Guarding and shielding
You can optimize source-measure performance and safety with the effective use of guarding and
shielding (noise and safety shields).
Safety shield
A safety shield must be used whenever hazardous voltages (>30 V RMS, 42 V peak) will be
present in the test circuit. To prevent electrical shock that could cause injury or death,
never use the Series 2600B in a test circuit that may contain hazardous voltages without a
properly installed and configured safety shield.
The safety shield can be metallic or nonconductive, and must completely surround the DUT test
circuit. A metal safety shield must be connected to a known protective earth (safety ground). See
(see "
" on page 2-71) for important safety information on the use of a metal or a
nonconductive enclosure.
