Replacement Strategy - Agilent Technologies E6198B User Manual

A
Switch/Load Unit And Card Specifications
Number of Operations. If you know the applied load and life
specifications for a load, you can replace relays after a
predetermined number of contact closures. The expected life of
5 8
the relays range from 1x10 operations at full load to 1x10
operations for mechanical end-of-life (no load).

Replacement Strategy

The best strategy depends on your application. Replace
individual relays if they are used more often or at higher loads
than others. If all the relays see similar loads and switching
frequencies, the entire circuit board can be replaced as end of
relay life approaches. Weigh the sensitivity of the application
against the cost of replacing relays with some useful life
remaining.
Relays that wear out normally or fail due to misuse should not be

considered defective and are not covered by the product's warranty.
