covered by this warranty. No other
warranties are expressed or implied. Zmetrix is not responsible for consequential damages.
Installation:
Installation of ST-series systems is not a technical or time consuming process. The ST-series are USB devices,
and installation is primarily a software function. The ST-series comes ready to take measurements.
Real Time Diagnostics:
The ST-series continually generates a file named TDR.csv. This file contains a “snapshot”of the system
electronics for the last measurement. In the event of a serious malfunction, e-mail that file to
www.zmetrix.com and our engineers will be able to diagnose system issues.
A Note on Repairs:
The typical repair for a TDR system is due to an ESD event originating at one of the input/output connectors.
As part of the ST-series design, these events are dramatically reduced when compared to our competitors.
Additionally, those same design features dramatically reduce the cost of a repair due to ESD.
