Testing & Maintaining 
the Agilent V24/V26 
Series
Safety Tests
For Europe and Asia-Pacific:
according to IEC 601-1:1988+A1+1991+A2:1995 = EN60601-1:1990+A1:1991+A2:1995
For the US:
according to UL 2601-1
The test procedures outlined in this section are to be used only for verifying safe 
installation or service of the product in question. 
The set-ups used for these tests and the acceptable ranges of values are derived from 
local and international standards but may not be equivalent. 
These tests are not a substitute for local safety testing where it is required for an 
installation or a service event. 
If using the Metron Safety tester, use your local regulation to perform the test, for 
example, in Europe IEC601-1/IEC601-1-1, and in the U.S. UL2601-1. The Metron 
Report should print results with the names listed below, along with other data.
The Safety Tests required to ensure that the V24/V26 Series is in safe working order 
are detailed in the following tables.
